This is of course unacceptable behavior.

In GTK if you want this you simply disable shrinking, expanding, 
filling, that would produce this kind of mess.

The proper approach in case you do not want to resize children is to use 
Gtk_Scrolled_Window as the top-level container.

masochistic user satisfaction... (:-)) ]

You can always catch size allocation signals and hide widgets you wanted.

[ GTK 3 changed the protocol a bit from one in GTK 2, they added 
preferable widget sizes, but in essence these details are irrelevant for 
Gtk_Fixed. ]
