The Gtk 1.1 series has a much nicer way to do all this, by the way - and
it's going stable in a month or two. So you may want to be thinking about
that.

You mean a horizontal scrollbar?

The problem is that GtkWindow does not expand to give children as much
space as they want, although most of the containers do. You can see why -
users would probably get kind of irritated if windows changed all around
by themselves. What if the user has a 640x480 display, and the window kept
growing too big? 

However, if you know for sure your window won't get too big, you can just
expand it with gtk_widget_set_usize(). However, I would avoid growing it
beyond 600x400 or so. And in general, scrollbars are probably better since 
self-resizing windows are freaky from a UI standpoint.

It's useful to know (if you don't) that you can pass -1 for either usize
arg to leave it unchanged, since it sounds like only the horizontal
matters to you.
