resizing a drawingarea

[Kees Kling <ckling upcmail nl>]

Hi guys,

I'm missing something simple, but I have a small problem with the 
drawingingarea.

I have a widget derived from Gtk::DrawingArea. This widget is placed in 
a window. So far so good, but when I resize the window, the size of the 
drawingarea stays the same. What must I do about that.

Thanks
