183            to a layer.
184    
185            * Thuban/UI/mainwindow.py (MainWindow.TableShow): A very coarse
186            implementation that still needs work.

225            in all occurences.
226    
227            * Thuban/Model/transientdb.py (TransientJoinedTable.__doc__):
228            Typo fixed.
229    
230    2003-05-22  Bernhard Herzog  <[email protected]>
231    
232            Give the tables titles so that the GUI can display more meaningful

402    2003-05-21  Jonathan Coles   <[email protected]>
403    
404            * Thuban/UI/dock.py (DockFrame): Rename references to _OnClose
405            to OnClose so that Thuban closes correctly.
406    
407            * Thuban/UI/mainwindow.py (MainWindow.OnClose): Call
408            DockFrame.OnClose, not DockFrame._OnClose.
409    
410    2003-05-21  Jonathan Coles   <[email protected]>
411    
412            * Thuban/Model/classgen.py (ClassGenerator.GenQuantiles): Remove
413            references to 'inf' and use new Range __init__ to pass floats
414            directly rather than converting them to strings first.
415            Fixes RTBug #1876.
416    
417            * Thuban/Model/classification.py (ClassGroupRange.SetRange):
418            Use new Range ___init__ to pass floats.
419    
420            * Thuban/Model/layer.py (RasterLayer.__init__): Test if the
421            filename is a valid image file. Throw IOError otherwise.
422    
423            * Thuban/Model/range.py: Brought over new Range from SciParam that
424            is immutable and has an __init__ which can accept floats.
425    
426            * Thuban/UI/mainwindow.py (MainWindow.AddLayer): Move OpenShapefile
427            into try block. AddLayer doesn't throw any exceptions anymore.
428            (MainWindow.AddRasterLayer): Move constructor of RasterLayer into
429            try block.
430    
431            * Thuban/UI/projdialog.py (GeoPanel.__init__): Put Degrees as
432            the first item in choices. Fixes RTBug #1882.
433    
434            * Thuban/UI/renderer.py (MapRenderer.render_map): Check if scale
435            has gone to 0 which is a serious problem. abort.
436            (MapRenderer.draw_raster_layer): Catch IOError seperately and
437            print the error from GDAL.
438    
439            * Thuban/UI/tableview.py (TableGrid.__init__): Call
440            ToggleEventListeners to turn on listening.
441            (TableGrid.ToggleEventListeners): New. Turns event listening on
442            and off so as to prevent excessive messages.
443            (LayerTableFrame.OnQuery): Use TableGrid.ToggleEventListeners
444            to suppress excessive messages when selecting many rows.
445            Fixes RTBug #1880.
446    
447            * Thuban/UI/view.py: Added checks against if scale == 0. This
448            is a serious problem that can occur when an image without
449            geo data is loading and causes the map projection bounds to
450            go to infinity. Right now, the solution is to simply try
451            to recover.
452    
453            * extensions/thuban/cpl_mfile.cpp (MFILEClose): Make sure
454            to set the MFILEReceiver attributes even if the data is NULL.
455    
456            * extensions/thuban/gdalwarp.cpp: Improved the error handling
457            and passed GDAL messages back up to the Python layer. Also
458            tried to fix some memory leaks that were present in the original
459            utility but didn't matter because the program aborted.
460    
461            * test/test_range.py: Copied over tests from SciParam. Removed
462            tests against importing. Fixes RTBug #1867.
463    
464    2003-05-21  Bernhard Herzog  <[email protected]>
465    
466            * test/test_load.py: Remove unused imports and restructure the
467            test code
468            (LoadSessionTest): Split into one class for each test and turn
469            LoadSessionTest itself into the base class for all such session
470            tests.
471            (ClassificationTest): New base class for load tests that test
472            classifications
473            (TestSingleLayer, TestLayerVisibility, TestClassification)
474            (TestLabels, TestLayerProjection, TestRasterLayer): New classes
475            for the individual tests
476    
477            * test/support.py (FileLoadTestCase.filename): New base class for
478            file loading tests
479    
480    2003-05-21  Jan-Oliver Wagner <[email protected]>
481    
482            * Resources/Projections/defaults.proj: Renamed 'Universal Transverse
483            Mercator' to 'UTM Zone 32' as a more convenient example.
484            Added 'Gauss Krueger Zone 6'.
485    
486            * Data/iceland_sample_raster.thuban: political polygon now
487            filled transparent to have the raster image visible at once.
488    
489    2003-05-21  Frank Koormann  <[email protected]>
490    
491            * Thuban/UI/mainwindow.py (MainWindow): Renamed _OnClose() back to
492            OnClose() to keep in sync with extensions. Internally Thuban
493            still uses "underscored" names.
494    
495    2003-05-20  Jonathan Coles   <[email protected]>
496    
497            This puts back Raster layer support. These layers support projections
498            through the GDAL library. Currently, the CVS version is being used.
499            There are no Debian packages available although this may change soon.
500            A GDAL driver was extended to support writing to memory rather to
501            files.
502    
503            There is still some work that needs to be done, such as some error
504            handling when loading invalid images or when there is a problem
505            projecting the image. This putback simply checks in the majority
506            of the work.
507    
508            * setup.py: Add gdalwarp library extension.
509    
510            * Thuban/Model/layer.py (BaseLayer.HasClassification): New.
511            Defaults to False, but can be overridden by subclasses if they
512            support classification.
513            (RasterLayer): New. Defines a new layer that represents an
514            image.
515    
516            * Thuban/Model/load.py (SessionLoader.__init__): Add rasterlayer
517            tag handler.
518            (SessionLoader.start_layer): Encode the filename.
519            (SessionLoader.start_rasterlayer, SessionLoader.end_rasterlayer):
520            New. Supports reading a rasterlayer tag.
521    
522            * Thuban/Model/map.py (Map.BoundingBox): Fix typo in comment.
523    
524            * Thuban/Model/save.py (XMLWriter.encode): Don't assume that we
525            get a string in Latin1. If we get such as string convert it to
526            unicode first, otherwise leave if alone before encoding.
527            (SessionSaver.write_layer): Add support for writing both Layers
528            and RasterLayers.
529    
530            * Thuban/Model/transientdb.py (AutoTransientTable.SimpleQuery):
531            The right argument may not be a string, it could also be a Column.
532    
533            * Thuban/UI/application.py (ThubanApplication.CreateMainWindow):
534            Make initial window size 600x400. Fixes RTBug #1872.
535    
536            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange how
537            the dialog is constructed so that we can support layers that
538            do not have classifications.
539            (Classifier._OnTry): Only build a classification if the layer
540            supports one.
541    
542            * Thuban/UI/legend.py: Change all checks that a layer is an
543            instance of Layer into checks against BaseLayer.
544            (LegendTree.__FillTreeLayer): Only add children to a branch if
545            the layer supports classification.
546    
547            * Thuban/UI/mainwindow.py (MainWindow.NewSession,
548            MainWindow.OpenSession): Don't proceed with an action if the
549            user chooses Cancel when they are asked to save changes.
550            (MainWindow.AddRasterLayer): New. Open a dialog to allow the
551            user to select an image file. Create a new RasterLayer and add
552            it to the map.
553    
554            * Thuban/UI/renderer.py (MapRenderer.render_map): Add support
555            for rendering RasterLayer layers.
556            (MapRenderer.draw_raster_layer): Actually method that calls
557            the GDALWarp python wrapper and constructs an image from the
558            data returned.
559    
560            * Thuban/UI/tableview.py (LayerTableFrame.__init__): Change the
561            Choices symbols to match those used in the table query method.
562            Replace deprecated method calls on table with new method names.
563    
564            * Thuban/UI/view.py (MapCanvas.set_view_transform): Try to limit
565            how small the scale can get. This still needs more testing.
566    
567            * extensions/thuban/bmpdataset.cpp: New, but copied from GDAL.
568            Provides a driver to output in .bmp format.
569    
570            * extensions/thuban/cpl_mfile.cpp, extensions/thuban/cpl_mfile.h:
571            New. Provides IO routines which write to memory, rather than a file.
572    
573            * extensions/thuban/gdalwarp.cpp: New, but basically a direct copy
574            of the gdalwarp utility provided in GDAL. Added function calls
575            that can be accessed from python.
576    
577            * Data/iceland_sample_raster.thuban: New. Sample file that uses
578            a raster layer.
579

586            tests associated with the raster layer code.
587    
588            * test/test_transientdb.py
589            (TestTransientTable.test_auto_transient_table_query): Added a test
590            for using a Column object as the "right" parameter to a query.
591    
592    2003-05-19  Frank Koormann  <[email protected]>
593    
594            * Thuban/version.py (get_changelog_date):
595            Catch exceptions if ChangeLog does not exist.
596    
597            * Thuban/UI/view.py (MapCanvas.Export): Bugfix
598    
599    2003-05-19  Frank Koormann  <[email protected]>
600    
601            Extended version information for Thuban
602    
603            * Thuban/version.py: New, version information for Thuban: Last
604            modification date and last ChangeLog entry date.

610    
611            * Thuban/Model/save.py: Remove some unused imports including the
612            __future__ import for nested_scopes as Thuban relies on Python 2.2
613            now.
614            (XMLWriter.encode): Remove the special case for a None argument.
615            In the saver encode is always called with a string argument.
616    
617    2003-05-16  Bernhard Herzog  <[email protected]>
618    
619            * Thuban/UI/__init__.py: Remove the work-around for the locale bug
620            in wxPython (at least when usinvg wxGTK) prior to 2.4. The symptom
621            of the bug was that e.g. float("1.2") would fail. Thuban now
622            requires 2.4.x.
623            
624    2003-05-16  Frank Koormann   <[email protected]>

658            * Thuban/Model/table.py (Table): Remove this compatibility alias
659            for DBFTable.
660    
661            * test/test_table.py: Import DBFTable as Table because that alias
662            doesn't exist anymore.
663    
664            * Thuban/UI/classgen.py: Remove some unused imports
665

691            to table.UniqueValues() with calls that retrieve all the values
692            from the table. This will need to be replaced by a method on table
693            which can simply return the list (perhaps more efficiently).
694    
695    2003-05-12  Jonathan Coles   <[email protected]>
696    
697            The return value of ClassGenerator.CalculateQuantiles has changed.

710            in most cases.
711    
712    2003-05-12  Frank Koormann <[email protected]>
713            
714            * Thuban/Model/save.py (XMLWriter.encode()): Explicite call to unicode
715            and latin1. Fixes #1851 finally.

735            * Thuban/Model/classification.py: Explicit imports.
736            (ClassGroupRange): Use the Range class to store the underlying
737            range information. The interface remains the same, except for
738            GetRange(), and you can also supply a Range object as the min
739            parameter to SetRange or __init__.
740    
741            * Thuban/Model/load.py (XMLReader.encode): New. Encodes the given
742            string appropriately for use in Thuban. Fixes RTbug #1851.
743            (SessionLoader.end_projection): Handle the context of the
744            projection tag a bit better by looking at what objects are not
745            None. There was an assumption that a projection tag for a map
746            could occur before any layers.
747            (SessionLoader.start_clrange): Provide backward compatibility for
748            reading min/max values as well as the new range parameter.
749

760            (ClassGenDialog.__init__): Clean up the code and add support
761            for Quantiles.
762            (ClassGenDialog.OnOK): Add support for Quantiles.
763            (GenQuantilesPanel): New. Input panel for Quantiles.
764            (ClassGenerator, CustomRamp, MonochromaticRamp, GreyRamp, RedRamp,
765            GreenRamp, BlueRamp, HotToColdRamp): Move to Thuban/Model/classgen.py

784    
785            * Thuban/UI/tableview.py (TableGrid.OnRangeSelect): Fix some issues
786            with correctly selecting the rows and issuing the right events.
787            Be sure to call Skip() to allow the grid to do some of its own
788            handling which allows the rows to actually be selected.
789            (LayerTableGrid.select_shapes): Rename from select_shape. Supports
790            selecting multiple shapes.
791            (LayerTableFrame): Support for building Queries.
792            (LayerTableFrame.select_shapes): Allow multiple shapes to be selected.

807            the classifer table and elsewhere.
808    
809            * Thuban/UI/join.py: New. Initial Join dialog. No real functionality

931            Convert all table users to use the new table interface. This only
932            covers Thuban itself, not GREAT-ER or other applications built on
933            Thuban yet, so the compatibility interface stays in place for the
934            time being but it now issues DeprecationWarnings.
935    
936            Finally, the new Table interface has a new method, HasColumn.
937    
938            * Thuban/Model/table.py (OldTableInterfaceMixin): All methods

942            for the deprecation warnings
943    
944            * test/test_table.py: Ignore the deprecation warnings for the old

947    
948            * test/test_transientdb.py
949            (TestTransientTable.run_iceland_political_tests): Use the
950            constants for the types. Add a test for HasColumn

972            * Thuban/Model/transientdb.py (TransientTableBase.HasColumn)
973            (AutoTransientTable.HasColumn): Implement the new table interface
974            method
975            (AutoTransientTable.ReadRowAsDict, AutoTransientTable.ValueRange)
976            (AutoTransientTable.UniqueValues): Adapt to new table interface
977    
978            * Thuban/Model/layer.py (Layer.SetShapeStore, Layer.GetFieldType):

996            Addresses the "Selection Extent" wish of RTbug #1787.
997    
998            * Resources/Bitmaps/fulllayerextent.xpm,
999            Resources/Bitmaps/fullselextent.xpm: Bitmaps for layer and selection
1000            extent. These are just place holders for the real bitmaps.
1001    
1002            * Thuban/Model/layer.py (Shape): Since a Shape is immutable only
1003            calculate the bounding box once (the first time compute_bbox() is
1004            called).
1005            (Layer.ShapesBoundingBox): New. Given a list of shape ids, return
1006            the bounding box for the shapes in lat/long coordinates.
1007    
1008            * Thuban/UI/mainwindow.py: Added new "Full selection extent" menu
1009            option.

1018            true if there are any selected shapes.
1019    
1020            * Thuban/UI/view.py (MapCanvas): Added delegated method

1023            shapes on the canvas using the map projection (if any).
1024    
1025            * test/test_layer.py (TestLayer.test_arc_layer): Add some tests
1026            for Layer.ShapesBoundingBox().
1027    
1028    2003-05-06  Bernhard Herzog  <[email protected]>

1045    2003-05-05  Bernhard Herzog  <[email protected]>
1046    
1047            Convert the table implementations to a new table interface. All
1048            tables use a common mixin class to provide backwards compatibility
1049            until all table users have been updated.
1050    
1051            * Thuban/Model/table.py (OldTableInterfaceMixin): Mixin class to
1052            provide backwards compatibility for table classes implementing the
1053            new interface
1054            (DBFTable, MemoryTable): Implement the new table interface. Use
1055            OldTableInterfaceMixin as base for compatibility
1056            (DBFColumn, MemoryColumn): New. Column description for DBFTable
1057            and MemoryTable resp.
1058    
1059            * test/test_dbf_table.py: New. Test cases for the DBFTable with
1060            the new table interface.
1061    
1062            * test/test_memory_table.py: New. Test cases for the MemoryTable
1063            with the new table interface.
1064    
1065            * test/test_table.py: Document the all tests in this file as only
1066            for backwards compatibility. The equivalent tests for the new
1067            interface are in test_memory_table.py and test_dbf_table.py
1068            (MemoryTableTest.test_read): field_info should be returning tuples
1069            with four items
1070            (MemoryTableTest.test_write): Make doc-string a more precise.
1071    
1072            * Thuban/Model/transientdb.py (TransientTableBase): Convert to new
1073            table interface. Derive from from OldTableInterfaceMixin for
1074            compatibility.
1075            (TransientTableBase.create): New intance variable column_map to
1076            map from names and indices to column objects
1077            (TransientTable.create): Use the new table interface of the input
1078            table
1079            (AutoTransientTable): Convert to new table interface. Derive from
1080            from OldTableInterfaceMixin for compatibility.
1081            (AutoTransientTable.write_record): Removed. It's not implemented
1082            yet and we still have to decide how to handle writing with the new
1083            table and data framework.
1084    
1085            * test/test_transientdb.py
1086            (TestTransientTable.run_iceland_political_tests)
1087            (TestTransientTable.test_transient_joined_table): Use the new
1088            table interface
1089    
1090    2003-05-05  Jonathan Coles   <[email protected]>
1091    
1092            This is namely a collection of UI updates to improve user interactivity.
1093            Tabbing between controls now exists and you can use ESC to close dialog
1094            boxes; ENTER will active the default button.
1095    
1096            * Thuban/UI/classgen.py (ClassGenDialog.__init__): Rearrange the
1097            order that the controls are created so that tabbing works correctly.
1098            (ClassGenDialog.OnOK): Renamed from _OnGenerate() so that the
1099            wxDialog can handle the default button correctly.
1100            (ClassGenDialog.OnCancel): Renamed from _OnCloseBtn() for the
1101            same reasons as for OnOK.
1102            (GenUniformPanel._OnRetrieve): Call wxBeginBusyCursor/wxEndBusyCursor
1103            when we ask the table for the maximum/minimum values of a field
1104            which could take a very long time.
1105    
1106            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange the
1107            order that the controls are created so that tabbing works correctly.
1108            (SelectPropertiesDialog.__init__): Rearrange the order that the
1109            controls are created so that tabbing works correctly.
1110    
1111            * Thuban/UI/dialogs.py: Copied NonModalDialog box and changed it
1112            to derive from a wxDialog but behave like the original implementation
1113            which was derived from a wxFrame. wxDialog provides useful key
1114            handling functionality like ESC calling OnCancel and ENTER calling
1115            OnOK which is lost with wxFrame.
1116    
1117            * Thuban/UI/mainwindow.py: Add "..." to menu items that will open
1118            new dialogs.
1119    
1120            * Thuban/UI/projdialog.py (ProjFrame.__init__): Rearrange the
1121            order that the controls are created so that tabbing works correctly.
1122            (ProjFrame.OnApply): Renamed from _OnTry() to use wxDialog behaviour.
1123            (ProjFrame.OnOK): Renamed from _OnOK() to use wxDialog behaviour.
1124            (ProjFrame.OnCancel): Renamed from _OnClose() to use wxDialog behaviour.
1125            (ProjPanel.__init__): Add "Airy" to the list of ellipsoids so we
1126            can provide the "UK National Grid" as a default projection.
1127            (UTMPanel.__init__): Rearrange the order that the controls are
1128            created so that tabbing works correctly.
1129    
1130    2003-05-05  Bernhard Herzog  <[email protected]>
1131    
1132            * extensions/thuban/wxproj.cpp: Fix some of the comments.
1133            (project_point): If a map projection but no layer projection is
1134            given, convert degrees to radians before applying the map
1135            projection.
1136    
1137            * Thuban/UI/tableview.py (TableGrid.disallow_messages)
1138            (TableGrid.allow_messages): New methods to make it possible to
1139            inhibit message sending.
1140            (TableGrid.issue): Only send the message if not inhibited.
1141            (LayerTableGrid.select_shape): Use the new methods to make sure
1142            that no ROW_SELECTED message is sent while we're updating the
1143            selected rows to match the selected shapes.
1144    
1145    2003-05-02  Jan-Oliver Wagner <[email protected]>
1146    
1147            Implementation of MemoryTable.
1148    
1149            * Thuban/Model/table.py (MemoryTable): New. Quite simple table
1150            implementation that operates on a list of tuples. All of the data
1151            are kept in the memory.
1152    
1153            * test/test_table.py (MemoryTableTest): New.
1154    
1155            * test/test_transientdb.py (SimpleTable): Removed.
1156            (TestTransientTable.test_transient_joined_table,
1157            (TestTransientTable.test_transient_table_read_twice): Replaced
1158            SimpleTable by MemoryTable.
1159    
1160    2003-04-30  Jonathan Coles   <[email protected]>
1161    
1162            * Data/iceland_sample.thuban: Now contains correct projections
1163            for each of the layers.
1164    
1165            * Resources/Projections/defaults.proj: Geographic projection
1166            contains unit conversion parameter.
1167    
1168    2003-04-30  Jonathan Coles   <[email protected]>
1169    
1170            The most important part of this putback is the projection changes.
1171            It should now be possible to specify the projection that a layer
1172            is in and then specify a different projection for the map. The
1173            projection dialog has an extra parameter for a geographic projection
1174            which lets the user select if the input is in degrees or radians.
1175    
1176            * Thuban/Model/layer.py (Layer.ShapesInRegion): Fix docstring
1177            to say that the parameter is a tuple of unprojected
1178            points (which is what the callers to this method were assuming).
1179            Also, since the points are unprojected we need to projected them.
1180    
1181            * Thuban/UI/legend.py (LegendTree.MoveCurrentItemUp,
1182            LegendTree.MoveCurrentItemDown): If the layer or any of the layer's
1183            groups are selected, move the layer up/down. Fixes RTbug #1833.
1184    
1185            * Thuban/UI/mainwindow.py: Move menu item map_rename up.
1186    
1187            * Thuban/UI/projdialog.py (ProjFrame._OnSave): Add missing
1188            parameter in call to SetClientData.
1189            (GeoPanel): Add support for selecting the units that the
1190            source data is in (Radians or Degrees).
1191    
1192            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Optimize
1193            the rendering loop by reducing the number of if's, removing the
1194            unnecessary try/except block, and checking if the old group
1195            is the same as the new one (which happens a lot if there is
1196            no classification, or lots of shapes are in the same group).
1197    
1198            * Thuban/UI/view.py (MapCanvas.OnPaint): Add a try/except block
1199            around the redraw routine to try to catch problems that the user
1200            may create by selecting invalid projections for the data set and
1201            map. Clears the display if there are any problems and prints the
1202            error.
1203            (MapCanvas.do_redraw): Use DC.Clear() instead of drawing a filled
1204            rectangle.
1205    
1206            * extensions/thuban/wxproj.cpp (project_point): First invert the
1207            supplied point (which should be in projected coordinates) using
1208            the layer's projection and then project the point using the
1209            map's projection.
1210            (project_points): Use project_point() to project each point.

1213    
1214            * Thuban/Model/layer.py (Layer.SetShapeStore): Fixed a bug:
1215            don't set the Classification to None if the classfication field
1216            is None (ie only a DEFAULT).
