我使个初学者,对jbuilder和java还很陌生,请说得详细些,谢谢:)
程序代码如下:
public class Frame1 extends JFrame {
private JPanel contentPane;
private BorderLayout borderLayout1 = new BorderLayout();
private JPanel jPanel1 = new JPanel();
private XYLayout xYLayout1 = new XYLayout();
private JTree jTree1 = new JTree();

private JMenu jMenu1 = new JMenu();
private JMenu jMenu2 = new JMenu();
private JMenuItem jMenuItem1 = new JMenuItem();
private JMenuItem jMenuItem2 = new JMenuItem();
private JMenuItem jMenuItem3 = new JMenuItem(); //Construct the frame
public Frame1() {
enableEvents(AWTEvent.WINDOW_EVENT_MASK);
try {
jbInit();
}
catch(Exception e) {
e.printStackTrace();
}
}
//Component initialization
private void jbInit() throws Exception {
//setIconImage(Toolkit.getDefaultToolkit().createImage(Frame1.class.getResource("[Your Icon]")));
contentPane = (JPanel) this.getContentPane();
contentPane.setLayout(borderLayout1);
this.setSize(new Dimension(400, 300));
this.setTitle("Frame Title");
this.addKeyListener(new java.awt.event.KeyAdapter() {
});
//this.addjPopupMenu(jPopupMenu1);
jPanel1.setLayout(xYLayout1);
jButton1.setText("ok");
jButton1.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(ActionEvent e) {
jButton1_actionPerformed(e);
}
});
contentPane.setToolTipText("");
jPanel1.setToolTipText("");
jPanel1.addMouseListener(new java.awt.event.MouseAdapter() {
//public void mouseClicked(MouseEvent e) {
//jPanel1_mouseClicked(e);
//}
});
jPopupMenu1.setInvoker(this);
jPopupMenu1.addMouseListener(new java.awt.event.MouseAdapter() {
public void mouseClicked(MouseEvent e) {
jPopupMenu1_mouseClicked(e);
}
});
jMenu1.setText("open");
