Description
TTBCustomDrawEvent is the type of a toolbar's TToolBar.OnCustomDraw event handlers.
Sender is the toolbar that needs to be painted.
ARect indicates the dimensions of the toolbar on the canvas.
Leave DefaultDraw as True if the toolbar should continue with the normal painting process. Set DefaultDraw to False if the OnCustomDraw event handler has completely painted the toolbar.
