Re: GDK: Window resizing

["Stefan Andersen" <zingo zingo org>]

Thanks
This helps a bit...
Now I resize my window, and generate a "configure" and a "expose" event... It seems to work much better
but not all the way... My biggest questionmark now is why the width is not changed in the resize.... is
there some
"feature" in gtk/gdk that make the button in the arrow example not be resized in x only in y?
