- All Implemented Interfaces:
- EventListener, PropertyChangeListener
- Direct Known Subclasses:
- MetalLabelUI
- public class BasicLabelUI
- extends LabelUI
- implements PropertyChangeListener
A Windows L&F implementation of LabelUI. This implementation
is completely static, i.e. there's only one UIView implementation
that's shared by all JLabel objects.

layoutCL
protected String layoutCL(JLabel label,
FontMetrics fontMetrics,
String text,
Icon icon,
Rectangle viewR,
Rectangle iconR,
Rectangle textR)
- Forwards the call to SwingUtilities.layoutCompoundLabel().
This method is here so that a subclass could do Label specific
layout and to shorten the method name a little.

paintEnabledText
protected void paintEnabledText(JLabel l,
Graphics g,
String s,
int textX,
int textY)
- Paint clippedText at textX, textY with the labels foreground color.

paintDisabledText
protected void paintDisabledText(JLabel l,
Graphics g,
String s,
int textX,

- Paint clippedText at textX, textY with background.lighter() and then
shifted down and to the right by one pixel with background.darker().

paint
public void paint(Graphics g,
JComponent c)
- Paint the label text in the foreground color, if the label
is opaque then paint the entire background with the background
color. The Label text is drawn by paintEnabledText() or
paintDisabledText(). The locations of the label parts are computed
by layoutCL.
