1. You can obtain any widget's GdkWindow by pointer widget->window.
2. If I'm not mistaken gtk_widget_get_root_window returns the default 
root window of screen, not the root window of your application.
3. You can get XID of your app's main window, but keep in mind that the 
gdk window will be created after widget will get realized. You probably 
will need to connect to "realize" event.

                memset(&ev, 0, sizeof(ev));
