procedure Invalidate; virtual; abstract;
Unit
TeCanvas
Description
Use Invalidate when the entire canvas needs to be repainted. When more than one region within the canvas needs repainting, Invalidate will cause the entire window to be repainted in a single pass, avoiding flicker caused by redundant repaints. There is no performance penalty for calling Invalidate multiple times before the control is actually repainted.
