Re: [Pythoncard-users] PDFWindow

I got a little further. Turns out I had to pass down an ID of -1. Not sure if it's working yet but at least it's behaving the same as an wxWindow example - the file is loaded but I'm not seeing anything - but I believe the binding itself is working.

# the event binding would be specific to a component
# since on dispatch command overrides something like mouseClickEvent

# need to look at whether self.command has a value and then bind
# with ButtonMouseClickEvent.binding if that isn't already bound

# need to avoid double binding
# also binding shouldn't be order-specific
# so how to avoid binding mouseDrag to _dispatch
# if mouseMove is already bound or if binding mouseMove
# not rebinding if mouseDrag is already bound
# perhaps MouseDragEvent keeps a reference to MouseMoveEvent
# and that is inserted into boundEvents, then we check boundEvents
