Daniel, I played with your code last night at home. I modified it so it actually loads pictures in the left and right Gtk.Image. I found that when I tabbed through the controls in the window that the focus_in and focus_out methods were invoked. However, when I tried to change the focus by clicking on either image nothing happened. Before trying this I changed View Slides to eliminate the event box and the Activity still doesn't work. I added code like this: self.image1.set_events(Gdk.EventMask.KEY_PRESS_MASK | Gdk.EventMask.BUTTON_PRESS_MASK) to your example but it had no effect. You can tab into an Image but you can't make it take the focus by clicking on it. This link suggests that the event box is necessary: <a href="http://stackoverflow.com/questions/14861503/catching-button-click-on-gtk-image-python-gtk3">http://stackoverflow.com/questions/14861503/catching-button-click-on-gtk-image-python-gtk3</a> I'm going to fool with this some more this weekend.
