Question

在JPanel中添加JTree，在JTree中的子节点中添加监听ActionListener

Answer 1

我在JPanel中添加了一个JTree，那如何在JTree中的子节点中添加监听ActionListener

Answer 2

http://www.diybl.com/course/3_program/java/javajs/2007114/83434.html还有其他监听器, 搜一下

Answer 4

给JTree添加监听，然后判断最后选中的节点
或者很据鼠标的位置判断节点

Answer 5

MyTreeListener mtl = new MyTreeListener();jtree.addTreeSelectionListener(mtl);
jtree.addTreeExpansionListener(mtl);private class MyTreeListener implements TreeExpansionListener,
    TreeModelListener, TreeSelectionListener {}用这个类就好了

Answer 6

那在
public void valueChanged(TreeSelectionEvent e) {

}
这个方法中如何判断监听不同的对象啊import java.awt.*;
