public final class MultiLineLabelUI
extends javax.swing.plaf.basic.BasicLabelUI

* Author: Zafir Anjum * http://codeguru.earthweb.com/java/articles/198.shtml * * Use multi-line text in a JLabel. * To enable multi-line in a JLabel we have to specify our own LabelUI * class that will render the multiple lines. Although the code shown * below seems quite long, most of it is actually Swing code being reused. * *

computeMultiLineDimension

                                                           java.lang.String[] strs)

layoutCompoundLabel

public static java.lang.String layoutCompoundLabel(java.awt.FontMetrics fm,
                                                   java.lang.String[] text,
                                                   javax.swing.Icon icon,
                                                   int verticalAlignment,
                                                   int horizontalAlignment,
                                                   int verticalTextPosition,
                                                   int horizontalTextPosition,
                                                   java.awt.Rectangle viewR,
                                                   java.awt.Rectangle iconR,
                                                   java.awt.Rectangle textR,
                                                   int textIconGap)

Compute and return the location of the icons origin, the location of origin of the text baseline, and a possibly clipped version of the compound labels string. Locations are computed relative to the viewR rectangle. This layoutCompoundLabel() does not know how to handle LEADING/TRAILING values in horizontalTextPosition (they will default to RIGHT) and in horizontalAlignment (they will default to CENTER). Use the other version of layoutCompoundLabel() instead.

layoutCompoundLabel

public static java.lang.String layoutCompoundLabel(javax.swing.JComponent c,
                                                   java.awt.FontMetrics fm,
                                                   java.lang.String[] text,
                                                   javax.swing.Icon icon,
                                                   int verticalAlignment,
                                                   int horizontalAlignment,
                                                   int verticalTextPosition,
                                                   int horizontalTextPosition,
                                                   java.awt.Rectangle viewR,
                                                   java.awt.Rectangle iconR,
                                                   java.awt.Rectangle textR,
                                                   int textIconGap)

Compute and return the location of the icons origin, the location of origin of the text baseline, and a possibly clipped version of the compound labels string. Locations are computed relative to the viewR rectangle. The JComponents orientation (LEADING/TRAILING) will also be taken into account and translated into LEFT/RIGHT values accordingly.
