Question

我正在制定时间表预订应用程序，当我运行项目时它显示组件（总框架），但是我希望当按下按钮重新加载时，组件应该是吐出的。（两个框架，其中一个在其他之下）通过溢出）???

根据您的描述，我认为您需要在点击按钮时在框架中添加splitpane，或者您已经在框架中添加了splitpane，并且想要在单击按钮时添加面板。

对于第一个选项，您可以执行以下操作：

    final JFrame frame = new JFrame("Split test");
    frame.setSize(400, 400);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    final JPanel jPanel2 = new JPanel();
    JLabel jLabel = new JLabel("I am added by click on button");
    jPanel2.add(jLabel);

    final JPanel jPanel = new JPanel();
    JButton button = new JButton("Click me to add pane in split");
    jPanel.add(button);

    button.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent arg0) {
            JSplitPane pane = new JSplitPane(JSplitPane.VERTICAL_SPLIT);
            pane.add(jPanel);
            pane.add(jPanel2);
            pane.setDividerLocation(frame.getHeight()/2); // set Divider location.
            frame.remove(jPanel);
            frame.add(pane);
            frame.validate();
        }
    });

    frame.add(jPanel);
    frame.setVisible(true);

如果你迟到了，那就试试这个：

    final JFrame frame = new JFrame("Split test");
    frame.setSize(400, 400);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    final JSplitPane pane = new JSplitPane(JSplitPane.VERTICAL_SPLIT);
    frame.add(pane);

    pane.setEnabled(false); // stop user from clicking on divider of split pane.

    final JPanel jPanel2 = new JPanel();
    JLabel jLabel = new JLabel("I am added by click on button");
    jPanel2.add(jLabel);

    final JPanel jPanel = new JPanel();
    JButton button = new JButton("Click me to add pane in split");
    jPanel.add(button);
    pane.add(jPanel);

    button.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent arg0) {
            pane.add(jPanel2);
            pane.setDividerLocation(frame.getHeight()/2); // set Divider location.
            pane.setEnabled(true); // let user change divider location.
        }
    });

    frame.setVisible(true);

重新加载组件框架
