我有你在图片中看到的结构。

对于这两个面板,都使用了 GridBagLayout。问题是滚动窗格内的文本字段并不完全可见。父面板仅会拉伸以使按钮可见,但当滚动条出现时,它只会与文本字段重叠。有没有简单的解决方案来解决这个问题(不想处理设置自定义/首选/最小高度)?

面板结构:

好的,这是一个 SSCCE

public class Main {
JFrame frame;
private JPanel mainPanel;
private JButton button1;
private JButton button2;
private JTextField someTextTextField;


public static void main(String[] args) {
    Main main = new Main();
    main.show();
}

private void show() {
    frame = new JFrame("Frame");
    frame.setContentPane(mainPanel);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.pack();

    frame.setVisible(true);
}


{

    $$$setupUI$$$();
}

private void $$$setupUI$$$() {
    mainPanel = new JPanel();
    mainPanel.setLayout(new GridBagLayout());
    mainPanel.setPreferredSize(new Dimension(209, 30));
    final JPanel panel1 = new JPanel();
    panel1.setLayout(new GridBagLayout());
    GridBagConstraints gbc;
    gbc = new GridBagConstraints();
    gbc.gridx = 1;
    gbc.gridy = 0;
    gbc.weightx = 0.5;
    gbc.weighty = 1.0;
    gbc.fill = GridBagConstraints.BOTH;
    mainPanel.add(panel1, gbc);
    button1 = new JButton();
    button1.setText("Button");
    gbc = new GridBagConstraints();
    gbc.gridx = 0;
    gbc.gridy = 0;
    gbc.fill = GridBagConstraints.HORIZONTAL;
    panel1.add(button1, gbc);
    button2 = new JButton();
    button2.setText("Button");
    gbc = new GridBagConstraints();
    gbc.gridx = 1;
    gbc.gridy = 0;
    gbc.fill = GridBagConstraints.HORIZONTAL;
    panel1.add(button2, gbc);
    final JScrollPane scrollPane1 = new JScrollPane();
    scrollPane1.setAlignmentX(0.0f);
    gbc = new GridBagConstraints();
    gbc.gridx = 0;

    mainPanel.add(scrollPane1, gbc);
    someTextTextField = new JTextField();
    someTextTextField.setText("some text");
    scrollPane1.setViewportView(someTextTextField);
}

/**

public JComponent $$$getRootComponent$$$() {
    return mainPanel;
}

}

尝试使用 aJTextArea而不是 a JTextField。如果您不想设置自定义/首选/最小尺寸,您可以使用该JTextArea.setRows(int rows)方法。我希望这会有所帮助。
