<pre wrap="">The following code works for a layer which has the 2.5d renderer selected:
feats = layer.getFeatures()
for feat in feats:
symbol = layer.rendererV2().symbolForFeature(feat)
This still works if I change the layer to a single symbol renderer. However,
if I change it to a categorized symbol renderer, and classify on one field
(random colours, nothing else in the style changed from the 2.5d), the last
line above causes a mindump.
Can anyone help?
