[求助]javax.swing.JTextField控件的右键菜单问题

[boostspirts]

需求:在组件上单击右键,要有Copy和Paste的功能.
具体实现:
成功的方法:继承自java.awt.TextField
public class TextFieldLabel extends java.awt.TextField implements MouseListener, FocusListener{
...
...
public void setRightButtonEnable(boolean rightButtonEnable)
{
this.rightButtonEnable = rightButtonEnable;
if (rightButtonEnable == true) {
enableEvents(AWTEvent.MOUSE_EVENT_MASK);
} else {
disableEvents(AWTEvent.MOUSE_EVENT_MASK);
}
}
...
...
}

失败的方法:继承自javax.swing.JTextField
public class ScTextFieldLabelSwing extends javax.swing.JTextField implements MouseListener, FocusListener
{
....
....
public void setRightButtonEnable(boolean rightButtonEnable)
{
this.rightButtonEnable = rightButtonEnable;
if (rightButtonEnable == true) {
enableEvents(AWTEvent.MOUSE_EVENT_MASK);
} else {
disableEvents(AWTEvent.MOUSE_EVENT_MASK);
}
}
...
...
}

问题:同样的setRightButtonEnable方法在swing中为什么不好用.而在awt中可以使用,怎样解决呢?

以下是awt组件的截图

楼主如果只是问弹出菜单的话,参考一下下面:

import java.awt.event.*;
import javax.swing.*;

public class MenuTest
{
public static void main(String[] args)
{
MenuFrame frame = new MenuFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
}

/**
A frame with a sample menu bar.
*/
class MenuFrame extends JFrame
{
public MenuFrame()
{
setTitle("MenuTest");
setSize(DEFAULT_WIDTH, DEFAULT_HEIGHT);

Action cutAction = new TestAction("Cut");
Action copyAction = new TestAction("Copy");
Action pasteAction = new TestAction("Paste");

// demonstrate pop-ups

popup = new JPopupMenu();
popup.add(cutAction);
popup.add(copyAction);
popup.add(pasteAction);

JPanel panel = new JPanel();
add(panel);

JTextField field = new JTextField(20);
panel.add(field);

field.setComponentPopupMenu(popup);

}

public static final int DEFAULT_WIDTH = 300;
public static final int DEFAULT_HEIGHT = 200;

private JPopupMenu popup;
}

/**
A sample action that prints the action name to System.out
*/
class TestAction extends AbstractAction
{
public TestAction(String name) { super(name); }

public void actionPerformed(ActionEvent event)
{
System.out.println(getValue(Action.NAME) + " selected.");
}
}

弹右键菜单的ls都说过了
copy paste可以用Clipboard cb = java.awt.Toolkit.getDefaultToolkit().getSystemClipboard();
