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 |
|
|
| 47 |
|
* Thuban/UI/view.py (MapCanvas.FitMapToWindow): This may be called |
| 48 |
|
during startup before a map has been created. Check if map is None |
| 49 |
|
before using it and do nothing if it is. |
