TControl.Invalidate Method
TControl Class | TControl Members | Controls Namespace | Description | See Also
Collapse All

Completely repaint control.

Pascal
procedure Invalidate; virtual;
C++
virtual __fastcall Invalidate();
Description

Use Invalidate when the entire control needs to be repainted. When more than one region within the control 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.
