[Qgis-developer] Wierd issue with Python and triggerRepaint()

[Martin Dobias]

Hi Gary

I cannot replicate your problem (tried 2.6 and master). I have attached a
very simple test plugin that first creates an layer and then adds a feature
on a click of a button. With the triggerRepaint() call the canvas is
refreshed correctly (when caching is enabled on or not). Let me know if
that code works for you - maybe your problem is somewhere else or it is
more complex.

Cheers
Martin
