layoutCompoundLabel

public static java.lang.String layoutCompoundLabel(javax.swing.JComponent c,
                                                   java.awt.FontMetrics fm,
                                                   java.lang.String[] text,

                                                   java.awt.Rectangle viewR,
                                                   java.awt.Rectangle iconR,

                                                   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.

layoutCompoundLabel

public static java.lang.String layoutCompoundLabel(java.awt.FontMetrics fm,
                                                   java.lang.String[] text,
                                                   javax.swing.Icon icon,
                                                   int verticalAlignment,

                                                   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.
