Invalidate or refresh ?

[ER]

Hi -

What is better or what should I use, Invalidate or refresh ?

For this gaming I'm working on, though not much going on right now,
I get 31-32 fps if I use GameCanvas.Refresh. I'll get 48-49 fps if I
use
GameCanvas.Refresh. (Mac OS)


Thanks.

Invalidate marks the item as dirty so it's repainted the next time the OS finds it necessary. Refresh forces the redraw immediately. Usually invalidate is preferred.

You've answered you own question, pretty much.

Invalidate flags and defers until a redraw happens in the normal course of
events, which may draw more than one invalidated area (efficiency).

Refresh is 'stop everything and draw just this, now!'

Gauge the result and favor invalidate unless you notice a delay.
