In GNUstep you have two different window view structures depending on 
the value of the GSBackHandlesWindowDecoration user default. When set to 
YES we leave the window decoration to the window manager, when set to NO 
GNUstep gui handles that itself.

The view structure is something like this:

The window has a slot _wv that contains the window decorator view, this 
is either of the class GSBackendWindowDecorationView, which leave the 
window decoration to the window manager, or 
GSStandardWindowDecorationView. The later draws the window decoration 
itself. This view contains the menu, the toolbar and the content view of 
the window. Within the content view everything should be the same as on 
MacOSX.

Does this answer some of your questions?
