import gtk class StickyWindow(gtk.Window): def __init__(self): super(StickyWindow, self).__init__() label = gtk.Label("Hello") label.show() self.add(label) self.set_default_size(200, 200) self.set_property('accept-focus', False) self.show() self.stick() def main(self): gtk.main() if __name__ == "__main__": sticky = StickyWindow() sticky.main() -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/948371 Title: After closing last window on workspace, the keyboard doesn't react at any keypress To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/948371/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
