Re: "widget_class->event" not working

["Patrick M. Rutkowski" <rutski89 gmail com>]

Actually, I just figured it out a few moments ago. Adding the
following to realize() beings to fix things:

GTK_WIDGET_SET_FLAGS(widget, GTK_CAN_FOCUS);

I start to get keyboard events and such.

However, there's another problem now! Even with GTK_CAN_FOCUS, I still
don't get GDK_MOTION_NOTIFY events, or even mouse button press events.

Here's another test case to instated illustrate that problem. This
time, "IT WORKS!" only prints if the event is somehow mouse related:

See if you can get that one to print, I can't
