JFrame打开JApplet

Question

我正在用java编写一个程序，JFrame中的JButton将隐藏JFrame并运行JApplet

我做了一些类似这样的事情

OpenButton.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e){

                hide();
                JApplet startGame = new MainApplet();

                startGame.init();
                startGame.start();
        }
});

我做错了什么？谢谢

我认为您正在寻找的解决方案是为主逻辑和顶级容器JFrame和JApplet创建一个单独的类。

public class GamePanel extends JPanel { ... your game here ... }
public class GameApplet extends JApplet {  
   private final GamePanel game;
   public GameApplect(GamePanel gamePanel) {
      this.game = game;
      super.add(game);
   }

   public void init() {
      ... applet init ... 
      this.game.init();
   }

   public void start() {
      ... applet start ...
      this.game.start(); 
   }
}

public class GameWindow extends JFrame {  
   private final GamePanel game;
   public GameApplect(GamePanel gamePanel) {
      this.game = game;
      super.add(game);
   }

   public void init() {
      ... frame init ... 
      this.game.init();
   }

   public void start() {
      ... frame start ...
      this.game.start(); 
   }
}

然后，您可以启动游戏窗口，而不是GameApplet的按钮点击。如果您已经在小程序或窗口中运行，则不需要创建单独的GameApplet和GamePanel类。您只需将GamePanel添加到您想要的任何容器中。
