Sun Oct 3 18:13:44 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_reset_shapes_recurse): Fix a reference to window_private->destroyed. * gtk/gtkplug.c (gtk_plug_realize): Fix up a direct (ugly) setting of an internal GdkWindow member to use a _slightly_ cleaner macro. * gdk/gdkprivate.h: Split GdkWindowPrivate into GdkDrawablePrivate and GdkWindowPrivate. Add extra macros for accessing GDK_DRAWABLE_ components. * *.[ch]: Massive adjustments for the above, use the new macros in a lot of places.
