Quote - I know there is the "hack" function in Python to get the functions of the Poser module... But is there a way to know what are those WidgetProcID and BehaviorProcID ?

Take a look through the XML files in Runtimeui

I suspect that these are custom control handlers in Poser's code and not avaliable to Python.

Now if EF would properly expose the internal wxWindows implementation to Python, then we might get somewhere.
