protected void paintFigure(
Graphics graphics)
-
Description copied from class:
Figure
- Paints this Figure's primary representation, or background. Changes made to the
graphics to the graphics current state will not affect the subsequent calls to
Figure.paintClientArea(Graphics) and
Figure.paintBorder(Graphics) . Furthermore, it is safe
to call graphics.restoreState() within this method, and doing so will
restore the graphics to its original state upon entry.
