Implementation of MemoryTable. |
| 4 |
|
|
| 5 |
|
* Thuban/Model/table.py (MemoryTable): New. Quite simple table |
| 6 |
|
implementation that operates on a list of tuples. All of the data |
| 7 |
|
are kept in the memory. |
| 8 |
|
|
| 9 |
|
* test/test_table.py (MemoryTableTest): New. |
| 10 |
|
|
| 11 |
|
* test/test_transientdb.py (SimpleTable): Removed. |
| 12 |
|
(TestTransientTable.test_transient_joined_table, |
| 13 |
|
(TestTransientTable.test_transient_table_read_twice): Replaced |
| 14 |
|
SimpleTable by MemoryTable. |

|
|
| 18 |
|
* Data/iceland_sample.thuban: Now contains correct projections |
| 19 |
|
for each of the layers. |
| 20 |
|
|
| 21 |
|
* Resources/Projections/defaults.proj: Geographic projection |
| 22 |
|
contains unit conversion parameter. |
| 23 |

|
The most important part of this putback is the projection changes. |
| 27 |
|
It should now be possible to specify the projection that a layer |
| 28 |
|
is in and then specify a different projection for the map. The |
| 29 |
|
projection dialog has an extra parameter for a geographic projection |
| 30 |
|
which lets the user select if the input is in degrees or radians. |
| 31 |
|
|
| 32 |
|
* Thuban/Model/layer.py (Layer.ShapesInRegion): Fix docstring |
| 33 |
|
to say that the parameter is a tuple of unprojected |
| 34 |
|
points (which is what the callers to this method were assuming). |
| 35 |
|
Also, since the points are unprojected we need to projected them. |
| 36 |
|
|
| 37 |
|
* Thuban/UI/legend.py (LegendTree.MoveCurrentItemUp, |
| 38 |
|
LegendTree.MoveCurrentItemDown): If the layer or any of the layer's |
| 39 |
|
groups are selected, move the layer up/down. Fixes RTbug #1833. |
| 40 |
|
|
| 41 |
|
* Thuban/UI/mainwindow.py: Move menu item map_rename up. |
| 42 |
|
|
| 43 |
|
* Thuban/UI/projdialog.py (ProjFrame._OnSave): Add missing |
| 44 |
|
parameter in call to SetClientData. |
| 45 |
|
(GeoPanel): Add support for selecting the units that the |
| 46 |
|
source data is in (Radians or Degrees). |
| 47 |
|
|
| 48 |
|
* Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Optimize |
| 49 |
|
the rendering loop by reducing the number of if's, removing the |
| 50 |
|
unnecessary try/except block, and checking if the old group |
| 51 |
|
is the same as the new one (which happens a lot if there is |
| 52 |
|
no classification, or lots of shapes are in the same group). |
| 53 |
|
|
| 54 |
|
* Thuban/UI/view.py (MapCanvas.OnPaint): Add a try/except block |
| 55 |
|
around the redraw routine to try to catch problems that the user |
| 56 |
|
may create by selecting invalid projections for the data set and |
| 57 |
|
map. Clears the display if there are any problems and prints the |
| 58 |
|
error. |
| 59 |
|
(MapCanvas.do_redraw): Use DC.Clear() instead of drawing a filled |
| 60 |
|
rectangle. |
| 61 |
|
|
| 62 |
|
* extensions/thuban/wxproj.cpp (project_point): First invert the |
| 63 |
|
supplied point (which should be in projected coordinates) using |
| 64 |
|
the layer's projection and then project the point using the |
| 65 |
|
map's projection. |
| 66 |
|
(project_points): Use project_point() to project each point. |
| 67 |
|
|

|
2003-04-30 Jan-Oliver Wagner <[email protected]> |
| 69 |
|
|
| 70 |
|
* Thuban/Model/layer.py (Layer.SetShapeStore): Fixed a bug: |
| 71 |
|
don't set the Classification to None if the classfication field |
| 72 |
|
is None (ie only a DEFAULT). |
| 73 |
|
|

|

| 75 |
|
|
| 76 |
|
* Thuban/UI/view.py: Fix some typos. |
| 77 |
|
|
| 78 |
|
* Thuban/UI/mainwindow.py (MainWindow.identify_view_on_demand): Do |
| 79 |
|
not pop up the dialog if the selection becomes empty (this could |
| 80 |
|
happen if e.g. a new selection is opened while the identify tool |
| 81 |
|
is active and dialog had been closed) |
| 82 |
|
|
| 83 |
|
2003-04-30 Bernhard Herzog <[email protected]> |
| 84 |
|
|
| 85 |
|
* Thuban/Model/transientdb.py (TransientTableBase.__init__): New |
| 86 |
|
instance variable read_record_last_result |
| 87 |
|
(TransientTableBase.read_record): Make sure reading the same |
| 88 |
|
record twice works. The implementation uses the new instance |
| 89 |
|
variable read_record_last_result |
| 90 |
|
|
| 91 |
|
* test/test_transientdb.py |
| 92 |
|
(TestTransientTable.test_transient_table_read_twice): New test |
| 93 |
|
case for the above bug-fix. |
| 94 |
|
|
| 95 |
|
2003-04-29 Jonathan Coles <[email protected]> |
| 96 |
|
|
| 97 |
|
* Thuban/common.py: Removed. No longer needed Str2Num. RTbug #1832. |
| 98 |
|
|
| 99 |
|
* Thuban/UI/classgen.py: Remove all uses of Str2Num. |
| 100 |
|
|
| 101 |
|
* Thuban/UI/classifier.py: Remove all uses of Str2Num. |
| 102 |
|
(ClassTable.SetValueAsCustom): Rename keyword argument in |
| 103 |
|
ClassGroup* constructors to match argument name. |
| 104 |
|
|
| 105 |
|
2003-04-29 Bernhard Herzog <[email protected]> |
| 106 |
|
|
| 107 |
|
* Thuban/Model/session.py (Session.Destroy): Explicitly close the |
| 108 |
|
transient DB if it exists to make sure it doesn't leave a journal |
| 109 |
|
file in the temp directory. |
| 110 |
|
|
| 111 |
|
* Thuban/Model/transientdb.py (TransientDatabase.close): Set |
| 112 |
|
self.conn to None after closing the connection to make sure it's |
| 113 |
|
not closed twice |
| 114 |
|
|
| 115 |
|

|
|
| 117 |
|
Add a visible parameter in the layer XML tag. The default value is |
| 118 |
|
"true". If anything other than "false" is specified we also assume |
| 119 |
|
"true". Addresses RTbug #1025. |
| 120 |
|
|
| 121 |
|
* Doc/thuban.dtd: Add visible parameter to a layer. |
| 122 |
|
|
| 123 |
|
* Thuban/Model/layer.py (BaseLayer.__init__): Change default value |
| 124 |
|
of visible from 1 to True. |
| 125 |
|
(Layer.__init__): Change default value of visible from 1 to True. |
| 126 |
|
|
| 127 |
|
* Thuban/Model/load.py (SessionLoader.start_layer): Read visible |
| 128 |
|
parameter. |
| 129 |
|
|
| 130 |
|
* Thuban/Model/save.py (SessionSaver.write_layer): Save visible |
| 131 |
|
parameter. |
| 132 |
|
|
| 133 |
|
* test/test_load.py: Add new test data contents_test_visible. |
| 134 |
|
(LoadSessionTest.setUp): save test data. |
| 135 |
|
(LoadSessionTest.testLayerVisibility): Test if the visible flag |
| 136 |
|
is loaded correctly. |
| 137 |
|
|
| 138 |
|
* test/test_save.py (SaveSessionTest.testSingleLayer): Add test |
| 139 |
|
for saving an invisible layer. |

| 142 |
|
|
| 143 |
|
* Thuban/UI/mainwindow.py (MainWindow.SetMap): Look up the |
| 144 |
|
legend dialog box and tell it to change its map to the one |
| 145 |
|
supplied to SetMap(). Fixes RTbug #1770. |
| 146 |

|
Next step of table implementation. Introduce a transient database |
| 150 |
|
using SQLite that some of the data is copied to on demand. This |
| 151 |
|
allows us to do joins and other operations that require an index |
| 152 |
|
for good performance with reasonable efficiency. Thuban now needs |
| 153 |
|
SQLite 2.8.0 and pysqlite 0.4.1. Older versions may work but I |
| 154 |
|
haven't tested that. |
| 155 |
|
|
| 156 |
|
* Thuban/Model/transientdb.py: New. Transient database |
| 157 |
|
implementation. |
| 158 |
|
|
| 159 |
|
* test/test_transientdb.py: New. Tests for the transient DB |
| 160 |
|
classes. |
| 161 |
|
|
| 162 |
|
* Thuban/Model/session.py (AutoRemoveFile, AutoRemoveDir): New |
| 163 |
|
classes to help automatically remove temporary files and |
| 164 |
|
directories. |
| 165 |
|
(Session.__init__): New instance variables temp_dir for the |
| 166 |
|
temporary directory and transient_db for the SQLite database |
| 167 |
|
(Session.temp_directory): New. Create a temporary directory if not |
| 168 |
|
yet done and return its name. Use AutoRemoveDir to have it |
| 169 |
|
automatically deleted |
| 170 |
|
(Session.TransientDB): Instantiate the transient database if not |
| 171 |
|
done yet and return it. |
| 172 |
|
|
| 173 |
|
* Thuban/Model/data.py (ShapefileStore.__init__): Use an |
| 174 |
|
AutoTransientTable so that data is copied to the transient DB on |
| 175 |
|
demand. |
| 176 |
|
(SimpleStore): New class that simply combines a table and a |
| 177 |
|
shapefile |
| 178 |
|
|
| 179 |
|
* Thuban/Model/table.py (Table, DBFTable): Rename Table into |
| 180 |
|
DBFTable and update its doc-string to reflect the fact that this |
| 181 |
|
is only the table interface to a DBF file. Table is now an alias |
| 182 |
|
for DBFTable for temporary backwards compatibility. |
| 183 |
|
|
| 184 |
|
* Thuban/UI/application.py (ThubanApplication.OnExit): Make sure |
| 185 |
|
the last reference to the session goes away so that the temporary |
| 186 |
|
files are removed properly. |
| 187 |
|
|
| 188 |
|
* test/test_load.py (LoadSessionTest.tearDown): Remove the |
| 189 |
|
reference to the session to make sure the temporary files are |
| 190 |
|
removed. |
| 191 |
|
|
| 192 |
|

| 193 |
|
|
| 194 |
|
* Thuban/Model/load.py (XMLReader.__init__, XMLReader.read): Turn |
| 195 |
|
the __parser instance variable into a normal local variable in |
| 196 |
|
read. It's only used there and read will never be called more than |
| 197 |
|
once. Plus it introduces a reference cycle that keeps can keep the |
| 198 |
|
session object alive for a long time. |
| 199 |

|
| 202 |
|
* Thuban/Model/proj.py (Projection): Removed Set*() methods to make |
| 203 |
|
Projection an immutable item. Fixes RTbug #1825. |
| 204 |
|
(Projection.__init__): Initialize instance variables here. |
| 205 |
|
(ProjFile.Replace): New. Replace the given projection object with |
| 206 |
|
the new projection object. This solves the problem of needing the |
| 207 |
|
mutator Projection.SetProjection() in the ProjFrame class and |
| 208 |
|
allows a projection to change parameters without changing its |
| 209 |
|
location in the file. |
| 210 |
|
|
| 211 |
|
* Thuban/UI/mainwindow.py (MainWindow.SaveSessionAs): Dialog should |
| 212 |
|
be of type wxSAVE and should verify overwriting a file. |
| 213 |
|
|
| 214 |
|
* Thuban/UI/projdialog.py (ProjFrame._OnSave): Use the new |
| 215 |
|
ProjFile.Replace() method instead of the mutator |
| 216 |
|
Projection.SetProjection(). Also requires that we reassign the |
| 217 |
|
client data to the new projection. |
| 218 |
|
|
| 219 |
|
* test/test_proj.py (TestProjection.test): Test GetName() and |
| 220 |
|
GetAllParameters() |
| 221 |
|
(TestProjFile.test): Remove tests for Set*() methods. Add tests |
| 222 |
|
for Replace(). |

| 235 |
|
to "Unknown" if name is None. |
| 236 |
|
(Projection.SetAllParameters): New. Set the projection's |
| 237 |
|
parameter list to the one supplied. |
| 238 |
|
(Projection.SetProjection): New. Set the projection's |
| 239 |
|
properties to those of the supplied Projection. |
| 240 |
|
|
| 241 |
|
* Thuban/UI/mainwindow.py (MainWindow.MapProjection): Set |
| 242 |
|
the dialog title to include the map's title. |
| 243 |

(MainWindow.LayerProjection): Set the dialog title to include |
| 244 |
|
the layer's title. |
| 245 |
|
|
| 246 |
|
* Thuban/UI/projdialog.py (ProjFrame.__ShowError): Consolidate |
| 247 |
|
error dialogs into a single method call. |
| 248 |
|
(ProjFrame.__VerifyButtons): Add more states to check. |
| 249 |
|
(ProjFrame.__GetProjection): Return the current state of an |
| 250 |
|
edited projection or None. |
| 251 |
|
(ProjFrame.__FillAvailList): Remove checks for states that |
| 252 |
|
shouldn't exist. |
| 253 |
|
(ProjFrame._OnNew): Clear all selected items and supply |
| 254 |
|
a projection panel if necessary. |
| 255 |
|
|
| 256 |
|
* test/test_proj.py (TestProjFile.test): Add tests for |
| 257 |
|
ProjFile.SetAllParameters, ProjFile.SetProjection, |
| 258 |
|
ProjFile.SetName. |

2003-04-25 Jonathan Coles <[email protected]> |
| 261 |
|
|
| 262 |
|
* Thuban/UI/projdialog.py (ProjFrame.__FillAvailList): Now |
| 263 |
|
takes an optional argument to select the current projection. |
| 264 |
|
This does not guarantee that the item is visible due to |
| 265 |
|
limited wxWindows functionality. Fixes RTBug #1821. |
