x - the X coordinate
y - the Y coordinate
w - width of the border
h - height of the border

paint

public void paint(Graphics g, JComponent c)

Overrides:
paint in class ComponentUI
Parameters:
g - the Graphics object used for painting
c - the component being painted
See Also:
  • paint(SynthContext,Graphics)

paint

protected void paint(SynthContext context, Graphics g)
Paints the specified component.
Parameters:
context - context for the component being painted
g - the Graphics object used for painting
See Also:
  • update(Graphics,JComponent)

createLayoutManager

protected LayoutManager createLayoutManager()
