Class ImageList

  • All Implemented Interfaces:
    Scrollable
    public class ImageList
extends ListBox
    Implements a ListBox where the items are images. Next an example of how to use this class as a combobox color chooser: 
     ImageList list = new ImageList();
 list.add( ADD AT LEAST ONE IMAGE SO THE CORRECT SIZE CAN BE COMPUTED );
 add(foreCombo = new ComboBox(list), CENTER, BOTTOM);
    If you don't add at least one image before calling add/setRect, you must compute the preferred size yourself.
