The 'filled' property

0 or 1

Valid for: Line, Rectangle, RoundRect, Arc

For a graphic object, the filled property indicates whether the object is filled with the foreground color (1), or not (0). The default is 0. This property can be set for a Line, but is ignored. For an arc which does not describe a full 360 degrees, the effect is to display a filled wedge (such as you would have in a 'pie' chart).
