Error in Shiboken-generated wrapper for wigglywidget example: incomplete types, missing arguments and undefined identifiers.

There are some errors in the generated files from shiboken6. Errors include missing argument in function call and usage of undefined types. Shiboken6 is not working correctly here. This doesn't occur when we generate bindings for a non-qt project. This occurs only when we generate bindings for a qt based project. When I tried to generate bindings for some custom widgets I made, I encountered the same issue. Because of this, I can't generate bindings and finish building.
