[Qgis-developer] Ending edit shapefile in Python plugin

[Benoit de Cabissole]

To whom may be interested,

A workaround to the problem described below is to call:
   self.theLayer.setSelectedFeatures([])
after
   self.iface.mapCanvas().refresh()

This will reset the edit toolbar to the correct state (no edit).

I do not think it is the correct way of doing things but it works!

Cheers,
Benoit
