I don't find any use of %ConvertToSubClassCode in PyKDE.

KXMLGUIFactory.container() looks like it can return instances of KMainWindow, 
KMenuBar, KPopupMenu, KToolBar, or KStatusBar. It gets them from a DOM-like 
structure created and owned by an instance of KXMLGUIBuilder.

I've been looking at the use of %ConvertToSubClassCode in PyQt and I'm 
struggling to understand how it works. Could you give an example for this 
situation?

What determines whether a function is a factory function?
