JList元素上的双击事件

Question

我有JList一个DefaultListModel。

如何在JList双击事件中做出反应？

Answer 1

String[] items = {"A", "B", "C", "D"};
JList list = new JList(items);

list.addMouseListener(new MouseAdapter() {
    public void mouseClicked(MouseEvent evt) {
        JList list = (JList)evt.getSource();
        if (evt.getClickCount() == 2) {

            // Double-click detected
            int index = list.locationToIndex(evt.getPoint());
        } else if (evt.getClickCount() == 3) {

            // Triple-click detected
            int index = list.locationToIndex(evt.getPoint());
        }
    }
});
