update is GUI_APP_END::eval("update "); end;
-- Used to bring the entire world up-to-date. It flushes pending
-- output to the display and waits for the server to process the
-- output and return errors or events, handles all pending events
-- of any sort and repeats this set of operations until there are
-- no pending events, no pending handlers and no operations still
-- outstanding ( from Tk man page)
update_idletasks is GUI_APP_END::eval("update idletasks"); end;
-- Same as update, but no new events or errors are processed -
-- only the when idle handlers are invoked.
