public class JELabelUI
extends javax.swing.plaf.LabelUI
implements java.beans.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 java.lang.String layoutCL(javax.swing.JLabel label,
                                    java.awt.FontMetrics fontMetrics,
                                    java.lang.String text,
                                    javax.swing.Icon icon,
                                    java.awt.Rectangle viewR,
                                    java.awt.Rectangle iconR,
                                    java.awt.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.

SwingUtilities.layoutCompoundLabel(javax.swing.JComponent, java.awt.FontMetrics, java.lang.String, javax.swing.Icon, int, int, int, int, java.awt.Rectangle, java.awt.Rectangle, java.awt.Rectangle, int)

paintEnabledText

protected void paintEnabledText(javax.swing.JLabel l,
                                java.awt.Graphics g,
                                java.lang.String s,
                                int textX,
                                int textY)

Paint clippedText at textX, textY with the labels foreground color.

paint(java.awt.Graphics, javax.swing.JComponent), paintDisabledText(javax.swing.JLabel, java.awt.Graphics, java.lang.String, int, int)

paintDisabledText

protected void paintDisabledText(javax.swing.JLabel l,
                                 java.awt.Graphics g,
                                 java.lang.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(java.awt.Graphics g,
                  javax.swing.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.

drawString

public static void drawString(java.awt.Graphics g,
                              java.lang.String text,
                              int underlinedChar,

                              int y)

Draw a string with the graphics g at location (x,y) just like g.drawString would. The first occurrence of underlineChar in text will be underlined. The matching algorithm is not case sensitive.

drawStringUnderlineCharAt

public static void drawStringUnderlineCharAt(java.awt.Graphics g,
                                             java.lang.String text,
                                             int underlinedIndex,

                                             int y)

Draw a string with the graphics g at location ( x,y) just like g.drawString would. The character at index underlinedIndex in text will be underlined. If index is beyond the bounds of text (including < 0), nothing will be underlined.

Parameters:

g - Graphics to draw with

text - String to draw

underlinedIndex - Index of character in text to underline

x - x coordinate to draw at

y - y coordinate to draw at
