[Pythoncard-users] mouse event failures (was Re: tree)

[John H. <ec...@ya...>]

I'm now taking a closer look at my tree control program and try to figure out why somethings don't work right.

In a native wxPython set up, when you get a dragEnd event, you should be able to know the target from:

        target = evt.GetItem()


For Pythoncard, you get a "MouseEvent" object has no attribute xxx.  In addition, you can't even do a evt.Veto() for the same reason.

Something is wrong here.
