[Qgis-developer] new GRASS 6.4 modules
Hi all. In the occasion of the release of GRASS 6.4, I think it would be good to revise the current QGIS-GRASS modules. Specifically: - there are modules that IMHO are of no use, and potentially confusing (e.g. several of those who manage projections, etc.) - there are new and useful modules to add to the toolbox - not all modules have been thoroughly tested. I encourage therefore GRASS users to help us defining both a wishlist for modules to be included ad a deprecated list, and to let us know if there are non-functional modules, so they can be fixed. Thanks. -- Paolo Cavallini: http://www.faunalia.it/pc ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
[Qgis-developer] viewing feature form
Dear QGIS devs, since this is my first post on this list I want to thank all of you for your efforts in providing and improving this wonderful piece of software. My question is as follows: How can I open the feature form for a feature through Python i.e. how can I make the same happen as if the user used the identifyTool and clicked on actions - View feature form? regards Benno -- Dipl.-Geogr.

[Qgis-developer] Not Rendering the Shapefile in Canvas - Blank
Hi, Is there any reason why the shapefile is not rendering in this code (below)? I tried several shapefiles and yet I am getting a white canvas or blank canvas without a render. I was able to open the shapefile and the form with mapcanvas are showing. Yet no render of the polygons - totally blank. self.canvas.setCanvasColor(Qt.white) a White Canvas without render - BLANK Thanks.

Hi Cédric I inserted self.canvas.refresh() as showed below but still a blank canvas. # Set up the map canvas layer set cl = QgsMapCanvasLayer(layer) layers = [cl] self.canvas.setLayerSet(layers) self.canvas.refresh() ~ Thanks.

[Qgis-developer] PyQGIS - Selecting Spatialite Datasource at runtime
Hi,
Given, this example from PyQGIS documentation.
uri = QgsDataSourceURI()
uri.setDatabase('/home/martin/test-2.3.sqlite')
uri.setDataSource('','Towns', 'Geometry')
layer = QgsVectorLayer(uri.uri(), 'Towns', 'spatialite')
~
How do you do a runtime for the above. I want to select the table /
layer to load. How you figure out the uri.setDataSource('',' ',
'Geometry') and QgsVectorLayer(uri.uri(), ' ', 'Spatialite')?
file = QFileDialog.getOpenFileName(self,Open Spatialite, .,
Spatialite (*.sqlite))
fileInfo = QFileInfo(file)
uri = QgsDataSourceURI()
uri.setDatabase(file)
uri.setDataSource('',' ', 'Geometry')
# Add the layer
layer = QgsVectorLayer(uri.uri(), ' ', 'Spatialite')
~

Hi Noli,
you could use this [1] (sorry, it's in Spanish). It uses the Sqlite3 Python
module [2].
