On Linux (at least with Gnome/Metacity) you can use:

procedure Set_Decorated
   (Window             : access Gtk_Window_Record;
    Setting            :        Boolean := True);

By default, windows are decorated with a title bar, resize
controls, etc. Some window managers allow GtkAda to disable these 
decorations, creating a borderless window. If you set the decorated 
property to False using this function, GtkAda will do its best to 
convince the window manager not to decorate the window.

This gives you a borderless window, i.e. no resize bar or title bar. 
Doesn't seem to work with Windows.

On Windows but not on Linux (tried with Gnome, XFCE and Fluxbox) you can 
use Gdk.Windows.Set_Decorations:

Show (Window);
Gdk.Window.Set_Decorations (Get_Window (Window), Decor_Border or 
Decor_Title);

This gives a window with frame and title bar. Has to be called after 
Show. This works on Windows but not with libglade.
