Question

我是新手。我正在使用JFD构建一个面板，这样每当面板窗口展开或折叠时，内部内容也应该保持与面板的连接，并相应地展开或折叠。

我一直在IntelliJ上使用JFormDesigner插件来执行此操作。请在附加图像上找到面板的树形视图。

我的问题是我应该考虑哪个小组的属性？

在提出这个问题时，我可能无法向您提供全部细节，但我对所有问题持开放态度。

这是我的代码：

public class aa extends JPanel 
{
    public aa() 
    {
        initComponents();
    }

    private void createUIComponents() {
        // TODO: add custom component creation code here
    }

    private void initComponents() 
    {
        // JFormDesigner - Component initialization - DO NOT MODIFY  //GEN-BEGIN:initComponents
        DefaultComponentFactory compFactory = DefaultComponentFactory.getInstance();
        mSplitPane1 = new JSplitPane();
        mPanel1 = new JPanel();
        mSeparator1 = compFactory.createSeparator("text");
        mLabel6 = new JLabel();
        mTextField6 = new JTextField();
        mLabel9 = new JLabel();
        mTextField9 = new JTextField();
        mCheckBox1 = new JCheckBox();
        mLabel7 = new JLabel();
        mTextField7 = new JTextField();
        mLabel10 = new JLabel();
        mTextField10 = new JTextField();
        mLabel8 = new JLabel();
        mTextField8 = new JTextField();
        mLabel11 = new JLabel();
        mTextField11 = new JTextField();

        //======== this ========
        setName("this");
        setLayout(new FormLayout(
            "default:grow",
            "fill:default:grow"));

        //======== mSplitPane1 ========
        {
            mSplitPane1.setOrientation(JSplitPane.VERTICAL_SPLIT);
            mSplitPane1.setDividerLocation(230);
            mSplitPane1.setOpaque(false);
            mSplitPane1.setName("splitPane1");

            //======== mPanel1 ========
            {
                mPanel1.setName("panel1");
                mPanel1.setLayout(new FormLayout(
                    "100dlu, $lcgap, 20dlu, $lcgap, 90dlu, $lcgap, default, $lcgap, 136dlu, $lcgap, 26dlu, $lcgap, 107dlu, $lcgap, default, $lcgap, 40dlu",
                    "6*(default, $lgap), 14dlu"));

                //---- mSeparator1 ----
                mSeparator1.setName("separator1");
                mPanel1.add(mSeparator1, CC.xywh(1, 1, 17, 1));

                //---- mLabel6 ----
                mLabel6.setText("text");
                mLabel6.setName("label6");
                mPanel1.add(mLabel6, CC.xy(1, 5, CC.RIGHT, CC.DEFAULT));

                mTextField9.setName("textField9");
                mPanel1.add(mTextField9, CC.xy(13, 5));

我不确定它是否会对您有所帮助，因为您没有附加SSCCE，但我会更改您的布局如下：

    setLayout(new FormLayout(
        "default:grow",
        "fill:default:grow"));

要：

    setLayout(new FormLayout(
        "fill:default:grow", // row must fill all its content
        "fill:default:grow"));

此外：

        // change "default" -> to "glue". this allows to make an empty growing column
        // if you want to make your fields growing, you should make them "fill:default:grow"
        mPanel1.setLayout(new FormLayout(
                "100dlu, $lcgap, 20dlu, $lcgap, 90dlu, $lcgap, default, $lcgap, 136dlu, $lcgap, 26dlu, $lcgap, 107dlu, $lcgap, default, $lcgap, 40dlu",
                "6*(default, $lgap), 14dlu"));

要：

        mPanel1.setLayout(new FormLayout(
                "100dlu, $lcgap, 20dlu, $lcgap, 90dlu, $lcgap, glue, $lcgap, 136dlu, $lcgap, 26dlu, $lcgap, 107dlu, $lcgap, default, $lcgap, 40dlu",
                "6*(default, $lgap), 14dlu"));
