public void freeze_toplevel_updates_libgtk_only ()
Warning: freeze_toplevel_updates_libgtk_only is deprecated since "3.16".
Temporarily freezes a window and all its descendants such that it won't receive expose events.
This symbol was never meant to be used outside of GTK+
The window will begin receiving expose events again when thaw_toplevel_updates_libgtk_only is called. If freeze_toplevel_updates_libgtk_only has been called more than once, thaw_toplevel_updates_libgtk_only must be called an equal number of times to begin processing exposes.
This function is not part of the GDK public API and is only for use by GTK+.
