I need to iterate through all the categories in a layer's renderer. I've
figured out how to get the value and the symbol info:
categories = layer.rendererV2().categories()
for cat in categories:
print cat.value()
print cat.symbol().color().name()
How do I find out which of the layer's fields is driving the categorization? In
other words, how do I get the field which is compared against cat.value() in
order to determine whether the category applies to a given feature?
This is for the qgis2leaf plugin. I need to read out all the categories and
rewrite them in javascript which Leaflet can understand.
Thanks
Tom
