Is it possible to programmatically detect checking/unchecking changes of a rule in a rule-based rendering ? I found no indication of existing signals ..

I got lost reading QgsVectorLayerRenderer Class Reference ...

Seeking preferably a solution for QGIS 3.x

  • well ... i understand your comment but i'm stuck at the very beginning ... i've read the documentation of the class and found no usable ... i've maybe skipped some information but in fact i haven't found any signal related with that clas ...so i'm a bit lost and searching for a starting point ... – snaileater Mar 21 at 8:37
