如何在父面板展開或摺疊時將面板連接到它的父面板

Question

我是新來的鞦韆。我正在使用JFD構建面板，以便每當面板窗口展開或摺疊時，內部內容也應該保持連接到面板並相應地展開或摺疊。

我一直在IntelliJ上使用JFormDesigner插件來這樣做。請在附加圖像上找到面板的樹形視圖。

我的問題是我應該調查哪個面板的屬性？

也許我無法在詢問這個問題時給你全部細節，但我對所有問題都開放。

這裏是我的代碼：

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)); 

       //---- mTextField6 ---- 
       mTextField6.setName("textField6"); 
       mPanel1.add(mTextField6, CC.xy(5, 5)); 

       //---- mLabel9 ---- 
       mLabel9.setText("text"); 
       mLabel9.setName("label9"); 
       mPanel1.add(mLabel9, CC.xy(9, 5, CC.RIGHT, CC.DEFAULT)); 

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

       //---- mCheckBox1 ---- 
       mCheckBox1.setText("text"); 
       mCheckBox1.setName("checkBox1"); 
       mPanel1.add(mCheckBox1, CC.xy(17, 5, CC.RIGHT, CC.DEFAULT)); 

       //---- mLabel7 ---- 
       mLabel7.setText("text"); 
       mLabel7.setName("label7"); 
       mPanel1.add(mLabel7, CC.xy(1, 9, CC.RIGHT, CC.DEFAULT)); 

       //---- mTextField7 ---- 
       mTextField7.setName("textField7"); 
       mPanel1.add(mTextField7, CC.xy(5, 9));

       mPanel1.add(mTextField11, CC.xywh(13, 13, 5, 1)); 
      } 
      mSplitPane1.setTopComponent(mPanel1); 
     } 
     add(mSplitPane1, CC.xy(1, 1));

我不知道是否它會幫助你或沒有，因爲你沒有SSCCE連接，但我會改變你的佈局如下：

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

要：

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

另外：

 // 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"));
