as of gtk+ 2.18:

	s/Many/Some/

non-top level widgets (where "top level" here mostly means: GtkWindow
and sub-classes, even though GtkMenu has to have a real X11 window
associated with it for stacking purposes) that used X11 windows through
GDK for event handling and drawing purposes now do not have those X11
windows any more - though they maintain the GdkWindow object for
internal state handling and for ABI compatibility.

usually, a GdkWindow is not associated to an X11 Window unless you
explicitly require a XID out of it - at which point GDK will create a
native Window and hand over to you its XID.
