import javax.swing.JList; //导入方法依赖的package包/类
private void showJList (JScrollPane view, Point pt) {
JList list = (JList) view.getViewport().getView();
Point p = SwingUtilities.convertPoint(view, pt.x, pt.y, list);

hide();
return;
}

row);
//GetCellBounds returns a width that is the
//full component width; we want only what
//the renderer really needs.
