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.

Method Detail

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,
                                 int textY)

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.
