Description
Renders the image of a custom control.
The Paint method for TCustomControl does nothing other than provide the interface for a method that responds to WM_PAINT messages. Paint is called by the PaintWindow method, after that method has supplied the Canvas with the handle to a device context. When creating a custom control, always override Paint to draw the image of the control.
Tip: To determine which portions of the control's canvas need to be repainted when Paint is called, use the ClipRect property of the canvas.
