470     lower right corner, center labels for selections, initialize controls
471     in reasonable order for keyboard navigation.
472    
473     * Thuban/UI/projdialog.py (ProjFrame.__init__, ProjFrame.__doLayout)
474     (ProjFrame.__DoOnProjAvail): Determine position of current projection
475     using the wxListBox.FindString() method. Still a problem (#1886)
476

478     (Classifier.__init__, SelectPropertiesDialog.__init__)
479    
480     * Thuban/UI/classgen.py (ClassGenDialog.__init__,

487     Button to 'Export'. Center Buttons in Selection Box, set Focus to
488     Grid.
489     (LayerTableFrame.OnKeyDown()): New, bound to the grid with EVT_KEY_DOWN,
490     changes focus to the Selection when pressing "Alt-S".
491    
492     * Thuban/UI/legend.py (LegendTree.__SetVisibilityStyle): Only gray out
493     the text if not visible. The italic font sometimes exceeds the

497 jonathan 971
498 jonathan 975 * Thuban/UI/dock.py (DockFrame): Rename references to _OnClose
499     to OnClose so that Thuban closes correctly.
500    
501     * Thuban/UI/mainwindow.py (MainWindow.OnClose): Call
502     DockFrame.OnClose, not DockFrame._OnClose.
503    
504     2003-05-21 Jonathan Coles <[email protected]>
505    
506 jonathan 971 * Thuban/Model/classgen.py (ClassGenerator.GenQuantiles): Remove
507     references to 'inf' and use new Range __init__ to pass floats
508     directly rather than converting them to strings first.
509     Fixes RTBug #1876.
510    
511     * Thuban/Model/classification.py (ClassGroupRange.SetRange):
512     Use new Range ___init__ to pass floats.
513    
514     * Thuban/Model/layer.py (RasterLayer.__init__): Test if the
515     filename is a valid image file. Throw IOError otherwise.
516    
517     * Thuban/Model/range.py: Brought over new Range from SciParam that

538     to suppress excessive messages when selecting many rows.
539     Fixes RTBug #1880.
540    
541     * Thuban/UI/view.py: Added checks against if scale == 0. This
542     is a serious problem that can occur when an image without
543     geo data is loading and causes the map projection bounds to
544     go to infinity. Right now, the solution is to simply try
545     to recover.
546    
547     * extensions/thuban/cpl_mfile.cpp (MFILEClose): Make sure
548     to set the MFILEReceiver attributes even if the data is NULL.
549    
550     * extensions/thuban/gdalwarp.cpp: Improved the error handling
551     and passed GDAL messages back up to the Python layer. Also
552     tried to fix some memory leaks that were present in the original

554    
555     * test/test_range.py: Copied over tests from SciParam. Removed
556     tests against importing. Fixes RTBug #1867.
557

584    
585     * Thuban/UI/mainwindow.py (MainWindow): Renamed _OnClose() back to
586     OnClose() to keep in sync with extensions. Internally Thuban
587     still uses "underscored" names.
588    
589 jonathan 949 2003-05-20 Jonathan Coles <[email protected]>
590    
591     This puts back Raster layer support. These layers support projections
592     through the GDAL library. Currently, the CVS version is being used.
593     There are no Debian packages available although this may change soon.
594     A GDAL driver was extended to support writing to memory rather to
595     files.
596    
597     There is still some work that needs to be done, such as some error
598     handling when loading invalid images or when there is a problem
599     projecting the image. This putback simply checks in the majority
600     of the work.
601    
602     * setup.py: Add gdalwarp library extension.
603    
604     * Thuban/Model/layer.py (BaseLayer.HasClassification): New.

608     image.
609    
610     * Thuban/Model/load.py (SessionLoader.__init__): Add rasterlayer
611     tag handler.
612     (SessionLoader.start_layer): Encode the filename.

614     New. Supports reading a rasterlayer tag.
615    
616     * Thuban/Model/map.py (Map.BoundingBox): Fix typo in comment.
617    
618     * Thuban/Model/save.py (XMLWriter.encode): Don't assume that we
619     get a string in Latin1. If we get such as string convert it to
620     unicode first, otherwise leave if alone before encoding.
621     (SessionSaver.write_layer): Add support for writing both Layers
622     and RasterLayers.
623    
624     * Thuban/Model/transientdb.py (AutoTransientTable.SimpleQuery):
625     The right argument may not be a string, it could also be a Column.
626    
627     * Thuban/UI/application.py (ThubanApplication.CreateMainWindow):
628     Make initial window size 600x400. Fixes RTBug #1872.
629    
630     * Thuban/UI/classifier.py (Classifier.__init__): Rearrange how
631     the dialog is constructed so that we can support layers that
632     do not have classifications.
633     (Classifier._OnTry): Only build a classification if the layer
634     supports one.
635    
636     * Thuban/UI/legend.py: Change all checks that a layer is an
637     instance of Layer into checks against BaseLayer.

639     the layer supports classification.
640    
641     * Thuban/UI/mainwindow.py (MainWindow.NewSession,
642     MainWindow.OpenSession): Don't proceed with an action if the
643     user chooses Cancel when they are asked to save changes.
644     (MainWindow.AddRasterLayer): New. Open a dialog to allow the
645     user to select an image file. Create a new RasterLayer and add
646     it to the map.
647    
648     * Thuban/UI/renderer.py (MapRenderer.render_map): Add support
649     for rendering RasterLayer layers.
650     (MapRenderer.draw_raster_layer): Actually method that calls
651     the GDALWarp python wrapper and constructs an image from the
652     data returned.
653    
654     * Thuban/UI/tableview.py (LayerTableFrame.__init__): Change the
655     Choices symbols to match those used in the table query method.
656     Replace deprecated method calls on table with new method names.
657    
658     * Thuban/UI/view.py (MapCanvas.set_view_transform): Try to limit
659     how small the scale can get. This still needs more testing.
660    
661     * extensions/thuban/bmpdataset.cpp: New, but copied from GDAL.
662     Provides a driver to output in .bmp format.
663    
664     * extensions/thuban/cpl_mfile.cpp, extensions/thuban/cpl_mfile.h:
665     New. Provides IO routines which write to memory, rather than a file.
666    
667     * extensions/thuban/gdalwarp.cpp: New, but basically a direct copy
668     of the gdalwarp utility provided in GDAL. Added function calls
669     that can be accessed from python.
670    
671     * Data/iceland_sample_raster.thuban: New. Sample file that uses
672     a raster layer.
673    
674     * Data/iceland/island.tfw, Data/iceland/island.tif: New. Raster
675     layer image data.
676    
677     * Doc/thuban.dtd: Added rasterlayer attribute definition.
678    
679     * test/test_layer.py, test/test_load.py, test/test_save.py: Added
680     tests associated with the raster layer code.
681    
682     * test/test_transientdb.py
683     (TestTransientTable.test_auto_transient_table_query): Added a test
684     for using a Column object as the "right" parameter to a query.
685    
686 frank 924 2003-05-19 Frank Koormann <[email protected]>

701     information: Display Thuban, wxPython and Python version.
702    
703 bh 919 2003-05-16 Bernhard Herzog <[email protected]>
704    
705 bh 921 * Thuban/Model/save.py: Remove some unused imports including the
706     __future__ import for nested_scopes as Thuban relies on Python 2.2
707     now.
708     (XMLWriter.encode): Remove the special case for a None argument.
709     In the saver encode is always called with a string argument.
710    
711     2003-05-16 Bernhard Herzog <[email protected]>
712    
713 bh 919 * Thuban/UI/__init__.py: Remove the work-around for the locale bug
714     in wxPython (at least when usinvg wxGTK) prior to 2.4. The symptom
715     of the bug was that e.g. float("1.2") would fail. Thuban now
716     requires 2.4.x.
717    
718 frank 917 2003-05-16 Frank Koormann <[email protected]>

784 jonathan 899 * Thuban/UI/classgen.py (GenQuantilesPanel.GetList): Replace call
785     to table.UniqueValues() with calls that retrieve all the values
786     from the table. This will need to be replaced by a method on table
787     which can simply return the list (perhaps more efficiently).
788    
789     2003-05-12 Jonathan Coles <[email protected]>
790

823    
824     Quantiles are now available in the Classification Generator.
825    
826     Initial support for building Queries on a table. Doesn't do anything
827     but run some tests.
828    
829     * Thuban/Model/classification.py: Explicit imports.
830     (ClassGroupRange): Use the Range class to store the underlying
831     range information. The interface remains the same, except for
832     GetRange(), and you can also supply a Range object as the min
833     parameter to SetRange or __init__.
834    
835     * Thuban/Model/load.py (XMLReader.encode): New. Encodes the given
836     string appropriately for use in Thuban. Fixes RTbug #1851.
837     (SessionLoader.end_projection): Handle the context of the
838     projection tag a bit better by looking at what objects are not
839     None. There was an assumption that a projection tag for a map
840     could occur before any layers.
841     (SessionLoader.start_clrange): Provide backward compatibility for
842     reading min/max values as well as the new range parameter.
843

878    
879     * Thuban/UI/tableview.py (TableGrid.OnRangeSelect): Fix some issues
880     with correctly selecting the rows and issuing the right events.
881     Be sure to call Skip() to allow the grid to do some of its own
882     handling which allows the rows to actually be selected.
883     (LayerTableGrid.select_shapes): Rename from select_shape. Supports
884     selecting multiple shapes.
885     (LayerTableFrame): Support for building Queries.
886     (LayerTableFrame.select_shapes): Allow multiple shapes to be selected.
887    
888     * Thuban/UI/tree.py: Explicit imports.
889    
890     * Thuban/UI/view.py (MapCanvas): Delegate "SelectedShapes" so the
891     table view can call it.
892    
893     * test/test_classification.py: Explicit imports.
894     (TestClassification.test_ClassGroupRange): Fix test for new
895     Range class.

1025 bh 840 Convert all table users to use the new table interface. This only
1026     covers Thuban itself, not GREAT-ER or other applications built on
1027     Thuban yet, so the compatibility interface stays in place for the
1028     time being but it now issues DeprecationWarnings.
1029    
1030     Finally, the new Table interface has a new method, HasColumn.
1031    
1032     * Thuban/Model/table.py (OldTableInterfaceMixin): All methods

1036     for the deprecation warnings
1037

1091    
1092     * Resources/Bitmaps/fulllayerextent.xpm,
1093     Resources/Bitmaps/fullselextent.xpm: Bitmaps for layer and selection
1094     extent. These are just place holders for the real bitmaps.
1095    
1096     * Thuban/Model/layer.py (Shape): Since a Shape is immutable only
1097     calculate the bounding box once (the first time compute_bbox() is
1098     called).
1099     (Layer.ShapesBoundingBox): New. Given a list of shape ids, return
1100     the bounding box for the shapes in lat/long coordinates.
1101    
1102     * Thuban/UI/mainwindow.py: Added new "Full selection extent" menu
1103     option.
1104     (MainWindow.has_selected_shapes): New. Returns true if there are
1105     any selected shapes.

1140    
1141     Convert the table implementations to a new table interface. All
1142     tables use a common mixin class to provide backwards compatibility
1143     until all table users have been updated.
1144    
1145     * Thuban/Model/table.py (OldTableInterfaceMixin): Mixin class to
1146     provide backwards compatibility for table classes implementing the
1147     new interface
1148     (DBFTable, MemoryTable): Implement the new table interface. Use
1149     OldTableInterfaceMixin as base for compatibility

1155    
1156     * test/test_memory_table.py: New. Test cases for the MemoryTable
1157     with the new table interface.
1158    
1159     * test/test_table.py: Document the all tests in this file as only
1160     for backwards compatibility. The equivalent tests for the new
1161     interface are in test_memory_table.py and test_dbf_table.py
1162     (MemoryTableTest.test_read): field_info should be returning tuples
1163     with four items
1164     (MemoryTableTest.test_write): Make doc-string a more precise.
1165    
1166     * Thuban/Model/transientdb.py (TransientTableBase): Convert to new
1167     table interface. Derive from from OldTableInterfaceMixin for
1168     compatibility.
1169     (TransientTableBase.create): New intance variable column_map to
1170     map from names and indices to column objects
1171     (TransientTable.create): Use the new table interface of the input
1172     table
1173     (AutoTransientTable): Convert to new table interface. Derive from
1174     from OldTableInterfaceMixin for compatibility.
1175     (AutoTransientTable.write_record): Removed. It's not implemented
1176     yet and we still have to decide how to handle writing with the new
1177     table and data framework.
1178    
1179     * test/test_transientdb.py
1180     (TestTransientTable.run_iceland_political_tests)

1186     This is namely a collection of UI updates to improve user interactivity.
1187     Tabbing between controls now exists and you can use ESC to close dialog
1188     boxes; ENTER will active the default button.
1189    
1190     * Thuban/UI/classgen.py (ClassGenDialog.__init__): Rearrange the
1191     order that the controls are created so that tabbing works correctly.
1192     (ClassGenDialog.OnOK): Renamed from _OnGenerate() so that the
1193     wxDialog can handle the default button correctly.
1194     (ClassGenDialog.OnCancel): Renamed from _OnCloseBtn() for the
1195     same reasons as for OnOK.
1196     (GenUniformPanel._OnRetrieve): Call wxBeginBusyCursor/wxEndBusyCursor
1197     when we ask the table for the maximum/minimum values of a field
1198     which could take a very long time.
1199    
1200     * Thuban/UI/classifier.py (Classifier.__init__): Rearrange the
1201     order that the controls are created so that tabbing works correctly.

1203     controls are created so that tabbing works correctly.
1204    
1205     * Thuban/UI/dialogs.py: Copied NonModalDialog box and changed it
1206     to derive from a wxDialog but behave like the original implementation
1207     which was derived from a wxFrame. wxDialog provides useful key
1208     handling functionality like ESC calling OnCancel and ENTER calling
1209     OnOK which is lost with wxFrame.
1210    
1211     * Thuban/UI/mainwindow.py: Add "..." to menu items that will open
1212     new dialogs.
1213    
1214     * Thuban/UI/projdialog.py (ProjFrame.__init__): Rearrange the
1215     order that the controls are created so that tabbing works correctly.
1216     (ProjFrame.OnApply): Renamed from _OnTry() to use wxDialog behaviour.
1217     (ProjFrame.OnOK): Renamed from _OnOK() to use wxDialog behaviour.
1218     (ProjFrame.OnCancel): Renamed from _OnClose() to use wxDialog behaviour.
1219     (ProjPanel.__init__): Add "Airy" to the list of ellipsoids so we
1220     can provide the "UK National Grid" as a default projection.
1221     (UTMPanel.__init__): Rearrange the order that the controls are
1222     created so that tabbing works correctly.
1223    
1224 bh 809 2003-05-05 Bernhard Herzog <[email protected]>
1225    
1226 bh 811 * extensions/thuban/wxproj.cpp: Fix some of the comments.
1227     (project_point): If a map projection but no layer projection is
1228     given, convert degrees to radians before applying the map
1229     projection.
1230    
1231 bh 809 * Thuban/UI/tableview.py (TableGrid.disallow_messages)
1232     (TableGrid.allow_messages): New methods to make it possible to
1233     inhibit message sending.
1234     (TableGrid.issue): Only send the message if not inhibited.
1235     (LayerTableGrid.select_shape): Use the new methods to make sure
1236     that no ROW_SELECTED message is sent while we're updating the
1237     selected rows to match the selected shapes.

1241     Implementation of MemoryTable.
1242    
1243     * Thuban/Model/table.py (MemoryTable): New. Quite simple table
1244     implementation that operates on a list of tuples. All of the data
1245     are kept in the memory.
1246    
1247     * test/test_table.py (MemoryTableTest): New.
1248    
1249     * test/test_transientdb.py (SimpleTable): Removed.
1250     (TestTransientTable.test_transient_joined_table,

1255    
1256 jonathan 803 * Data/iceland_sample.thuban: Now contains correct projections
1257     for each of the layers.
1258    
1259     * Resources/Projections/defaults.proj: Geographic projection
1260     contains unit conversion parameter.
1261    
1262     2003-04-30 Jonathan Coles <[email protected]>
1263    
1264 jonathan 793 The most important part of this putback is the projection changes.
1265     It should now be possible to specify the projection that a layer
1266     is in and then specify a different projection for the map. The
1267     projection dialog has an extra parameter for a geographic projection
1268     which lets the user select if the input is in degrees or radians.
1269    
1270     * Thuban/Model/layer.py (Layer.ShapesInRegion): Fix docstring
1271     to say that the parameter is a tuple of unprojected
1272     points (which is what the callers to this method were assuming).
1273     Also, since the points are unprojected we need to projected them.
1274    
1275     * Thuban/UI/legend.py (LegendTree.MoveCurrentItemUp,
1276     LegendTree.MoveCurrentItemDown): If the layer or any of the layer's
1277     groups are selected, move the layer up/down. Fixes RTbug #1833.
1278    
1279     * Thuban/UI/mainwindow.py: Move menu item map_rename up.
1280    
1281     * Thuban/UI/projdialog.py (ProjFrame._OnSave): Add missing
1282     parameter in call to SetClientData.
1283     (GeoPanel): Add support for selecting the units that the
1284     source data is in (Radians or Degrees).
1285    
1286     * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Optimize
1287     the rendering loop by reducing the number of if's, removing the
1288     unnecessary try/except block, and checking if the old group
1289     is the same as the new one (which happens a lot if there is
1290     no classification, or lots of shapes are in the same group).
1291    
1292     * Thuban/UI/view.py (MapCanvas.OnPaint): Add a try/except block
1293     around the redraw routine to try to catch problems that the user
1294     may create by selecting invalid projections for the data set and
1295     map. Clears the display if there are any problems and prints the
1296     error.
1297     (MapCanvas.do_redraw): Use DC.Clear() instead of drawing a filled
1298     rectangle.
1299    
1300     * extensions/thuban/wxproj.cpp (project_point): First invert the
1301     supplied point (which should be in projected coordinates) using
1302     the layer's projection and then project the point using the
1303     map's projection.
1304     (project_points): Use project_point() to project each point.
1305    
1306 jan 792 2003-04-30 Jan-Oliver Wagner <[email protected]>
1307    
1308     * Thuban/Model/layer.py (Layer.SetShapeStore): Fixed a bug:
1309     don't set the Classification to None if the classfication field
1310     is None (ie only a DEFAULT).
1311

1315    
1316 bh 788 * Thuban/UI/mainwindow.py (MainWindow.identify_view_on_demand): Do
1317     not pop up the dialog if the selection becomes empty (this could
1318     happen if e.g. a new selection is opened while the identify tool
1319     is active and dialog had been closed)
1320

1324     instance variable read_record_last_result
1325     (TransientTableBase.read_record): Make sure reading the same

1333 jonathan 793 2003-04-29 Jonathan Coles <[email protected]>
1334    
1335     * Thuban/common.py: Removed. No longer needed Str2Num. RTbug #1832.
1336    
1337     * Thuban/UI/classgen.py: Remove all uses of Str2Num.
1338    
1339     * Thuban/UI/classifier.py: Remove all uses of Str2Num.
1340     (ClassTable.SetValueAsCustom): Rename keyword argument in
1341     ClassGroup* constructors to match argument name.
1342    
1343 bh 779 2003-04-29 Bernhard Herzog <[email protected]>
1344    
1345     * Thuban/Model/session.py (Session.Destroy): Explicitly close the
1346     transient DB if it exists to make sure it doesn't leave a journal
1347     file in the temp directory.
1348    
1349     * Thuban/Model/transientdb.py (TransientDatabase.close): Set
1350     self.conn to None after closing the connection to make sure it's
1351     not closed twice
1352    
1353 jonathan 767 2003-04-29 Jonathan Coles <[email protected]>
1354    
1355 jonathan 769 Add a visible parameter in the layer XML tag. The default value is
1356     "true". If anything other than "false" is specified we also assume
1357 jonathan 776 "true". Addresses RTbug #1025.
1358 jonathan 769
1359     * Doc/thuban.dtd: Add visible parameter to a layer.
1360    
1361     * Thuban/Model/layer.py (BaseLayer.__init__): Change default value
1362     of visible from 1 to True.
1363     (Layer.__init__): Change default value of visible from 1 to True.
1364    
1365     * Thuban/Model/load.py (SessionLoader.start_layer): Read visible
1366     parameter.
1367    
1368     * Thuban/Model/save.py (SessionSaver.write_layer): Save visible
1369     parameter.
1370    
1371     * test/test_load.py: Add new test data contents_test_visible.
1372     (LoadSessionTest.setUp): save test data.

1374     is loaded correctly.
1375    
1376     * test/test_save.py (SaveSessionTest.testSingleLayer): Add test
1377     for saving an invisible layer.
1378    
1379     2003-04-29 Jonathan Coles <[email protected]>
1380    
1381 jonathan 767 * Thuban/UI/mainwindow.py (MainWindow.SetMap): Look up the
1382     legend dialog box and tell it to change its map to the one
1383     supplied to SetMap(). Fixes RTbug #1770.
1384    
1385 bh 764 2003-04-29 Bernhard Herzog <[email protected]>
1386    
1387 bh 766 Next step of table implementation. Introduce a transient database
1388     using SQLite that some of the data is copied to on demand. This
1389     allows us to do joins and other operations that require an index
1390     for good performance with reasonable efficiency. Thuban now needs
1391     SQLite 2.8.0 and pysqlite 0.4.1. Older versions may work but I
1392     haven't tested that.
1393    
1394     * Thuban/Model/transientdb.py: New. Transient database
1395     implementation.
1396    
1397     * test/test_transientdb.py: New. Tests for the transient DB
1398     classes.
1399    
1400     * Thuban/Model/session.py (AutoRemoveFile, AutoRemoveDir): New
1401     classes to help automatically remove temporary files and
1402     directories.
1403     (Session.__init__): New instance variables temp_dir for the
1404     temporary directory and transient_db for the SQLite database
1405     (Session.temp_directory): New. Create a temporary directory if not
1406     yet done and return its name. Use AutoRemoveDir to have it
1407     automatically deleted
1408     (Session.TransientDB): Instantiate the transient database if not
1409     done yet and return it.
1410    
1411     * Thuban/Model/data.py (ShapefileStore.__init__): Use an
1412     AutoTransientTable so that data is copied to the transient DB on
1413     demand.
1414     (SimpleStore): New class that simply combines a table and a
1415     shapefile
1416    
1417     * Thuban/Model/table.py (Table, DBFTable): Rename Table into
1418     DBFTable and update its doc-string to reflect the fact that this
1419     is only the table interface to a DBF file. Table is now an alias
1420     for DBFTable for temporary backwards compatibility.
1421    
1422     * Thuban/UI/application.py (ThubanApplication.OnExit): Make sure
1423     the last reference to the session goes away so that the temporary
1424     files are removed properly.
1425    
1426     * test/test_load.py (LoadSessionTest.tearDown): Remove the
1427     reference to the session to make sure the temporary files are
1428     removed.
1429    
1430     2003-04-29 Bernhard Herzog <[email protected]>
1431    
1432 bh 764 * Thuban/Model/load.py (XMLReader.__init__, XMLReader.read): Turn
1433     the __parser instance variable into a normal local variable in
1434     read. It's only used there and read will never be called more than
1435     once. Plus it introduces a reference cycle that keeps can keep the
1436     session object alive for a long time.
1437    
1438 jonathan 767 2003-04-29 Jonathan Coles <[email protected]>
1439 jonathan 735
1440 jonathan 762 * Thuban/Model/proj.py (Projection): Removed Set*() methods to make
1441     Projection an immutable item. Fixes RTbug #1825.
1442     (Projection.__init__): Initialize instance variables here.
1443     (ProjFile.Replace): New. Replace the given projection object with
1444     the new projection object. This solves the problem of needing the
1445     mutator Projection.SetProjection() in the ProjFrame class and
1446     allows a projection to change parameters without changing its
1447     location in the file.
1448    
1449     * Thuban/UI/mainwindow.py (MainWindow.SaveSessionAs): Dialog should
1450     be of type wxSAVE and should verify overwriting a file.
1451    
1452     * Thuban/UI/projdialog.py (ProjFrame._OnSave): Use the new
1453     ProjFile.Replace() method instead of the mutator
1454     Projection.SetProjection(). Also requires that we reassign the
1455     client data to the new projection.
1456    
1457     * test/test_proj.py (TestProjection.test): Test GetName() and
1458     GetAllParameters()
1459     (TestProjFile.test): Remove tests for Set*() methods. Add tests
1460     for Replace().
1461    
1462     2003-04-25 Jonathan Coles <[email protected]>
1463    
1464 jonathan 756 * Thuban/Model/save.py (SessionSaver.write_projection): Make sure
1465     to save the name of the projection.
1466    
1467     * test/test_save.py (SaveSessionTest.testLayerProjection): New
1468     test to verify layer projections are saved correctly.
1469    
1470     2003-04-25 Jonathan Coles <[email protected]>
1471    
1472 jonathan 753 * Thuban/Model/proj.py (Projection.SetName): Set the name
1473     to "Unknown" if name is None.
1474     (Projection.SetAllParameters): New. Set the projection's
1475     parameter list to the one supplied.
1476     (Projection.SetProjection): New. Set the projection's
1477     properties to those of the supplied Projection.
1478    
1479     * Thuban/UI/mainwindow.py (MainWindow.MapProjection): Set
1480     the dialog title to include the map's title.
1481     (MainWindow.LayerProjection): Set the dialog title to include
1482     the layer's title.
1483    
1484     * Thuban/UI/projdialog.py (ProjFrame.__ShowError): Consolidate
1485     error dialogs into a single method call.
1486     (ProjFrame.__VerifyButtons): Add more states to check.
1487     (ProjFrame.__GetProjection): Return the current state of an
1488     edited projection or None.
1489     (ProjFrame.__FillAvailList): Remove checks for states that
1490     shouldn't exist.
1491     (ProjFrame._OnNew): Clear all selected items and supply
1492     a projection panel if necessary.
1493    
1494     * test/test_proj.py (TestProjFile.test): Add tests for
1495     ProjFile.SetAllParameters, ProjFile.SetProjection,
1496     ProjFile.SetName.
1497    
1498     2003-04-25 Jonathan Coles <[email protected]>
1499    
1500 jonathan 748 * Thuban/UI/projdialog.py (ProjFrame.__FillAvailList): Now
1501     takes an optional argument to select the current projection.
1502     This does not guarantee that the item is visible due to
1503     limited wxWindows functionality. Fixes RTBug #1821.
1504    
1505     2003-04-25 Jonathan Coles <[email protected]>
1506    
1507 jonathan 743 * Thuban/Model/load.py (SessionLoader.start_projection): Remember
1508     the projection name and use it when constructing the Projection
1509     object.
1510    
1511     * Thuban/Model/proj.py (Projection.__init__): Change the default
1512     value for 'name' to None and then test if name is equal to None
1513     in the body of the constructor. This way the caller doesn't have to
1514     know what the default value should be. Namely, useful in load.py
1515     where we have to pick a default value if the 'name' parameter
1516     doesn't exist in the XML file.
1517    
1518     * test/test_load.py (LoadSessionTest.testLayerProjection): New.
1519     Tests a file where a layer has a projection.
1520    
1521     2003-04-25 Jonathan Coles <[email protected]>
1522    
1523 jonathan 735 * Thuban/Model/layer.py (Layer.TreeInfo): Add an item to the
1524     tree for projection information.
1525    
1526     * Thuban/Model/load.py (XMLReader.GetFilename): Renamed from
1527     XMLReader.GetFileName.
1528     (SessionLoader): Added support for loading projection tags that
1529     appear inside a layer.
1530    
1531     * Thuban/Model/proj.py (ProjFile): Document the class. Move
1532     back to using a list because the order of the projections in
1533     the file is important to maintain. Fixes RTbug #1817.
1534    
1535     * Thuban/Model/resource.py: Rename calls to ProjFile.GetFileName
1536     to ProjFile.GetFilename.
1537    
1538     * Thuban/Model/save.py (SessionSaver.write_layer): Save projection
1539     information.
1540    
1541     * Thuban/UI/projdialog.py (ProjFrame._OnAddToList): Renamed from
1542     ProjFrame._OnSaveAs. Removed old dead code from previous
1543     implementation.
1544     (ProjFrame._OnExport): Add support for exporting more than one
1545     projection to a single file.
1546     (ProjFrame.__FillAvailList): use string formatting (% operator)
1547     to build strings that are (partly) translated. Fixes RTbug #1818.
1548    
1549     * test/test_proj.py (TestProjFile.test): New. Tests the base ProjFile
1550     class.
1551    
1552 bh 734 2003-04-24 Bernhard Herzog <[email protected]>
1553    
1554     * po/es.po: Updated Spanish translation by Daniel Calvelo Aros
1555    
1556     * po/fr.po: New. French translation by Daniel Calvelo Aros
1557    
1558     * Thuban/UI/projdialog.py (ProjFrame._OnSaveAs): Don't translate
1559     empty strings.
1560    
1561 jonathan 735 2003-04-24 Jonathan Coles <[email protected]>
1562 jonathan 724
1563     * Thuban/Model/layer.py (Layer.GetProjection): New. Needed to
1564     implement the interface that the ProjFrame dialog expects.
1565    
1566     * Thuban/Model/proj.py (Projection.SetName): New. Allows the
1567     name of the projection to be changed.
1568     (ProjFile): Use a dictionary instead of a list so that removing
1569     projections is easier and we are sure about uniqueness.
1570     (ProjFile.Remove): Remove the given projection object.
1571    
1572     * Thuban/Model/resource.py (GetSystemProjFiles, GetUserProjFiles):
1573     Return a list with only one projection file instead of searching for
1574     any projection file. This simplifies many things if the user can
1575     only have one system file and one user file.
1576    
1577     * Thuban/UI/classgen.py: Change all references to
1578     genCombo to genChoice.
1579    
1580     * Thuban/UI/mainwindow.py: Add a Projection option under the
1581     layer menu.
1582     (MainWindow.LayerProjection): New. Open up a projection window
1583     for a layer.
1584    
1585     * Thuban/UI/projdialog.py: Large changes to how the dialog is
1586     laid out. Use three panels instead of one. One for the list of
1587     projections, one for the edit controls, and one for the buttons.
1588     Fixed resizing problems so that the dialog resizes correctly
1589     when the projection panel changes. Added import/export, save, and
1590     new buttons/functionality.
1591    
1592 bh 723 2003-04-24 Bernhard Herzog <[email protected]>
1593    
1594     First step towards table management. Introduce a simple data
1595     abstraction so that we replace the data a layer uses more easily
1596     in the next step.
1597    
1598     * Thuban/Model/data.py: New file with a simple data abstraction
1599     that bundles shapefile and dbffile into one object.
1600    
1601     * Thuban/Model/session.py (Session.OpenShapefile): New method to
1602     open shapefiles and return a shape store object
1603    
1604     * Thuban/Model/layer.py (Layer.__init__): Pass the data as a store
1605     object instead of a shapefile filename. This introduces a new
1606     instance variable store holding the datastore. For intermediate
1607     backwards compatibility keep the old instance variables.
1608     (open_shapefile): Removed. No longer needed with the shape store.
1609     (Layer.SetShapeStore, Layer.ShapeStore): New methods to set and
1610     get the shape store used by a layer.
1611     (Layer.Destroy): No need to explicitly destroy the shapefile or
1612     table anymore.
1613    
1614     * Thuban/UI/mainwindow.py (MainWindow.AddLayer)
1615     (MainWindow.AddLayer): Use the session's OpenShapefile method to
1616     open shapefiles
1617    
1618     * Thuban/Model/load.py (ProcessSession.start_layer): Use the
1619     session's OpenShapefile method to open shapefiles
1620    
1621     * test/test_classification.py
1622     (TestClassification.test_classification): Use the session's
1623     OpenShapefile method to open shapefiles and build the filename in
1624     a more platform independed way
1625    
1626     * test/test_layer.py (TestLayer.setUp, TestLayer.tearDown):
1627     Implement to have a session to use in the tests
1628     (TestLayer.test_arc_layer, TestLayer.test_polygon_layer)
1629     (TestLayer.test_point_layer, TestLayer.test_empty_layer): Use the
1630     session's OpenShapefile method to open shapefiles
1631     (TestLayerLegend.setUp): Instantiate a session so that we can use
1632     it to open shapefiles.
1633     (TestLayerLegend.tearDown): Make sure that all references to
1634     layers and session are removed otherwise we may get a resource
1635     leak
1636    
1637     * test/test_map.py (TestMapAddLayer.test_add_layer)
1638     (TestMapWithContents.setUp): Instantiate a session so that we can
1639     use it to open shapefiles.
1640     (TestMapWithContents.tearDown): Make sure that all references to
1641     layers, maps and sessions are removed otherwise we may get a
1642     resource leak
1643     ("__main__"): use support.run_tests() so that more info about
1644     uncollected garbage is printed
1645    
1646     * test/test_save.py (SaveSessionTest.testSingleLayer): Use the
1647     session's OpenShapefile method to open shapefiles
1648     ("__main__"): use support.run_tests() so that more info about
1649     uncollected garbage is printed
1650    
1651     * test/test_selection.py (TestSelection.tearDown): Make sure that
1652     all references to the session and the selection are removed
1653     otherwise we may get a resource leak
1654     (TestSelection.get_layer): Instantiate a session so that we can
1655     use it to open shapefiles.
1656     ("__main__"): use support.run_tests() so that more info about
1657     uncollected garbage is printed
1658    
1659     * test/test_session.py (TestSessionBase.tearDown)
1660     (TestSessionWithContent.tearDown): Make sure that all references
1661     to the session and layers are removed otherwise we may get a
1662     resource leak
1663     (TestSessionWithContent.setUp): Use the session's OpenShapefile
1664     method to open shapefiles
1665    
1666 jonathan 721 2003-04-24 Jonathan Coles <[email protected]>
1667    
1668     * Thuban/Model/load.py (XMLReader.read): Should have been checking
1669     if the file_or_filename object had the 'read' attribute.
1670    
1671 jonathan 715 2003-04-23 Jonathan Coles <[email protected]>
1672    
1673 jonathan 720 * Thuban/Model/resource.py: Fixes RTbug #1813.
1674     (ReadProjFile): Add documentation about which exceptions are raised.
1675     Always pass the exceptions up to the caller.
1676     (GetProjFiles): If the directory can't be read return an empty list.
1677     If any of the proj files can't be read skip that file and go
1678     on to the next one.
1679    
1680     * test/test_proj.py: Added test cases to handle nonexistent files,
1681     unreadable files, and files that don't parse correctly.
1682    
1683     2003-04-23 Jonathan Coles <[email protected]>
1684

1686     of projection templates and optionally edit them and save new ones.
1687    
1688     * Thuban/UI/projdialog.py (ProjFrame): New. Main dialog.
1689     (ProjPanel): Base class for projection specific panels.
1690     (TMPanel): Projection panel for Transverse Mercartor.
1691     (UTMPanel): Projection panel for Universal Transverse Mercartor.
1692     (LCCPanel): Projection panel for Lambert Conic Conformal.
1693     (GeoPanel): Projetion panel for Geographic Projection.
1694    
1695     2003-04-23 Jonathan Coles <[email protected]>
1696    
1697 jonathan 715 * Thuban/Model/load.py (XMLReader): Renamed from XMLProcessor to
1698     promote symmetry. There now exists XMLReader and XMLWriter.
1699     (XMLReader.read): New. Call to read the given file descriptor or
1700     filename.
1701     (XMLReader.close): New. Make sure the file is closed.
1702     (XMLReader.GetFileName): New. Return just the file name that is being
1703     read from.
1704     (XMLReader.GetDirectory): New. Return just the directory of the file
1705     that is being read.
1706     (XMLReader.AddDispatchers): New. Take a dictionary which contains
1707     the names of functions to call as the XML tree is parsed.
1708     (XMLReader.startElementNS): Updated to use new dispatcher dictionary.
1709     (XMLReader.endElementNS): Updated to use new dispatcher dictionary.
1710     (SessionLoader): Removed class variables start_dispatcher and
1711     end_dispatcher since this functionality is now part of a class
1712     instance. Fixes RTbug #1808.
1713     (SessionLoader.__init__): Add dispatcher functions.
1714     (load_xmlfile): Code was moved into the XMLReader.read().
1715     (load_session): Use modified SessionLoader.
1716    
1717     * Thuban/Model/map.py (Map.GetProjection): New. Returns the
1718     map's projection.
1719    
1720     * Thuban/Model/proj.py (Projection.GetParameters): Renamed to

1722     (Projection.GetParameter): Returns the value for the given parameter.
1723    
1724     * Thuban/Model/resource.py: Use XMLReader and XMLWriter.
1725     (GetProjFiles): Renamed from GetProjections. Now returns a list
1726     of ProjFile objects.

1728     a list of ProjFile objects whose files are not user defined.
1729     (GetUserProjFiles): Renamed from GetUserProjections. Returns a
1730     list of ProjFile objects whose files are user defined.
1731     (ProjFileReader): Extend new XMLReader.
1732    
1733     * Thuban/Model/save.py (XMLWriter): Renamed from XMLSaver to
1734     promote symmetry.
1735    
1736     * Thuban/UI/classgen.py (ClassGenDialog.__init__): Use a wxChoice
1737     control instead of a wxComboBox. wxChoice controls do not generate
1738     events as the uses highlights possible choices which fixes problems
1739     with resizing the dialog when the use selects an option.
1740    
1741     * Thuban/UI/classifier.py (Classifier.__init__): Use a wxChoice
1742     control instead of a wxComboBox.
1743    
1744     * Thuban/UI/mainwindow.py (MainWindow.Projection): Use new projection
1745     dialog.

1753     constants
1754    
1755 bh 703 * Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape)
1756     (IdentifyGridCtrl.selected_shape): Use table, not shapetable.
1757    
1758 bh 700 2003-04-17 Bernhard Herzog <[email protected]>
1759    
1760 bh 701 * Thuban/Model/layer.py: Don't import LAYER_LEGEND_CHANGED.
1761     (Layer): Update doc-string since LAYER_LEGEND_CHANGED is not used
1762     anymore.
1763     (Layer.BoundingBox, Layer.GetFieldType, Layer.NumShapes)
1764     (Layer.ShapeType, Layer.Shape): No need to call
1765     self.open_shapefile since it's always called in __init__
1766    
1767 bh 700 * Thuban/UI/application.py (ThubanApplication.MainLoop): Removed.
1768     In wxPython 2.4 there's no need to extend MainLoop anymore since
1769     wxPython itself makes sure OnExit is called.

1772    
1773 jonathan 693 Initial putback of projection management code. Includes new
1774     classes to read and write projection files. The current load
1775     and save classes were abstracted a bit so they could be reused.
1776     The Projection class was extended to provide new methods and
1777     have a name.
1778    
1779     * Thuban/Model/load.py (XMLProcessor): New. Contains all the
1780     general XML reading methods that were part of ProcessSession.
1781    
1782     * Thuban/Model/proj.py (Projection.__init__): Accepts an optional
1783     name.
1784     (ProjFile): New. Represents a file that contains projection
1785     information.

1788     for read and writing projection files.
1789    
1790     * Thuban/Model/save.py (XMLSaver): New. Contains all the
1791     general XML writing methods that were part of SessionSaver.
1792     (SessionSaver): Renamed from Saver.
1793    
1794     * test/test_proj.py: New test cases for the projection
1795     file read and write functions.
1796    
1797     2003-04-16 Jonathan Coles <[email protected]>
1798    
1799 jonathan 688 * Thuban/Model/classification.py: Use repr() around values
1800     in the ClassGroup*.__repr__() methods so it is clearer when
1801     a value is a string and when it is a number.
1802    
1803     * test/test_load.py: Rework the classification test to test
1804     that we can load old files.
1805     (testLabels): Test a file where the groups have labels.
1806    
1807 bh 687 2003-04-16 Bernhard Herzog <[email protected]>
1808    
1809     Safer implementation of the performance enhancements of the
1810     low-level renderer:
1811    
1812     * extensions/thuban/wxproj.cpp (extract_projection)
1813     (extract_pointer): Rename extract_projection to extract_pointer
1814     and redefine its purpose to return the pointer stored in a CObject
1815     returned by the object's cobject method. Update all callers.
1816     (s_draw_info, free_draw_info, draw_polygon_init): Implement the
1817     handling of these low-level parameters so that each s_draw_info
1818     instance is handled as a CObject at python level that also
1819     contains real references to the actual python objects which
1820     contain the values in the struct. Add free_draw_info as the
1821     destructor.
1822     (draw_polygon_shape): Add the py_draw_info parameter which must a
1823     cobject containing an s_draw_info pointer.
1824    
1825     * Thuban/UI/renderer.py (MapRenderer.polygon_render_param): New
1826     method to instantiat the low-level render parameter
1827     (MapRenderer.draw_shape_layer): Use the new method. Remove some
1828     commented out code.
1829     (MapRenderer.draw_polygon_shape): Make the first parameter not the
1830     layer but the low-level render parameter
1831     (ScreenRenderer.draw_shape_layer): Use the low-level render
1832     parameter.
1833    
1834 jonathan 673 2003-04-15 Jonathan Coles <[email protected]>
1835    
1836 jonathan 680 * Thuban/Model/classification.py: Implemented __repr__ for
1837     the ClassGroup* classes to make debugging a bit easier.
1838     (ClassGroup.SetLabel): Check that the string is an instance
1839     of StringTypes not StringType. Accounts for Unicode strings.
1840    
1841     * Thuban/Model/color.py: Implemented __repr__ to make
1842     debugging a bit easier.
1843    
1844     * Thuban/Model/save.py (Saver.write_classification): Need to
1845     save the group label.
1846    
1847     * test/test_load.py (testClassification): New. Loads the
1848     iceland_sample_test.thuban file and checks if it was loaded
1849     correctly.
1850    
1851     2003-04-15 Jonathan Coles <[email protected]>
1852    
1853 jonathan 673 * extensions/thuban/wxproj.cpp (draw_polygon_init): New. Used
1854     to improve rendering performance by initializing the variables
1855     that are not change each time draw_polygon_shape() is called.
1856     The values are stored in a global struct draw_info.
1857     (draw_polygon_shape): Removed initialization code that is
1858     now in draw_polygon_init().
1859    
1860     * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Make
1861 jonathan 674 drawing initialization call to draw_polygon_init()
1862     (MapRenderer.draw_polygon_shape): Use new signature of

1866     weirdness by setting the range to (1, maxint).
1867 jonathan 673
1868 jonathan 674 * Thuban/Model/classification.py (ClassGroupProperties): Make
1869     instance variables private and optimize comparison operator
1870     by first checking if the color references are the same.
1871     (ClassGroupSingleton): Make instance variables private.
1872     (ClassGroupRange): Make instance variables private.
1873 jonathan 673
1874 jonathan 674 * HOWTO-Release: Filled in missing steps for releasing packages.
1875    
1876 bh 672 2003-04-15 Bernhard Herzog <[email protected]>

1900    
1901     * README: Add note about the translations when building from CVS
1902    
1903 jonathan 669 2003-04-14 Jonathan Coles <[email protected]>
1904    
1905     * Thuban/UI/dock.py: Fixes some window resizing problems most
1906     noticable under windows. Always assume the button bitmaps will
1907     be there. Code clean up.

1909     images for the dock/undock button to the same images.
1910     Work around for RTbug #1801.
1911    
1912     * Thuban/UI/legend.py (LegendPanel.__init__): The toolbar should

1923    
1924     * Thuban/UI/legend.py (LegendPanel.__init__): Call Create() to
1925     finalize the intialization of the panel.
1926    
1927     * Thuban/UI/dock.py (DockPanel.Create): New. Finalizes the
1928     creation of the panel. Should be the last thing called in the
1929     initializer of a subclass.
1930    
1931     * Thuban/UI/classgen.py (ClassGenDialog.__init__): Actively
1932     set the current selections in the combo boxes. This is needed

1961     * Thuban/UI/classifier.py: Refactored ID's from ID_CLASSIFY_* to
1962     ID_PROPERTY_*.
1963     (Classifier.__init__): Minor changes to the layout.

1975     (MainWindow): Use new resource class to import bitmaps.
1976    
1977     2003-04-11 Jonathan Coles <[email protected]>
1978    
1979 jonathan 646 * Resources/Bitmaps/close_12.xpm, Resources/Bitmaps/dock_12.xpm,

1989 jonathan 636 2003-04-10 Jonathan Coles <[email protected]>
1990    
1991 jonathan 644 * Thuban/Model/classification.py: (ClassGroupRange.__init__):
1992     Should pass group to ClassGroup constructor.
1993    
1994     2003-04-10 Jonathan Coles <[email protected]>
1995    
1996 jonathan 636 * Thuban/Model/classification.py: (ClassGroup): Move all the common
1997     methods of the derived classes ([Set|Get]Properties(), __eq__, __ne__)
1998     here. Implement SetVisible(), IsVisible().
1999     (ClassGroup.__init__): Add group parameter which acts as a copy
2000     constructor.
2001    
2002     * Thuban/UI/classifier.py (ClassTable): Add a new column for the
2003     "Visible" check boxes.
2004     (Classifier): Rename the buttons and refactor the code to match
2005     the new labels.
2006    
2007     * Thuban/UI/legend.py: Classify button is now called "Properties".
2008     Refactored the code to change variable names.
2009     (LegendTree.__FillTreeLayer): Only list a group if it is visible.
2010    
2011     * Thuban/UI/mainwindow.py: MainWindow.OpenClassifier renamed to
2012     MainWindow.OpenLayerProperties. MainWindow.LayerEditProperties
2013     renamed to MainWindow.LayerEditProperties.
2014     (MainWindow.ToggleLegend): Don't include map name in legend title.
2015     (MainWindow.SetMap): Added the map name to the window title.
2016     (MainWindow.LayerFillColor, MainWindow.LayerTransparentFill,
2017     MainWindow.LayerOutlineColor, MainWindow.LayerNoOutline): Removed.
2018     Functionality is found in the layer properties dialog.
2019    
2020     * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Only
2021     draw visible groups.
2022    
2023 jonathan 626 2003-04-09 Jonathan Coles <[email protected]>
2024    
2025 jonathan 634 * Thuban/UI/classgen.py: Modifications to allow simple
2026     addition and selection of new color schemes.
2027     (MonochromaticRamp): New. Generates a ramp between two colors.
2028     (RedRamp): New. Generates a ramp of all red.
2029     (GreenRamp): New. Generates a ramp of all green.
2030     (BlueRamp): New. Generates a ramp of all blue.
2031    
2032     2003-04-09 Jonathan Coles <[email protected]>
2033    
2034 jonathan 626 * Thuban/Model/classification.py (Classification.__deepcopy__):
2035     Need to copy over field and fieldType attributes.
2036    
2037     * Thuban/Model/table.py (Table.field_range): New. Retrive the
2038     maximum and minimum values over the entire table for a given
2039     field.
2040     (Table.GetUniqueValues): New. Retrieve all the unique values
2041     in the table for a given field.
2042    
2043     * Thuban/UI/classgen.py: Renamed GenRangePanel to GenUniformPanel.
2044     (GenUniquePanel): New. Controls to allow the user to select
2045     which unique field values they would like in the classification.
2046     (CustomRampPanel): Code that was in ClassGenDialog that allows
2047     the user to select the properties for a custom ramp.
2048     (ClassGenerator.GenUniformDistribution): Was called GenerateRanges.
2049    
2050     * Thuban/UI/classifier.py: Removed a lot of debugging code.
2051     (Classifier._SetClassification): Callback method so that the
2052     class generator can set the classification in the grid.
2053     (ClassGroupPropertiesCtrl): New. Encapsulates the drawing and
2054     editing of a group properties class into a wxWindows control.
2055    
2056     * Thuban/UI/dock.py: It was decided that if the user closes
2057     a dockable window the window should simply hide itself. That
2058     way if the user wants to show the dock again it appears in the
2059     same place as it was when it was closed.
2060     (DockableWindow.Destroy): Call renamed method OnDockDestroy().
2061     (DockableWindow._OnButtonClose): Hide the window instead of

2068    
2069     * Thuban/UI/mainwindow.py: Import just the Classifier class.
2070    
2071 bh 623 2003-04-07 Bernhard Herzog <[email protected]>
2072    
2073 bh 625 * Thuban/UI/mainwindow.py (main_menu): Move the toggle_legend item
2074     to the map module
2075    
2076     2003-04-07 Bernhard Herzog <[email protected]>
2077    
2078 bh 623 * Thuban/UI/mainwindow.py (MainWindow.ShowSessionTree): Removed in
2079     favor of ToggleSessionTree
2080     (MainWindow.ToggleSessionTree): New method to toggle visibility of
2081     the session tree.
2082     (MainWindow.SessionTreeShown): New method to return whether the
2083     session tree is currently shown.
2084     (MainWindow.ToggleLegend): New method to toggle visibility of the
2085     legend
2086     (MainWindow.ShowLegend): Implement in terms of ToggleLegend and
2087     LegendShown
2088     (MainWindow.LegendShown): New method to return whether the legend
2089     is currently shown.
2090     (_method_command): Add checked parameter so we can define check
2091     menu items
2092     (_has_tree_window_shown, _has_legend_shown): Use the appropriate
2093     mainwindow methods.
2094     (show_session_tree, show_legend commands): Removed.
2095     (toggle_session_tree, toggle_legend commands): New commands to
2096     toggle the visibility of the dialogs
2097    
2098 jonathan 612 2003-04-07 Jonathan Coles <[email protected]>
2099    
2100 jonathan 619 * Thuban/UI/classgen.py: Fix Windows problem.
2101    
2102     * Thuban/UI/dock.py: Fix Windows problem.
2103    
2104     * Thuban/UI/mainwindow.py: Use False instead of false.
2105     (MainWindow.ShowLegend): Remove unnecessary switch parameter.
2106    
2107     2003-04-07 Jonathan Coles <[email protected]>
2108    
2109 jonathan 612 Since we now say that the order of the groups in a classification
2110     matters, it makes sense to be able to manipulate that order. Most
2111     of the changes to Thuban/Model/classification.py are to that end.
2112    
2113     * Thuban/Model/classification.py (Classification.AppendGroup,
2114     Classification.InsertGroup, Classification.ReplaceGroup,
2115     Classification.RemoveGroup, Classification.GetGroup): Do as the
2116     names imply.
2117     (Classification.FindGroup): This was called GetGroup, but GetGroup
2118     takes an index, while FindGroup takes a value.
2119     (Classification.__deepcopy__): Copy all the groups, BUT NOT THE LAYER
2120     REFERENCE. Currently there is a cyclic reference between the layer
2121     and its classification. If the classification doesn't need to know
2122     its owning layer we can change this, since it may make sense to be
2123     able to use the same classification with different layers.
2124    
2125     * Thuban/Model/load.py: Use Classification.AppendGroup(), not AddGroup()
2126    
2127     * Thuban/UI/classgen.py: Use Classification.AppendGroup(),
2128     not AddGroup()
2129    
2130     * Thuban/UI/classifier.py: Now that we can depend on the order in
2131     a Classification and have methods to manipulate that order we don't
2132     need to use our own data structures in the grid. We can simply make
2133     the grid/table access the information they need from a copy of
2134     the classification object.
2135     (Classifier._OnCloseBtn): Event handler for when the user clicks
2136     'Close'. This is needed so if the user applies changes and then
2137     continues to change the table the user has the option of discarding
2138     the most recent changes and keeping what they applied.
2139    
2140     * Thuban/UI/mainwindow.py: Put "Show Legend" and "Show Session Tree"
2141     into the same group.
2142    
2143     * extensions/thuban/wxproj.cpp (check_version): If Thuban is compiled
2144     with a really old version of proj, PJ_VERSION won't even be defined.
2145     If it isn't defined then just compile so that the function always
2146     returns Py_False.
2147    
2148     * test/test_classification.py: Fix tests to use the renamed methods.
2149     Still need to write tests for the new methods.
2150    
2151 jonathan 601 2003-04-04 Jonathan Coles <[email protected]>
2152 jonathan 608
2153 jonathan 612 * Thuban/UI/classifier.py (Classifier.__SelectField): Move the
2154     call to SetSelection out of the method and before the call
2155     to __SelectField in __init__. This prevents a recursion of events
2156     when _OnFieldSelect is triggered by the user.
2157    
2158     2003-04-04 Jonathan Coles <[email protected]>
2159    
2160 jonathan 608 * Thuban/Model/classification.py: Rename Color.None to
2161     Color.Transparent.
2162     (ClassGroupProperties.SetLineColori, ClassGroupProperties.SetFill):
2163     Don't bother copying the color, since Colors are immutable.
2164    
2165     * Thuban/Model/color.py, Thuban/Model/layer.py, Thuban/Model/load.py,
2166     Thuban/UI/classifier.py, Thuban/UI/mainwindow.py,
2167     Thuban/UI/renderer.py, Thuban/UI/view.py:
2168     Rename Color.None to Color.Transparent.
2169    
2170     * test/test_classification.py, test/test_load.py: Rename Color.None
2171     to Color.Transparent.
2172    
2173     2003-04-04 Jonathan Coles <[email protected]>
2174 jonathan 603
2175     * Thuban/Model/classification.py: Fix assert calls.
2176     (ClassGroupProperties.SetLineColor, ClassGroupProperties.SetFill):
2177     Copy the color parameter rather than hold onto a reference.
2178 jonathan 601
2179 jonathan 603 * Thuban/Model/color.py (Color.__copy__, Color.__deepcopy): Copy
2180     the color object.
2181     (NoColor.__copy__, NoColor.__deepcopy): Return 'self' so that we
2182     are sure there exists only one refernce to Color.None in the system.

2300     group within the grid when the classification dialog is opened.
2301     Also contains a lot of debugging printouts which will later
2302     be removed.
2303    
2304     * Thuban/UI/dock.py: Complete rework on the dock code so that
2305     that it is fairly removed from the rest of the Thuban application.
2306     It is easy to add new docks which the rest of the program having
2307     to be aware of them.
2308    
2309     * Thuban/UI/legend.py: Modifications to support selecting a
2310     specific group in the classification dialog. Changed how layers
2311     are drawn when the layer is visible/invisible.
2312

2329     2003-03-26 Jonathan Coles <[email protected]>
2330    
2331 jonathan 557 This putback contains the code for dockable windows. There is
2332     no support in wxWindows as of this date for windows that can
2333     attach themselves to other windows.
2334    
2335     The current model contains a DockableWindow which has a parent
2336     window for when it is detached and a dock window that it puts
2337     its contents in when it is docked. The contents of a DockableWindow
2338     must be a DockPanel. DockPanel itself derives from wxPanel.

2348    
2349     * Thuban/UI/dock.py: New. Classes for the DockPanel and
2350     DockableWindow.
2351

2358     LegendPanel as the contents.
2359    
2360     * Thuban/UI/messages.py: Added DOCKABLE_* messages
2361

2375    
2376     * Thuban/UI/legend.py: New. Creates a window that shows the map's
2377     Legend information and allows the user to add/modify classifications
2378     and how the layers are drawn on the map.
2379    
2380     * setup.py: New command 'build_docs' which currently uses
2381     happydoc to generate html documentation for Thuban.
2382    
2383     * Thuban/Model/classification.py (ClassGroup.GetDisplayText): New.
2384     Returns a string which is appropriately describes the group.
2385    
2386     * Thuban/Model/layer.py (Layer.SetClassification): Generate a
2387     LAYER_CHANGED event instead of a LAYER_LEGEND_CHANGED event.
2388    
2389     * Thuban/Model/map.py (Map): Rename messages and use new, more
2390     specific, messages.
2391    
2392     * Thuban/Model/messages.py: New message to indicate that a layer's
2393     data has changed (LAYER_CHANGED). New map messages to indicate
2394     when layers have been added/removed/changed or if the stacking order
2395     of the layers has changed.
2396    
2397     * Thuban/Model/session.py: Rename and use new messages.
2398    
2399     * Thuban/UI/classifier.py: Remember if any changes have actually
2400     been applied so that if the dialog is cancelled without an application
2401     of changes we don't have to set a new classification.
2402     (ClassDataPreviewer): Pulled out the window specific code and put it
2403     ClassDataPreviewWindow. ClassDataPreviewer can then be used to draw
2404     symbols on any DC.
2405    
2406     * Thuban/UI/mainwindow.py: New code to open the legend.
2407    
2408     * Thuban/UI/view.py: Use new message names.

2413     of Python, wxPython, and some other libraries.
2414    
2415     * extensions/thuban/wxproj.cpp (check_version): Checks the given
2416     version against what wxproj was compiled with.

2424     script
2425    
2426     2003-03-14 Bernhard Herzog <[email protected]>
2427    
2428     Implement selection of multiple selected shapes in the same layer:
2429    
2430     - Introduce a new class to hold the selection. This basically
2431     replaces the interactor which was nothing more than the
2432     selection anyway. A major difference is of course that the new
2433     selection class supports multiple selected shapes in one layer
2434    
2435     - Move the object that represents the selection from the
2436     application to the canvas. The canvas is a better place than the
2437     application because the selection represents which shapes and
2438     layer of the map displayed by the canvas are selected and
2439     affects how the map is drawn.
2440    
2441     - Make the selection and its messages publicly available through
2442     the mainwindow.
2443    
2444     - The non-modal dialogs do not get a reference to the interactor
2445     anymore as they can simply refer to their parent, the
2446     mainwindow, for the what the interactor had to offer.
2447    
2448     * Thuban/UI/selection.py: New module with a class to represent the
2449     selection.
2450    
2451     * Thuban/UI/messages.py (SELECTED_TABLE, SELECTED_MAP): Remove
2452     these unused messages
2453    
2454     * Thuban/UI/application.py (ThubanApplication.OnInit)
2455     (ThubanApplication.OnExit, ThubanApplication.SetSession): The
2456     interactor is gone now.
2457     (ThubanApplication.CreateMainWindow): There is no interactor
2458     anymore so we pass None as the interactor argument for now for
2459     compatibility.
2460    
2461     * Thuban/UI/view.py (MapCanvas.delegated_messages)
2462     (MapCanvas.Subscribe, MapCanvas.Unsubscribe): In Subscribe and
2463     Unsubscribe, delegate messages according to the delegated_messages
2464     class variable.
2465     (MapCanvas.__getattr__, MapCanvas.delegated_methods): Get some
2466     attributes from instance variables as described with the
2467     delegated_methods class variable.
2468     (MapCanvas.__init__): New instance variable selection holding the
2469     current selection
2470     (MapCanvas.do_redraw): Deal with multiple selected shapes. Simply
2471     pass them on to the renderer
2472     (MapCanvas.SetMap): Clear the selection when a different map is
2473     selected.
2474     (MapCanvas.shape_selected): Simple force a complete redraw. The
2475     selection class now takes care of only issueing SHAPES_SELECTED
2476     messages when the set of selected shapes actually does change.
2477     (MapCanvas.SelectShapeAt): The selection is now managed in
2478     self.selection
2479    
2480     * Thuban/UI/mainwindow.py (MainWindow.delegated_messages)
2481     (MainWindow.Subscribe, MainWindow.Unsubscribe): In Subscribe and
2482     Unsubscribe, delegate messages according to the delegated_messages
2483     class variable.
2484     (MainWindow.delegated_methods, MainWindow.__getattr__): Get some
2485     attributes from instance variables as described with the
2486     delegated_methods class variable.
2487     (MainWindow.__init__): The interactor as ivar is gone. The
2488     parameter is still there for compatibility. The selection messages
2489     now come from the canvas.
2490     (MainWindow.current_layer, MainWindow.has_selected_layer):
2491     Delegate to the the canvas.
2492     (MainWindow.LayerShowTable, MainWindow.Classify)
2493     (MainWindow.identify_view_on_demand): The dialogs don't need the
2494     interactor parameter anymore.
2495    
2496     * Thuban/UI/tableview.py (TableFrame.__init__)
2497     (LayerTableFrame.__init__, LayerTableFrame.OnClose)
2498     (LayerTableFrame.row_selected): The interactor is gone. It's job
2499     from the dialog's point of view is now done by the mainwindow,
2500     i.e. the parent. Subscribe to SHAPES_SELECTED instead
2501     of SELECTED_SHAPE
2502    
2503     * Thuban/UI/dialogs.py (NonModalDialog.__init__): The interactor
2504     is gone. It's job from the dialog's point of view is now done by
2505     the mainwindow, i.e. the parent.
2506    
2507     * Thuban/UI/classifier.py (Classifier.__init__): The interactor is
2508     gone. It's job from the dialog's point of view is now done by the
2509     mainwindow, i.e. the parent.
2510    
2511     * Thuban/UI/tree.py (SessionTreeView.__init__): The interactor is
2512     gone. It's job from the dialog's point of view is now done by the
2513     mainwindow, i.e. the parent.
2514     (SessionTreeCtrl.__init__): New parameter mainwindow which is
2515     stored as self.mainwindow. The mainwindow is need so that the tree
2516     can still subscribe to the selection messages.
2517     (SessionTreeCtrl.__init__, SessionTreeCtrl.unsubscribe_all)
2518     (SessionTreeCtrl.update_tree, SessionTreeCtrl.OnSelChanged): The
2519     selection is now accessible through the mainwindow. Subscribe to
2520     SHAPES_SELECTED instead of SELECTED_SHAPE
2521    
2522     * Thuban/UI/identifyview.py (IdentifyView.__init__): Use the
2523     SHAPES_SELECTED message now.
2524     (IdentifyView.selected_shape): Now subscribed to SHAPES_SELECTED,
2525     so deal with multiple shapes
2526     (IdentifyView.__init__, IdentifyView.OnClose): The interactor is
2527     gone. It's job from the dialog's point of view is now done by the
2528     mainwindow, i.e. the parent.
2529    
2530     * Thuban/UI/controls.py (RecordListCtrl.fill_list): The second
2531     parameter is now a list of shape ids.
2532     (RecordTable.SetTable): The second parameter is now a list of
2533     indices.
2534    
2535     * Thuban/UI/renderer.py (ScreenRenderer.RenderMap): Rename the
2536     selected_shape parameter and ivar to selected_shapes. It's now a
2537     list of shape ids.
2538     (MapRenderer.draw_label_layer): Deal with multiple selected
2539     shapes. Rearrange the code a bit so that the setup and shape type
2540     distinctions are only executed once.
2541    
2542     * test/test_selection.py: Test cases for the selection class
2543    
2544 jonathan 527 2003-03-11 Jonathan Coles <[email protected]>
2545    
2546     * Thuban/Model/load.py: Temporary fix so that the xml reader
2547     doesn't cause Thuban to crash.
2548    
2549     * Thuban/Model/layer.py: Handle the cyclic references between
2550     a layer and its classification better, and be sure to disconnect
2551     the classification from the layer when the layer is destroyed
2552     so that we don't maintain a cyclic reference that may not be
2553     garbage collected.
2554    
2555     * Thuban/Model/classification.py: See comment for layer.py.
2556    
2557 jan 523 2003-03-12 Jan-Oliver Wagner <[email protected]>

2563    
2564     * Thuban/UI/classifier.py: Add normal border to SelectPropertiesDialog.
2565     Use True instead of true.
2566     (Classifier): Should have a single panel in which all the controls lie.

2580    
2581 jonathan 505 * Thuban/UI/classifier.py (Classifier.__init__): Make the
2582     field type label grow so that when the text changes the
2583     size is updated correctly. This may be a wxWindows bug.
2584    
2585     2003-03-10 Jonathan Coles <[email protected]>
2586    
2587 jonathan 499 * Thuban/UI/application.py: Changed SESSION_CHANGED to
2588     SESSION_REPLACED.
2589    
2590     * Thuban/UI/classifier.py: Wrap text with _().
2591     (ClassGrid.CreateTable): Set dimensions and size hints here,
2592     instead of in Reset, so we only set the size once.
2593    
2594     * Thuban/UI/dialogs.py: Don't need Shutdown(); just use Close()!
2595    
2596     * Thuban/UI/mainwindow.py (MainWindow.prepare_new_session):

2604     2003-03-10 Jonathan Coles <[email protected]>
2605    
2606 jonathan 497 * Thuban/UI/classifier.py (Classifier): SelectField() needed

2609     2003-03-10 Jonathan Coles <[email protected]>
2610    
2611 jonathan 495 * Thuban/UI/classifier.py (Classifier): Use __SelectField()
2612     to correctly set the table information and call this from

2614     is up to date when the dialog opens and when a field is changed.
2615    
2616     2003-03-10 Jonathan Coles <[email protected]>
2617    
2618 jonathan 490 * Thuban/Model/classification.py (Classification): Don't use
2619     layer's message function directly, use the ClassChanged() method
2620     when then classification changes. SetField/SetFieldType/SetLayer
2621     must keep the information about field name and field type in
2622     sync when an owning layer is set or removed.
2623    
2624     * Thuban/Model/layer.py: Added ClassChanged() so that the
2625     classification can tell the layer when its data has changed.
2626     (Layer.SetClassification): Accepts None as an arguement to
2627     remove the current classification and correctly handles
2628     adding a new classification.
2629    
2630     * Thuban/Model/load.py: Comment out print statement
2631    
2632     * test/test_classification.py, test/test_save.py: New and
2633     improved tests.
2634    
2635 jonathan 483 2003-03-07 Jonathan Coles <[email protected]>
2636    
2637     * Thuban/Model/classification.py: Implemented __copy__ and
2638     __deepcopy__ for ClassGroup* and ClassGroupProperites so
2639     they can easily be copied by the classifier dialog.
2640     (ClassGroupProperites.__init__): The default line color should
2641     have been Color.Black.
2642    
2643     * Thuban/UI/classifier.py: Setting and Getting table values now
2644     uses a consistent set of functions.
2645     (Classifier): Now non-modal. Has field type label which changes
2646     as the field changes. Keep track of buttons in a list so that
2647     we can enable/disable the buttons when the None field is selected.
2648     (SelectPropertiesDialog): Add buttons to make the colors transparent.
2649    
2650     * Thuban/UI/dialogs.py (NonModalDialog.Shutdown): New method which
2651     does what OnClose did, but can be called by the application to
2652     close a window. Needed when a session changes, and we have to
2653     close the classifier windows.
2654    
2655     * Thuban/UI/mainwindow.py (MainWindow.prepare_new_session):
2656     Shuts down open dialogs. Used when a new session is created
2657     or a session is opened.
2658     (MainWindow.SaveSession): Should only call application.SaveSession()
2659     if we don't call SaveSessionAs first.
2660     (MainWindow.Classify): Allow different classifier dialogs for
2661     different layers.
2662    
2663     * Thuban/UI/tree.py (SessionTreeView): Remove OnClose and let
2664     the parent class handle it. Add Shutdown() to unsubscibe from
2665     event notification and call the parent Shutdown(). This was
2666     necessary so the application can close the tree window.
2667    
2668 jonathan 478 2003-03-06 Jonathan Coles <[email protected]>
2669    
2670     * Thuban/Model/classification.py: Minor documentation changes,
2671     Addition of __eq__ and __ne__ methods.
2672     (Classification.SetLayer): prevent recursion between this method
2673     and Layer.SetClassification().
2674    
2675     * Thuban/Model/color.py: Addition of __eq__ and __ne__ methods.
2676    
2677     * Thuban/Model/layer.py (SetClassification): prevent recursion
2678     between this method and Classification.SetLayer().
2679    
2680     * test/test_classification.py, test/test_load.py,
2681     test/test_session.py: Fixed and added tests for the classification
2682     classes.
2683    
2684 bh 477 2003-03-06 Bernhard Herzog <[email protected]>
2685    
2686     * Thuban/UI/classifier.py (ClassGrid.__init__)
2687     (ClassGrid.CreateTable): Move the SetSelectionMode call to
2688     CreateTable because otherwise it triggers an assertion in
2689     wxPython/wxGTK 2.4.
2690    
2691 jonathan 459 2003-03-05 Jonathan Coles <[email protected]>
2692    
2693 jonathan 475 * Thuban/common.py: Move FIELDTYPE constants back to table.py.

2704     Fixed RTbug #1713, #1714. Added Move[Up|Down] buttons.
2705     Store just the groups in the table and generate the other
2706     column information when it is requested. Add "None" field
2707     to pull-down to select no classification.
2708    
2709     * Thuban/common.py: Moved FIELDTYPE constants from table.py
2710     (Str2Num): Only catch ValueError exceptions.
2711    
2712     * Thuban/Model/classification.py: Class documentation. Renaming
2713     of methods with Stroke to Line. Groups are stored in a single
2714     list with the default as the first element. Groups are searched
2715     in the order they appear in the list.
2716    
2717     * Thuban/Model/color.py: Documentation.
2718    
2719     * Thuban/Model/layer.py (Layer): Add GetFieldType to retreive
2720     the kind of data represented by a field.

2732    
2733     * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Only
2734     get the layer classification once. Don't try to classify
2735     values when the field is None: just use the default properties.
2736    
2737     * Thuban/UI/view.py: Function name changes.
2738    
2739     * Doc/thuban.dtd: Add field_type attribute to a classification.

2742    
2743 bh 458 * Doc/thuban.dtd: Use correct syntax for optional attributes. Make
2744     the fill and stroke layer attributes optional with suitable
2745     default values. Add the stroke_width layer attribute. Use correct
2746     syntax for empty elements. Make the attribute list for labels
2747     refer to the label element.
2748    
2749     2003-03-04 Bernhard Herzog <[email protected]>
2750    
2751 bh 456 * setup.py (thuban_build_py.build): Add a comment about distutils in
2752     Python 2.3 containing some of the functionality we implement in
2753     setup.py ourselves.
2754    
2755     * Thuban/UI/classifier.py (ClassGrid.__init__): Set the table
2756     before the selection mode. Doing it the other way round triggers
2757     an assertion in wxWindows.
2758    
2759     * Thuban/Model/save.py (escape): Fix typo in doc-string
2760    
2761     * Thuban/Model/classification.py: Remove unnecessary wxPython
2762     import
2763

2765    
2766     * Thuban/Model/classification.py (ClassGroupRange.GetProperties):
2767     Parameter 'value' should default to None.
2768    
2769     * Thuban/UI/mainwindow.py: Use Layer.GetClassification() since
2770     the class attribute __classification is now private.
2771    
2772     * Thuban/UI/classifier.py (ClassGrid): Moved OnCellDClick() from
2773     Classifier to ClassGrid. Added support for removing selected rows,
2774     which including code for keeping track of when cells are selected,
2775     and deselected.
2776     (ClassTable): Support for added/removing rows. Fixed a problem
2777     with __ParseInput whereby it would not allow strings (only numbers)
2778     to be entered.
2779     (Classifier): Added button and supporting code for removing
2780     selected rows.
2781    
2782 jonathan 445 2003-02-27 Jonathan Coles <[email protected]>

2805 jonathan 445 functions. Fix to create a tuple with a single value instead of
2806     simply returning the value.
2807 jonathan 434
2808     * Thuban/UI/renderer.py: Use new Classification and Group functions.
2809     Use common.py functions.

3175     * Thuban/UI/mainwindow.py: Underline the 'x' in "Exit" instead of

3198 bh 302 2002-09-02 Bernhard Herzog <[email protected]>
3199    
3200 bh 304 * Thuban/UI/view.py: Get rid of the idle redraw. This is done by
3201     wxWindows already and our implementation doesn't work correctly
3202     with wxGTK 2.3:
3203     (MapCanvas.__init__): Remove the instance variable
3204     (MapCanvas.OnPaint): Always call do_redraw when there's a map to
3205     be drawin
3206     (MapCanvas.OnIdle): Removed.
3207    
3208 bh 302 * Thuban/UI/view.py (MapCanvas.unprojected_rect_around_point): Add
3209     a parameter to determine the size of the rectangle.
3210     (MapCanvas.find_shape_at): Create the box around the point on a

3214    
3215 bh 292 2002-08-30 Bernhard Herzog <[email protected]>

3243     Handle degenrate rectangles.
3244    
3245 bh 287 * Thuban/Model/table.py: Make writing records work correctly:
3246     (Table.__init__): Keep track of whether the DBF is open for
3247     writing
3248     (Table.write_record): Open the DBF file for writing when necessary
3249

3257

3278    
3279 bh 275 * Thuban/Model/table.py (Table.write_record): New method to write

3293     elsewhere
3294    
3295 bh 269 * Thuban/Model/save.py (Saver): New class to handle serializing a
3296     session into an XML file. The main reason to introduce a class is
3297     that applications built on Thuban can derive from it so that they
3298     can save additional information in a session file.
3299     (save_session): Delegate almost all the work to the Saver class.
3300     Rename the filename argument to file because it may be a file like
3301     object now.
3302    
3303     * Thuban/Model/load.py: Get rid of the Python 1.5.2 compatibility
3304     code. Remove the little test code which would be executed when the
3305     module is run as a script which didn't work anymore since it can't
3306     import the other Thuban modules.
3307     (ProcessSession, load_session): Refactor the ProcessSession to
3308     have one method for each element start and end tag so that derived
3309     classes can easily override the processing of individual tags.
3310     Also, always parse with namespaces enabled because applications
3311     built on top of Thuban will likely use namespaces if they extend
3312     the session file format.
3313    
3314 bh 266 2002-08-21 Bernhard Herzog <[email protected]>
3315    
3316     * setup.py (ThubanInstall.run): Don't repr install_lib_orig
3317     because thubaninit_contents will do it for us.

3327     with self.

3340     instance variable columns
3341     (RecordTable.GetTypeName): row and col may be negative in some
3342     cases.
3343    
3344 bh 254 * setup.py (InstallLocal.initialize_options)
3345     (InstallLocal.finalize_options, InstallLocal.user_options): New
3346     option create-init-file to build a thubaninit.py when running
3347     install_local
3348     (InstallLocal.run): Create the thubaninit.py module when requested
3349     (thubaninit_contents): Split the template into several parts and
3350     create a new function thubaninit_contents that creates the

3353     module.
3354

3365     layers.

3367     inherited Desatroymethod first so that no more messages are
3368     issued.

3370     message if the stacking order actually has changed. Add
3371     doc-strings.

3882    
3883 bh 87 * setup.py: Increment version to 0.1.1
3884    
3885 bh 85 * Thuban/UI/mainwindow.py (MainWindow.__init__): Move the "Add
3886     Layer" and "Remove Layer" commands from the layer menu to the map
3887     menu
3888    
3889 bh 83 2002-02-15 Bernhard Herzog <[email protected]>
3890    
3891     * Thuban/Model/layer.py (Layer.Shape): list append only takes one
3892     argument (python <= 1.5.2 erroneously accepted multiuple
3893     arguments)

3895 bh 81 2002-02-04 Bernhard Herzog <[email protected]>
3896

3901    
3902     * Thuban/UI/controls.py (RecordTable, RecordGridCtrl): New classes
3903     implementing a grid for a single row of a thuban table.
3904    
3905     * Thuban/UI/view.py (MapCanvas.SelectShapeAt): Search through all
3906     layers by default. Easier to use than the previous default of only
3907     searching through the select layer which meant that if no layer
3908     was selected, you couldn't select a shape.
3909    
3910     * Thuban/UI/tableview.py (TableGrid.__init__): Fix typo
3911

3927     * extensions/thuban/wxproj.cpp (project_points): Fix two
3928     off-by-one errors in the last loop that joins the various parts
3929     together.

3951 bh 70 Set the initial selection of the combo boxes to reflect the
3952     projection we're starting with in a way that works on windows,
3953     too.
3954    
3955 bh 64 * Thuban/Lib/connector.py (Connector.print_connections): Print the
3956     puiblisher's ids in hex to make it easier to compare them to the
3957     standard repr of python methods
3958    
3959     * Thuban/Model/map.py (Map.Destroy): Unsubscribe the label_layer
3960     messages
3961    
3962 bh 59 2001-09-13 Bernhard Herzog <[email protected]>
3963    
3964 bh 64 * Thuban/UI/tree.py (SessionTreeCtrl.OnSelChanged): Make sure to
3965     deselect the layer if no layer is selected
3966    
3967 bh 59 * Thuban/UI/view.py (MapCanvas.OnPaint): Only delay drawing to
3968     idle time when there actually is something to draw. If there's
3969     nothing to draw simply clear the window
3970     (MapCanvas.do_redraw): Call dc.EndDrawing and add some comments.
3971     (MapCanvas.SetMap): force a redraw in all cases because

3975     (ZoomOutTool.MouseUp, ZoomInTool.MouseUp): If the mouse wasn't
3976     dragged, zoon in/out by a factor of 2
3977 bh 64 (MapCanvas.find_shape_at): Iterate backwards (i.e. with decreasing
3978     index, i.e. reversed drawing order) so that objects appearing to
3979     be in from of others are selected first. This is probably mostly
3980     relevant for point shapes where the symbols used may overlap
3981 bh 59
3982     * Thuban/Model/session.py (create_empty_session): Unset the
3983     modified bit before returning it
3984

3997    
3998     * setup.py (InnoIconItem): fix typo
3999    
4000     (thuban_bdist_inno.run):
4001     (bdist_inno.run): Move the decision not to create symlinks on
4002     non-nt platforms to thuban_bdist_inno and do it unconditinally
4003     since we never want to create the symlinks here
4004    
4005 bh 48 2001-09-10 Bernhard Herzog <[email protected]>
4006    
4007 bh 53 * Thuban/UI/mainwindow.py (MainWindow.IdentifyTool): Popup the
4008     identify view immediately
4009    
4010     * Thuban/UI/controls.py: New file with two classes RecordListCtrl
4011     and SelectableRecordListCtrl that implement the code shared by the
4012     identify view and the label dialog
4013    
4014     * Thuban/UI/identifyview.py (IdentifyListCtrl): Derive from the
4015     new class RecordListCtrl
4016    
4017     * Thuban/UI/labeldialog.py (LabelDialog.OnOK): Check whether the
4018     return value of GetValue is None instead of using it as a boolean
4019     directly so that Zero numbers are handled properly.
4020     (LabelListCtrl): Derive from the new class
4021     SelectableRecordListCtrl
4022    
4023 bh 48 * Thuban/UI/proj4dialog.py (Proj4Dialog.__init__):
4024     (Proj4Dialog.dialogLayout): Make the window resizable and set the
4025     size of the text control explicitly to make the sizers work on
4026     both Windows and X.
4027    
4028 bh 44 2001-09-07 Bernhard Herzog <[email protected]>
4029    
4030     * Thuban/UI/view.py (MapCanvas.find_shape_at):Add a new parameter
4031     that can limit the search to the currently selected layer.
4032     (MapCanvas.SelectShapeAt): Make sure that the currently selected
4033     layer stays selected even when no shape is found
4034 bh 46 (MapCanvas.FitRectToWindow): If the rect has zero with or zero

4036 bh 44
4037 bh 32 2001-09-06 Bernhard Herzog <[email protected]>
4038    
4039 bh 42 * Thuban/UI/tree.py (SessionTreeCtrl, SessionTreeView.__init__):
4040     Correct the spelling of SessionTreeCtrl. dabbrev is too damn
4041     convenient :-)
4042     (SessionTreeCtrl.__init__, SessionTreeCtrl.update_tree): Introduce
4043     a new instvar layer_to_item to map layers to tree items
4044     (SessionTreeCtrl.layer_selected): Select the appropriate tree item
4045     to match the current selection in the interactor
4046    
4047 bh 40 * Thuban/UI/interactor.py (Interactor.SelectedLayer):
4048     (Interactor.HasSelectedLayer): New methods to query the current

4053     interactor method
4054    
4055     * Thuban/UI/mainwindow.py (MainWindow.__init__):
4056     (MainWindow.LayerShowTable):
4057     (MainWindow.identify_view_on_demand): Store the interactor in an
4058     instvar and use that reference instead of going through main.app
4059    
4060 tkoester 403 * Thuban/UI/mainwindow.py (MainWindow.ShowSessionTree):
4061     * Thuban/UI/application.py (ThubanApplication.OnInit):
4062 bh 40 * Thuban/UI/main.py (main): Create the session tree view in main
4063     with the new mainwindow method ShowSessionTree and not directly
4064     the application's OnInit method
4065    
4066     * Thuban/UI/tree.py (myTreeCtrlPanel):
4067     (SessioinTreeCtrl): Rename to SessioinTreeCtrl and turn it into a
4068     TreeCtrl isntead of a panel. This affects most method since we now
4069     refer to self instead of self.tree
4070     (SessionTreeView): New class implementing a non-modal dialog
4071     showing the session tree.
4072    
4073 bh 35 * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Pass the

4079     (TableGrid.OnSelectCell):
4080     (TableFrame.__init__):
4081     (TableFrame.row_selected):
4082     Selecting rows in the grid view now updates the selected shapes
4083     through the TableFrame. To achieve this we derive TableGrid from
4084     Publisher and introduce the message type ROW_SELECTED which the
4085     TableFrame subscribes to and which is issued by OnRangeSelect and
4086     OnSelectCell
4087    
4088     (DataTable.SelectRow): Removed because it's no longer needed in
4089     the row/shape selection scheme
4090

4092     dialogs
4093    
4094     * Thuban/UI/tableview.py (TableGrid.__init__): Don't subscribe to

4096     parent.
4097     (TableGrid.select_shape): Only update the selection if the shape
4098     is not None.
4099     (TableFrame): Inherit from the new NonModalDialog class.
4100     (TableFrame.__init__, TableFrame.select_shape): Handle the
4101     SELECT_SHAPE message.

4103     SELECT_SHAPE
4104    
4105     * Thuban/UI/mainwindow.py (MainWindow.init_dialogs):
4106     (MainWindow.add_dialog):

4113     management code
4114     (MainWindow.LayerShowTable): maintain separate dialogs for each
4115     table using the non-modal dialog management code to only open a
4116     view once for each table.
4117    
4118     (MainWindow.IdentifyTool):
4119     (MainWindow.__init__):
4120     (MainWindow.identify_view_on_demand): Don't open the identify view
4121     in IdentifyTool anymore. This will be done automatically by the
4122     new method identify_view_on_demand which handles the
4123     SELECTED_SHAPE message so that the identify view will be opened on
4124     demand
4125    
4126     * Thuban/UI/identifyview.py (IdentifyListCtrl.__init__): Remove
4127     the interactor argument. The SELECTED_SHAPE message is now handled
4128     by the parent.
4129     (IdentifyView.__init__): Add the interactor argument so that we
4130     can handle the SELECTED_SHAPE message here
4131     (IdentifyView.selected_shape): New method to handle the
4132     SELECTED_SHAPE messages
4133    
4134     * Thuban/UI/identifyview.py (IdentifyView): Derive from the new
4135     NonModalDialog class
4136     (IdentifyView.OnClose): Extend the inherited version to
4137     unsubscribe SELECT_SHAPE
4138    
4139     * Thuban/Model/session.py (Session.UnsetModified): Remove debug prints
4140    
4141 bh 26 2001-09-05 Bernhard Herzog <[email protected]>

4146     interactor to pass through to the MapCanvas
4147 tkoester 403
4148 bh 26 * Thuban/UI/application.py (ThubanApplication.OnInit): Use the new
4149     argument to the MainWindow constructor to get rid of the ugly hack
4150     that made main.app available early just so that the mapcanvas
4151     could access the interactor object.
4152    
4153 bh 19 2001-09-04 Bernhard Herzog <[email protected]>
4154    
4155 bh 22 * Thuban/UI/mainwindow.py (MainWindow.RunMessageBox): New method
4156     that runs a modal message box
4157     (MainWindow.OnClose): Use the new method
4158     (MainWindow.RemoveLayer): Just do nothing in case no layer is
4159     selected. The command should be grayed out anyway, so there's no
4160     need to pop up a message box.
4161     (MainWindow.AddLayer): Pop up a message box with an error message
4162     if the shape file can't be opened
4163    
4164     * Thuban/Model/layer.py (Layer.__init__): Open the shapefile
4165     immediately. This will cause an exception in case the file can't
4166     be opened and we can display an appropriate message.
4167    
4168 bh 19 * MANIFEST.in: Add extensions/pyprojection/LICENSE
4169    
4170     * setup.py (thuban_bdist_rpm): New class implementing a Thuban
4171     specific bdist_rpm command.

4175     installations.
4176    
4177     * extensions/pyprojection/LICENSE: Copy of the license text in
4178     Projection.i. Having it in a separate file makes it easier to
4179     refer to license text in e.g. RPMs
4180    
4181 bh 18 2001-09-03 Bernhard Herzog <[email protected]>
4182    
4183 bh 19 * setup.py: use wx-config instead of wxgtk-config because it's
4184     more generic
4185    
4186     * setup.py (ThubanInstall.get_outputs): Add the symlink in
4187     <prefix>/bin to the outputs
4188     (ThubanInstall.link_file): New method to link files. We need this
4189     because the standard copy_files refuses to link non-existing
4190     files.
4191     (ThubanInstall.run): Remove the leading install root from the
4192     script filename if an install root was specified and use the new
4193     link_file method
4194 tkoester 403
4195 bh 18 * Thuban/UI/mainwindow.py (MainWindow.AddLayer): Fit the map to
4196     the window when the first layer is added to the map.
4197    
4198     * setup.py (ThubanInstall.run): Honor the build root (self.root)
4199     when linking thuban.py to <prefix>/bin
4200    
4201 bh 16 2001-08-31 Bernhard Herzog <[email protected]>
4202    
4203     * setup.py: In the setup call, the install parameters shouldn't
4204     have trailing slashes because distutils on non-posix platforms
4205     doesn't like that. The same applies to other directories like
4206     "Resources/Bitmaps"
4207    
4208     In the configuration section for nt, move the wxWindows directory
4209     optins into the part clearly marked as editable.
4210    
4211     (InstallLocal.initialize_options):
4212     (InstallLocal.user_options): remove the currently unused debug
4213     flag

4215     works for our case of having packages and modules in one
4216     distribution as well.

4218     (ThubanInstall.finalize_options):
4219     (ThubanInstall.user_options):
4220     (ThubanInstall.boolean_options): Add new options, do-symlink and
4221     extra files. Since these are the first ThubanInstall specific
4222     options, override user_options and boolean_options
4223     (ThubanInstall.run): Honor the new do-symlink and extra-files
4224     options.
4225     (ThubanInstall.get_outputs): Add to override the base-class's
4226     version and add the extra-files to the outputs
4227     (bdist_inno): New class for windows distributions with Inno Setup
4228     (InnoIconItem): Helper class for bdist_inno
4229     (thuban_bdist_inno): Thuban specific version of bdist_inno. Added
4230     this together with the appropriate parameters, to the setup call.
4231 tkoester 403
4232 bh 16 * setup.cfg (bdist_inno): added new section for the inno setup
4233     installer
4234    
4235     * Thuban/UI/tree.py (myTreeCtrlPanel.__init__): New inst var
4236     changing_selection to avoid recursive selection events when
4237     modifying the selection in response to a selection event.
4238     (myTreeCtrlPanel.normalize_selection): Set the new inst var when
4239     changing the tree's selection.
4240     (myTreeCtrlPanel.OnSelChanged): Only normalize the selection when

4244     event.Check only if the command is actuall checkable.
4245     (MainWindow.__init__): Call the toolbar's Realize method to make
4246     sure that the items are actually shown
4247
