java - 我需要将面板拆分两次，但我不知道该怎么做

Question

好的，我有一个尺寸为 1280x720 的框架。我需要将其拆分并在左侧创建 1000x720 的一侧，在右侧创建 280x720 的一侧。现在的面板是 1000x720，我需要再次将其分割为顶部 1000x520，底部 1000x200。我已经尝试了相当长一段时间了。如果您有任何可以帮助或分享您的经验的链接，那将会非常有帮助。所以它有 3 个区域:#1 1000x520。 #3 280x720 #2 1000x200

        secondSplit = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT,splitTableHand, chatPanel);

Answer 1

首先，您的程序出现编译错误。修复它们。您必须使用 JPanel 扩展 SplitTableHand。这样，您在 GamePanel 中的错误就得到了解决。

public class SplitTableHand extends JPanel

第二点是在 GamePanel 类构造函数中，您创建了 topPanel 并将其添加到框架中，而不是添加 secondSplit。

将GamePanel的构造函数更改为

public GamePanel() {
    secondSplit = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT,splitTableHand, chatPanel);

    secondSplit.setOneTouchExpandable(true);
    secondSplit.setDividerLocation(150);
    this.setSize(1280, 720);
    this.setResizable(false);
    this.setDefaultCloseOperation(EXIT_ON_CLOSE);
    //this.pack();
    this.setVisible( true );
    getContentPane().add( secondSplit );
}

在 SplitTableHand 类中，您还必须添加 splitPane。

在其构造函数中添加一条语句add(splitPane);
