rendering actions in a combo box








When I add an array of action-objects (the class extends AbstractAction)







to a combo box, I do receive the action performed events, great!







But the combo box items show the long string of the action object, of course!








How to render that string in a way that only the Action.NAME appears?








I was experimenting a little, but could not make it to work:












Java Code:











private class ComboRenderer2 extends BasicComboBoxRenderer {

@Override
public Component getListCellRendererComponent(JList list,
Object value, int index, boolean isSelected,
boolean cellHasFocus) {
super.getListCellRendererComponent(list, value, index,
isSelected, cellHasFocus);
final Object fntObj = value;
Action sa = null;
sa = (Action) fntObj;
String s = (String) sa.getValue(Action.NAME);
// ??
return this;
}
}
