I use emWin graphical libraries, but I think the situation is similar to 
other similar toolkit.

Even with these libraries, you can choose an event-based or a 
refresh-based approach. Yes, they are usually event-based, but this is 
limited to the GUI: the user press a button and an event is trigger (a 
callback is called).

Anyway the programmer can choose to update values on the display at a 
regular rate or when an event (from the field/bus, not from the GUI) is 
triggered.

I know... I know.
