您必须实现

ListCellRenderer(或扩展

DefaultListCellRenderer)并使用getListCellRendererComponent方法返回带有图标的Jlabel.

例：

public class IconListRenderer extends DefaultListCellRenderer {

public Component getListCellRendererComponent(

JList list, Object value, int index,

boolean isSelected, boolean cellHasFocus) {

JLabel label = (JLabel) super.getListCellRendererComponent(

list, value, index, isSelected, cellHasFocus);

Icon icon = this.getIcon(list, value, index, isSelected, cellHasFocus)

label.setIcon(icon);

return label;

}

protected Icon getIcon(

JList list, Object value, int index,

boolean isSelected, boolean cellHasFocus) {

// how do I get icon?

}

}

您必须实现getIcon方法.
