J2SE 中JTree 事件问题

Question

               我做了了一个JTreee 里面有很多子节点 我想为那些子节点添加事件 双击一个子节点 弹出了一个对话框  也就是一个卧已经写好的 界面或者窗体  希望你们用个例子帮我解答

Answer 1

以前写的``````jTree1.addTreeSelectionListener(new TreeSelectionListener() //给树加事件
{
public void valueChanged(TreeSelectionEvent evt)
{
String str=jTree1.getLastSelectedPathComponent().toString(); //得到你选择的节点
if(str.equals("J1001"))//如果选择的是J001节点
{
//要做的事情
}
if(str.equals("J1002"))//如果选择的是J001节点
{
//要做的事情
}
}
});

Answer 2

tree.addMouseListener(new MouseAdapter(){
                            public void mousePressed(MouseEvent evt){
                                if(e.getClickCount() == 2){
                                    JTree t = (JTree) evt.getSource();
                                    int row = t.getRowForLocation(evt.getX(),evt.getY());
                                    if (row != -1) {
                                        TreePath path = t.getPathForRow(row);
                                        TreeNode node = (TreeNode)path.getLastPathComponent();
                                        ... // do something
                                    }
                                }
                            }
                        });
