Hi! We are creating an application using GTKMM. We are using a lot of Gtk::Button and Gtk::DrawingArea controls and connecting expose_event() and button_press_event() on them using standard gtkmm code. Application works fine and react as wanted. Unfortunately, we noticed some random crash a while ago, and since release is near I was assigned to fix them. I don't know exactly what cause the crash, but if I click on every button randomly the fastest I can for 2-3 minutes, it always crash with the same problem.

Judging from the stack at #6, it have something to do with Gtk::Widget_Class::button_press_event_callback. Since every callback we have works fine, I wonder what it could be. Is there a problem is we manage to click 2 buttons with callback in the same gtk iteration? Can this be some gtk multi-thread problem? We only use one for the UI. -- View this message in context: http://www.nabble.com/Crash-in-Gtk%3AMain%3A%3Arun-%28callback-signal-problem%29-tp23406686p23406686.html Sent from the Gtkmm mailing list archive at Nabble.com. _______________________________________________ gtkmm-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtkmm-list
