java - 改善JFrame和JPanel之间的通信

我正在开发一个小型游戏，该游戏需要主JFrame和称为JPanel的gamepan之间进行通信。

游戏要求用户通过单击包含字母的按钮来找到隐藏的单词。

我的JFrame包含gamepan，scorepan，menus和其他内容...

我的gamepan包含我的buttonsArrayListener，隐藏的单词和其他内容...

问题是，当用户找到隐藏的单词时，我需要告诉我JFrame他这样做了，以便稍后可以重新绘制gamepan，重新创建一个单词...。

我所做的是：我在boolean中添加了一个gamepan来告知是否找到了我的单词，并在MouseListener中添加了gamepan，因此每次我移动鼠标时，JFrame都会测试该单词找到与否
然后在我的gamepan中添加了setter，如果找到了隐藏的单词，我将在JFrame中使用它们来重新初始化事物。

我发现添加MouseListener并不是很有效，因为我必须移动鼠标来进行更改，并且每次鼠标移动时都会进行无用的处理...

我想知道是否有比添加MouseListener更好的解决方案？而且我还想知道我是否很好地向gamepan添加了setter来为新单词设置其变量。

这是我的代码

最佳答案

您可以使用一些自定义事件，当发现一个单词时会发生该事件：

public interface MyEventListener {
    public abstract void wordFound(/* any data you could use */);
}

然后使您的GamePan能够发出此类事件：

public class GamePan extends JPanel {
    private final List<MyEventListener> myEventListeners = new LinkedList<>();

    // Here, keep everything you already have

    public void addMyEventListener(final MyEventListener listener) {
        this.myEventListeners.add(listener);
    }

    private void notifyWordFound(/* any data you could use */) {
        for(final MyEventListener listener : this.myEventListeners) {
            listener.wordFound(/* any data you could use */)
        }
    }
}

找到单词后，只需调用GamePan#notifyWordFound。
然后，在发生此类事件时，在您的JFrame中注册一些要调用的更新方法：

public class MyJFrame extends JFrame {
    // Here, keep everything you already have

    public JFrame() {
        // Here, keep everything you already have

        // Let's assume your ScorePanel instance is here:
        final ScorePanel scorePanel = new ScorePanel();

        this.gamePan.addMyEventListener(new MyEventListener() {
            @Override
            public void wordFound(/* any data you could use */) {
                // Update your application using any data you can use :)
                scorePanel.wordFound(/* any data you could use */);
            }
        });
    }
}

在这里，我们只需调用ScorePanel#wordFound方法，以便可以更新ScorePanel。

不要忘记，您可以通过所有这些方法传输您感兴趣的任何数据。例如，如果要发送用户刚刚找到的单词，可以将MyEventListener#wordFound方法声明为：

public interface MyEventListener {
    public abstract void wordFound(final String word);
}

编辑：添加了与ScorePanel实例的一些交互，以在注释中回答您的其他问题:)
