Yeah I know what you mean: there's no documentation for drawing_area.
But actually drawing area is the most primitive widget because you have
to handle all the events yourself, and you can draw anything on it
using the GDK library which has all the functions for drawing shapes. I
have made a program using the drawing_area widget to display OpenGL
rendering, and most of the things I need to remember are that

- the "configure" event is sent when the widget is first appeared, and
- the "expose" event is sent when the widget needs to be redrawn.

Other than that, there's nothing too much about the drawing_area
widget... you just draw whatever you like on it. Oh and I got these
information from a book about programing in GNOME, and from the code
examples that come from GtkGlExt, which lets you make OpenGL renders in
a GTK widget.

I don't remember the name of that GNOME book right now, but if you are
interested I can search it for you.

Bye.

Jack
