                      int cx,
                      int cy)

Sets the bounds of the component. This gives the opportunity for the component to change its size.

Specified by:

setBounds in interface IDesignerControl

Performs a pre-paint.

Specified by:

prePaint in interface IDesignerControl

postPaint

public void postPaint(PanelDesignerControl controller,
                      Graphics2D g,
                      JComponent c,
                      int cx,
                      int cy)
