    JFrame frame = new JFrame("Tabbed Pane Sample");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    JLabel label = new JLabel("Label");

panel.setLayout( new GridLayout() );
    JLabel label = new JLabel("Label");
    label.setPreferredSize(new Dimension(1000, 1000));
    JScrollPane jScrollPane = new JScrollPane(panel);

    JButton jButton1 = new JButton("Hello");

   // jScrollPane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
    jScrollPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
    jScrollPane.setViewportBorder(new LineBorder(Color.RED));
   // jScrollPane.getViewport().add(panel);

    frame.add(jScrollPane, BorderLayout.NORTH);
    panel.add(jButton1);
     panel.add(jButton2);
    frame.setSize(400, 150);
    frame.setVisible(true);
  }
}

推荐答案

将按钮添加到具有适当布局(例如GridLayout或FlowLayout)的面板中.将面板添加到滚动窗格.

Add the buttons to a panel with suitable layout (e.g. GridLayout or FlowLayout). Add the panel to the scroll pane.
