the first argument to the handler of a signal emitted by a
widget-based event is the widget in which the event happened. always.

you can't draw from a configure event. Only from an expose event.

no. configure_event will be emitted for each widget, every time it
needs to be "configured" (which mostly means "sized"). expose_event
will be emitted for every widget that needs redrawing, whenever they
need redrawing.
