Hello
Can you tel me how PF_InvalidateRect ( and painting engine in general ) works?
PF_InvalidateRect clears rectangle specified on the context specified. Than I sould set PF_EO_UPDATE_NOW flag to the ouput flags for redrawing. Than, I guess, u.draw.update_rect is those rectangle which was cleared. It's clear.
But if I call PF_InvalidateRect twice? What will I recieve at draw event?
Thank you
