public void process_updates (bool update_children)
Warning: process_updates is deprecated since "3.22".
Sends one or more expose events to this.
The areas in each expose event will cover the entire update area for the window (see invalidate_region for details). Normally GDK calls 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.
