- you can now define a Python class as a synthetic children producer for a type
the class must adhere to this "interface":
def __init__(self, valobj, dict):
def get_child_at_index(self, index):
def get_child_index(self, name):
then using type synth add -l className typeName
(e.g. type synth add -l fooSynthProvider foo)
(This is still WIP with lots to be added)
A small test case is available also as reference
