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一侧为1000x720，右侧为280x720。现在是1000x720的面板我需要将它再次拆分为顶部的1000x520和底部的1000x200。我已经尝试了很长一段时间。如果您有任何帮助或分享您的经验的链接，这将非常有用。所以它的3个方面：＃1 1000x520。＃3 280x720 ＃2 1000x200

    ChatPanel chatPanel = new ChatPanel();


    public GamePanel() {

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

        secondSplit.setOneTouchExpandable(false);
        secondSplit.setDividerLocation(1000);
        this.setSize(1280, 720);

首先，您的程序正在提供编译错误。修复它们。您必须使用SplitTableHand扩展JPanel。这样，GamePanel中的错误就会得到解决。

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课程中，您还必须添加splitPane。

在其构造函数add(splitPane);

中添加一条语句

我需要拆分我的面板2次，我不知道该怎么做
