Hi,
I'm working on porting my projects to Gtk3 and PyGobject3. However, I run into
a nasty issue.
I subclass Gtk.DrawingArea in order to provide view functionality for a Gaphas
canvas. For this I override some signals. Here's a minimal example that crashes
on OS X:
from gi.repository import Gtk
from gaphas import Canvas, GtkView, View
class MyDrawingArea(Gtk.DrawingArea):
def do_realize(self):
Gtk.DrawingArea.do_realize(self)
def main():
win = Gtk.Window()
view = GtkView()
win.add(view)
win.show()
view.show()
win.connect('destroy', Gtk.main_quit)
Gtk.main()
if __name__ == '__main__':
main()
Below I passed the information that OS X provides after a crash. Notice the
topmost stack frame. It points to an address that is quite bigger than any of
the other frames.
Is this some simple 32 bit vs 64 bit incompatibility?
I compiled the sources using Homebrew
(https://github.com/amolenaar/homebrew/tree/pygtk). As far as I know there is
no Gtk3/PyGobject3 configuration in jhbuild yet.
I want to look into this issue myself, only I need a starting point.
Any suggestions?
Regards,
Arjan
