When Thuban loaded the map was redrawn twice because the |
| 4 |
|
legend was being opened after the mainwindow was created |
| 5 |
|
and not during its creation. This meant the map was drawn |
| 6 |
|
initially and then had to be redrawn when the legend |
| 7 |
|
caused the display to change. Now the legend is opened |
| 8 |
|
in the mainwindow constructor which resolves this issue. |
| 9 |
|
|
| 10 |
|
Also, although we were checking for the existence of |
| 11 |
|
gdal and gdalwarp modules, the gdalwarp extension was |
| 12 |
|
still being compiled (which may fail if the system doesn't |
| 13 |
|
have gdal installed). the build_ext command to setup.py |
| 14 |
|
now accepts the flags --with-gdal and --without-gdal. |
| 15 |
|
If --without-gdal is specified setup.py will try to |
| 16 |
|
use the gdal parameters specified by gdal-config. Under |
| 17 |
|
windows, those parameters have to be set in setup.py |
| 18 |
|
as with proj4 an wxWindows. |
| 19 |
|
|
| 20 |
|
* setup.py: Use a list instead of seperate variables for |
| 21 |
|
extension parameters so we can create a generic function |
| 22 |
|
that runs an appropriate *-config script. |
| 23 |
|
(run_cs_script): Renamed from run_wx_script and modified |
| 24 |
|
to accept a second argument which is a list of lists to |
| 25 |
|
be filled in by the values returned from running the command. |
| 26 |
|
(thuban_build_ext): New. Extends the build_ext command and |
| 27 |
|
provides the options --with-gdal/--without-gdal which then |
| 28 |
|
optionally includes the gdalwarp extension. |
| 29 |
|
|
| 30 |
|
* Thuban/Model/resource.py: First check if we can import |
| 31 |
|
the gdalwarp Thuban extension before checking for gdal. |
| 32 |
|
Also added some comments. |
| 33 |
|
|
| 34 |
|
* Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Check if |
| 35 |
|
the map is None which may be the case if none has been loaded |
| 36 |
|
yet. |
| 37 |
|
|
| 38 |
|
* Thuban/UI/main.py (main): Remove call to ShowLegend. |
| 39 |
|
|
| 40 |
|
* Thuban/UI/mainwindow.py (MainWindow.__init__): Call ShowLegend(). |
| 41 |
|
|
| 42 |
|
* Thuban/UI/renderer.py: Check for gdal support before importing |
| 43 |
|
gdalwarp. |
| 44 |
|
(MapRenderer.render_map): Only try to optimize if we have gdal |
| 45 |
|
support otherwise nothing will get drawn. |
| 46 |
|
(MapCanvas.FitMapToWindow): This may be called during startup |
| 47 |
|
before a map has been created. Check if map is None before |
| 48 |
|
using it and do nothing if it is. |
| 49 |

|
Fix the problem with raster layers under Windows that caused |
| 53 |
|
Thuban to crash. The view should respond to layer projection |
| 54 |
|
changed events to update the display. Changes to a projection |
| 55 |
|
should not cause the map to be set to full extent. |
| 56 |
|
|
| 57 |
|
* Thuban/UI/view.py (MapCanvas.__init__): New instance variable |
| 58 |
|
current_map_proj to remember the current map projection so that |
| 59 |
|
when the projection changes we know what the previous projection |
| 60 |
|
was. |
| 61 |
|
(MapCanvas.SetMap): Unsubscribe and subscribe to |
| 62 |
|
LAYER_PROJECTION_CHANGED events. |
| 63 |
|
(MapCanvas.projection_changed): Split into two methods that respond |
| 64 |
|
to map and layer projection changes. |
| 65 |
|
(MapCanvas.map_projection_changed): New. Takes the current view and |
| 66 |
|
projects it using the new projection. This does not cause the |
| 67 |
|
map to be redrawn at full extent. |
| 68 |
|
(MapCanvas.layer_projection_changed): New. Cause a redraw which |
| 69 |
|
will draw each layer in its new projection. |
| 70 |
|
|
| 71 |
|
* extensions/thuban/bmpdataset.cpp (BMPDataset::Open): Call |
| 72 |
|
VSIFClose() not VSIFCloseL() to close the file. Fixes a crash |
| 73 |
|
under Windows. |
| 74 |
|
|
| 75 |
|
* extensions/thuban/gdalwarp.cpp (MFILENAME): Padding should be |
| 76 |
|
to twice sizeof(void*) because there are two digits for each |
| 77 |
|
hex byte. |

Update to the layer interface: Direct access to the table, |
| 82 |
|
shapetable, shapefile and filename attributes is now actively |
| 83 |
|
deprecated by issuing deprecation warnings for all places where |
| 84 |
|
this happens. |
| 85 |
|
|
| 86 |
|
* Thuban/Model/layer.py (Layer.__getattr__): New. Implement access |
| 87 |
|
to the instance variables table, shapetable, shapefile and |
| 88 |
|
filename via __getattr__ so that we can issue a deprecation |
| 89 |
|
warning. |
| 90 |
|
(Layer.SetShapeStore): Don't set the deprecated instance variables |
| 91 |
|
any more |
| 92 |

|
instance variables |

| 100 |
|
(GenUniformPanel._OnRetrieve, GenUniquePanel._OnRetrieve) |
| 101 |

(GenQuantilesPanel.GetList, GenQuantilesPanel.OnRetrieve): Don't |
| 102 |
|
use deprecated layer instance variables |
| 103 |

| 105 |
|
deprecated layer instance variables |
| 106 |
|
|
| 107 |
|
* Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape) |
| 108 |
|
(IdentifyGridCtrl.selected_shape): Don't set the deprecated layer |
| 109 |
|
instance variables |

| 112 |
|

| 115 |
|

| 121 |
|
(MapRenderer.polygon_render_param): Don't use deprecated layer instance |
| 122 |
|
variables |
| 123 |
|
|
| 124 |
|

| 125 |
|
errors so that they're cought by the tests |
| 126 |
|
|
| 127 |
|

Fix a problem under Windows whereby if the user double-clicks on a |
| 133 |
|
layer in the legend that tree item will expand or collapse as well |
| 134 |
|
as open the layer properties dialog. The state of the tree item |
| 135 |
|
should not be affected. |
| 136 |
|
|
| 137 |
|
* Thuban/UI/legend.py (LegendTree.__init__): Add instance variable |
| 138 |
|
preventExpandCollapse and subscribe to expanding and collapsing |
| 139 |
|
events. |
| 140 |
|
(LegendTree.OnItemExpandCollapse): New. Responds to expanding and |
| 141 |
|
collapsing events and will veto the event if it has been triggered |
| 142 |
|
by the user double clicking on a layer. |
| 143 |
|
(LegendTree._OnItemActivated): Set preventExpandCollapse to indicate |
| 144 |
|
that an expanding/collapsing event should be vetoed. |
