I don't understand why I have to deactivate "Overwrite existing sources".  That doesn't make sense to me.  I've added some extra widgets to the design and now I want to regenerate sources, so I need to overwrite them.
If you interpret this option that way, then it would not be too useful as only the first time any code would be written.
I think, the label should be changed to something like "Overwrite user code" together with some better tooltip help, though.

I ended up sub-classing the app and binding the widgets, as I have asyncio coroutines working at that level that need to interact with the gui.

Still wxglade is generates the print statement that outputs to stdio, whether you want it or not.  If it is commented out or deleted, it gets regenerated on the next regeneration of the sources.
This way, you have two handlers, both bound to the event and therefore also both are executed:
 - generated by wxGlade in the generated class and bound by the generated class
 - written and bound by you in your application

So either don't define a handler in wxGlade or override the generated handler in a derived class.
Probably I should have written in my last message:

class ExampleFrame(ExampleGUI.ExampleFrame):
    def __init__(self, app):
        self.app = app
        ExampleGUI.ExampleFrame.__init__(self, None, wx.ID_ANY, "")

    # XXX override generated handlers here
    def on_button(self, event):
        #print("Event handler 'on_button' not implemented!")
        self.app.do_something_useful()
        event.Skip()

Regards,

Dietmar
