I'm using Delphi and I'm building my own label component with class TControl.
Before I paint the text according to the properties (such as caption, font, etc.) I want to clear paint rect like there is nothing at the place of component. I mean I want to make it like a glass so that the other components behind it will be displayed; and then paint the text. What should I do to paint other components that are placed behind my label to it?
