A panel is a widget that displays arbitrary graphics drawn outside of Tk. An application is free to use any image or mask that it chooses to create; the panel will display the contents of the image through the mask (see draw(2)).

A panel widget will not display anything until its image has been set using putimage (see tk(2)).
