as I understand it any showing of the window (if it was partially hidden
for instance) is an expose event

>From the drawing area tutorial:

When a widget is first shown, or when it is covered and then uncovered
again it needs to redraw itself. Most widgets have code to do this, but
the DrawingArea does not, allowing you to write an expose event signal
handler to determine how the contents of the widget will be drawn.
