[Qgis-developer] Python QgsVectorLayer question

[Chris Crook]

Hi

I'm working on a plugin which creates vector layers

   layer = QgsVectorLayer(...)

These are based upon information in other layers, so I want to set the same crs as the source layer.  This seems easy enough

   layer.setCrs(sourceLayer.crs(),False)

However the problem I have is that if the Qgis settings for new layers is to prompt for the CRS (Settings|Options|CRS|Prompt for CRS), then the CRS selection dialog appears as soon as the new layer is created.  Obviously I don't want this, since I'm going to reset the CRS regardless of what the user chooses.

Is there a good way to avoid this.  At the moment I'm using a rather kludgy approach,  

        settings = QSettings()
        prjSetting = settings.value("/Projections/defaultBehaviour").toString()
        try:
           settings.setValue("/Projections/defaultBehaviour","")
          ... do my stuff ...
        finally:
           if prjSetting:
               settings.setValue("/Projections/defaultBehaviour",prjSetting)

But this doesn't seem ideal..

Cheers
Chris
