void gdk_window_process_updates ( GdkWindow* window, gboolean update_children )
Sends one or more expose events to
window. The areas in each
expose event will cover the entire update area for the window (see
gdk_window_invalidate_region() for details). Normally GDK calls
gdk_window_process_all_updates() on your behalf, so there’s no
need to call this function unless you want to force expose events
to be delivered immediately and synchronously (vs. the usual
case, where GDK delivers them in an idle handler). Occasionally
this is useful to produce nicer scrolling behavior, for example.
