TPanel is not for drawing, use TPaintBox (or TForm if you prefer to draw on the whole form) for that.

As its name suggests, TPanel is a container of controls. Not a container of arbitrary drawing. You can still however paint to it, by creating a descendant control and override the Paint method. Probably through this you'll understand why it has no OnPaint event (which a control for true drawing has).

use BGRAControls TBGRAVirtualScreen (like TPanel) or TBGRAGraphicControl (like TPaintBox).
