I have a plugin that makes modifications to a memory layer, then
calls triggerRepaint() to refresh. Unfortunately, it doesn't
refresh the layer. If I open the Python console before making the
mods, it works from the console:
lyr = iface.activeLayer()
lyr.triggerRepaint()
If I turn off caching in Settings, I don't have a problem with my
plugin.
Which version of QGIS is that?
2.6
In QGIS < 2.4 you had to explicitly call lyr.clearCacheImage() if the
caching was turned on - otherwise the renderer would still use the
cached image stored in the layer's instance. Since 2.4 that is not
necessary anymore and triggerRepaint() should also clear renderer's
cached layer image.
Right, and that worked fine for me at 2.4.
Thanks,
