JTree放入JSplitPane实例

JTree放入JSplitPane范例

范例1

import javax.swing.JFrame;import javax.swing.JLabel;import javax.swing.JSplitPane;import javax.swing.JTree;import javax.swing.event.TreeSelectionEvent;import javax.swing.event.TreeSelectionListener;public class JTreeTest extends JFrame {    private JSplitPane split = new JSplitPane();    private JTree tree = new JTree();    private JLabel label = new JLabel();    public JTreeTest() {        this.getContentPane().add(this.split);        this.split.setLeftComponent(this.tree);        this.tree.addTreeSelectionListener(new TreeSelectionListener() {            public void valueChanged(TreeSelectionEvent e) {                label.setText(tree.getSelectionPath().getLastPathComponent().toString());            }        });        this.split.setRightComponent(this.label);    }    /**     * @param args     */    public static void main(String[] args) {        JTreeTest jt = new JTreeTest();        jt.setVisible(true);        jt.setSize(300, 200);        jt.setDefaultCloseOperation(EXIT_ON_CLOSE);    }}

范例2：

package com.boomlink.report.gui.chart.treetest.jsplitpane;

import javax.swing.*;import javax.swing.event.TreeSelectionEvent;import javax.swing.event.TreeSelectionListener;

public class TestJTree {

?/**? * @param args? */?public static void main(String[] args) {??JFrame fr = new JFrame();??fr.setSize(300, 500);??fr.setDefaultCloseOperation(3);??JSplitPane jp = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT);??fr.getContentPane().add(jp);??JTree jt = new JTree();??jp.add(jt, JSplitPane.LEFT, 0);??JTextArea ja = new JTextArea();??jp.add(ja, JSplitPane.RIGHT, 1);??// fr.getContentPane().add(jt);??fr.setVisible(true);??jt.addTreeSelectionListener(new MyTreeSelectionListener(ja, jt));?}

}

class MyTreeSelectionListener implements TreeSelectionListener {?JTextArea ja;?JTree jt;

?public MyTreeSelectionListener(JTextArea ja, JTree jt) {??this.ja = ja;??this.jt = jt;?}

?public void valueChanged(TreeSelectionEvent e) {??ja.setText(jt.getSelectionPath().getLastPathComponent().toString());

?}

}
