I have tried the mpl and glade examples and tried different approaches
from the net, but I can only get button_press_event to work with a matplot
canvas. key_press_event does not work using gtkagg for GUI.
Is this due to the gtk builder 2.16? I mean does the main window steal the
key_presses or something?
I had previously tried an example without a gtk gui (don't remember the
example). There a callback was connected and it could get events
containing both mouse click and keypress. I mean if I pressed the mouse
button while keeping doen say 'e' I could get form event.key that 'e' was
pressed when I click the mouse.
I have to use gtk for the rest of the GUI so when I tried to pack the
canvas into gtk I got the problem that callbacks and connections didn't
work. i guess it has to do with that gtk has it's own callback system.
If anybody has some example code, tips or tricks, I would very much
appreciate that. I cannot at the moment provide an example code due to
project deadline, but will do afterwards.
thanks in advance
