java - 改进 JFrame 和 JPanel 之间的通信

Question

我正在开发一款小游戏，需要在主 JFrame 和名为 gamepan 的 JPanel 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，隐藏的单词和其他东西......

问题是，当用户找到隐藏的单词时，我需要告诉我的 JFrame 他这样做了，这样稍后就可以重新绘制 gamepan，创建一个新单词。 ...

我所做的是:我在我的游戏盘中添加了一个 boolean 值，它告诉我的单词是否被找到，并在我的游戏盘中添加了一个MouseListener gamepan，所以每次我移动鼠标时，JFrame 都会测试是否找到该单词 然后在我的 gamepan 中添加 setter ，如果找到隐藏单词，我可以使用 JFrame 再次初始化事物。

我发现添加 MouseListener 并不是非常有效，因为我必须移动鼠标才能进行更改，并且每次鼠标移动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？我还想知道我是否在 gamepan 中添加了 setter 来为新单词设置其变量。

这是我的代码

游戏盘代码

private JPanel leftPan = new JPanel();

Answer 1

您可以使用一些在找到单词时发生的自定义事件:

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

然后让您的 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，注册一些更新方法，以便在发生此类事件时在 JFrame 中调用:

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，如果您想传输用户刚刚找到的单词，则可以将 MyEventListener#wordFound 方法声明如下:

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

编辑:添加了与 ScorePanel 实例的一些交互，以回答评论中的其他问题:)
