我正在编写一个Shooter（FPS-第一人称射击游戏），并且在JFrame中使用OpenGl（jogl 1.0）。
我想向JFrame添加一个ActionListener：
public class Main extends JDialog {
private static ActionListener action;
private static JFrame framePhaseOne;
private static JFrame framePhaseTwo;
...
...
action = new ActionListener() // this is for PHASE 2
{
public void actionPerformed(ActionEvent ae)
{
if (userPoints.getGamePhase()) // if F2 was clicked
{
framePhaseTwo = new JFrame(WorldName2);
framePhaseTwo.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
framePhaseTwo.setLocationByPlatform(true);
framePhaseTwo.setLocation(FRAME_LOCATION_X, FRAME_LOCATION_Y);
Renderer_PhaseTwo myCanvas2 = new Renderer_PhaseTwo(userPoints);
final Animator animator2 = new Animator(myCanvas2);
framePhaseTwo.add(myCanvas2);
framePhaseTwo.setSize(FRAME_SIZE_X, FRAME_SIZE_Y);
framePhaseTwo.addWindowListener(new WindowAdapter()
{
@Override
public void windowClosing(WindowEvent e)
{
new Thread()
{
@Override
public void run()
{
animator2.stop();
System.exit(0);
}
}.start();
}
});
framePhaseTwo.setVisible(true);
animator2.start();
myCanvas2.requestFocus();
myCanvas2.setFocusable(true);
}
}
};
我想补充action到framePhaseOne，我怎么能做到这一点，而不使用的JPanel和按钮？

问候
您不能将添加ActionListener到中JFrame，它的功能不像按钮，因此没有动作侦听器。
您正在寻找的是MouseListener。它检测鼠标单击。您可能还对MouseMotionListener感兴趣，该类可为您提供有关鼠标移动的信息。
这是一个例子：
framePhaseOne.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e){
System.out.println("Mouse was clicked on my frame!");
}
};
MouseAdapter是实现MouseListener的抽象类。它使您不必实施MouseListener接口所需的所有方法。
编辑：
在下面的注释中与您交谈之后，您想要的是KeyListener。同样，出于与MouseAdapter相同的原因，我推荐KeyAdapter。这是一个例子：
framePhaseOne.addKeyListener(new KeyAdapter(){
public void keyTyped(KeyEvent e){
if(e.getKeyCode()==KeyEvent.VK_F2){
//close frame one.
}
}
});
如果您还希望它也关闭您的第一帧，也可以使用framePhaseTwo来执行此操作。
framePhaseTwo.addKeyListener(new KeyAdapter(){
public void keyTyped(KeyEvent e){
if(e.getKeyCode()==KeyEvent.VK_F2){
//close frame one
}
}
});
请注意，框架需要重点关注以接收关键事件。
