Problems using SetDropTarget

wxPython Users

Hello,

If I run this code I do get a segmentation fault on exit.
I figured out, that this happens only when using SetDropTarget more than once.
Did I miss something?

Cheers

Hello,

looks like I found the reason, the drop target instance cannot be reused,
instead it is needed to recreate it every time you need to assign it
to a different control. Not sure if this works as expected but if so,
maybe a hint in the documentation might be useful.

Thanks
