SplitPane 垂直不起作用

Question

我一直在 java swing 中使用 jsplit pane，我正在尝试在一个主框架中设置水平和垂直拆分窗格，首先在左右面板上划分主框架，然后在右边panel to bottom and top panel.I 成功将主框架分成左右面板，但之后它不能很好地分为底部和顶部面板，它分裂了右侧面板，并且在它的右半部分分成底部和顶部..有人可以帮我解决这个问题吗？提前致谢
拆分窗格代码：

split = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, scroll, panel);
add(split, BorderLayout.CENTER);
split.setDividerLocation(250);
panel.setBackground(Color.RED);


JPanel gPanel=new JPanel();
gPanel.setMinimumSize(new Dimension(30,30));
JPanel dPanel=new JPanel();
dPanel.setMinimumSize(new Dimension(30,30));
split2=new JSplitPane(JSplitPane.VERTICAL_SPLIT,gPanel,dPanel);
panel.add(split2,BorderLayout.CENTER);
split2.setDividerLocation(250);
gPanel.setBackground(Color.BLUE.brighter());

Answer 1

如果我没理解错的话，那么你需要嵌套拆分窗格，所以代码应该是这样的：

JPanel top = new JPanel();
JPanel bottom = new JPanel();
JSplitPane right = new JSplitPane(JSplitPane.VERTICAL_SPLIT, top, bottom);
JPanel left = new JPanel();
JSplitPane horizontal = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, left, right);
frame.add(horizontal, BorderLayout.CENTER);

SplitPane 垂直不起作用
