[wxPython-users] Drawing connectors between two buttons

Hi,

Yeah, I made this adjustment as soon as I noticed I had to draw a line between
(0,20) and (0,20) :).

-There is space between the buttons, so the line drawing comes somewhat
difficult when operating with multiple frames. Thanks for the point and nice
example! I just would prefer a pancake right now. :)

-Those panels were there only for the layout. I have started to work with
GridBagSizer, I don't know whether it would be easier only to use horizontal
BoxSizer and add there three vertical BoxSizers??

Anyway, thanks for help,
best,
Jarno
