So How can I combine the WIDGET_BASE and BASEWIDGET object into the same application.

Yeah, I'm afraid it is all or nothing when you switch to the Catalyst
Library. *Everything* has to be an object over there. It *can* drive you
crazy until you build up enough objects in your own library. There are a
number of advantages to doing so, however.

The problem really has to do with how widget events get propagated in
widget objects. The way this has to be done makes it impossible (I
believe) to build a hybrid system.

Cheers,

David
