e774. Creating a JList ComponentBy default, a list allows more than one item to be selected. Also, the selected items need not be contiguous. To change this default, see e781 Setting the Selection Mode of a JList Component.A list selection event is fired when the set of selected items is changed (see e784 Listening for Changes to the Selection in a JList Component). // Create a list with some items String[] items = {"A", "B", "C", "D"}; JList list = new JList(items);The items can be arbitrary objects. The toString() method of the
objects is displayed in the list component.
// Create a list with two items - "123" and "Sun May 19 21:15:38 PDT 2002" Object[] items2 = {new Integer(123), new java.util.Date()}; list = new JList(items2);By default, a list does not automatically display a scrollbar when there are more items than can be displayed. The list must be wrapped in a scroll pane: JScrollPane scrollingList = new JScrollPane(list);
