I've a complex GUI with multiple widgets, include over 300 LED widgets. Periodically, I receive update information (for all the widgets).
How do I disable the updating of the GUI until I've done all my "setText" and "setLED" and "setWhatever" calls? Normally, each of these calls would trigger a GUI update -- thats a lot of unecessary updating that causes noticeable flicker.
