我需要分裂我的面板2次，我不知道如何做到这一点

Question

好的，我有一个框架，尺寸:1280x720。我需要拆分它，创建左边的一边是1000x720，右边是280x720。现在的面板是1000x720，我需要再次拆分它，顶部为1000x520，底部为1000x200。我已经试了很长时间了。如果你有任何链接来帮助或分享你的经验，那将会很有帮助。所以它有3个区域:#1 1000x520。# 3 280 x720# 2 1000 x200型

    public GamePanel() {
        secondSplit = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT,splitTableHand, chatPanel);
        secondSplit.setOneTouchExpandable(false);
        secondSplit.setDividerLocation(1000);
        this.setSize(1280, 720);

Answer 1

首先你的程序给出了编译错误。修复它们。你必须用JPanel扩展SplitTableHand。有了这个，你的错误在GamePanel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。

修改GamePanel的构造函数为

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，您也必须添加splitPane。

在它的构造函数add(splitPane);中添加一条语句
