JPanelとGroupLayoutマネージャでJDialogをサイズ変更

Question

GroupLayoutマネージャを持つJPanelを1つ持つJDialogがあります。

を使って、JDialogを作成します：

DialogPanel rectangeDialog = new DialogPanel(clickedObject); 
rectangeDialog.addWindowListener(new WindowAdapter() { 
    @Override 
    public void windowLostFocus(WindowEvent e) { 
     MainFrame.closeDialog(rectangeDialog.getModul()); 
    } 

    @Override 
    public void windowClosing(WindowEvent e) { 
     MainFrame.closeDialog(rectangeDialog.getModul()); 
    } 
}); 

コンストラクタ（DialogPanelはJDialogのを拡張）：

private static final int DIALOG_HEIGHT = 550; 
private static final int DIALOG_WIDTH = 1050; 

private RectangleModul modul = new RectangleModul(); 
private static final ImageIcon deleteIcon = createImageIcon("../resource/images/delete.gif"); 

    //Label-а за пътя и подравняване вдясно 
    private JLabel idTxt = new JLabel(); 
    //Input полето за път на квадратчето 
    private JTextField id = new JTextField(JTextField.RIGHT); 
    //Label-а за пътя и подравняване вдясно 
    private JLabel pathTxt = new JLabel(); 
    //Input полето за път на квадратчето 
    private JTextField path = new JTextField(JTextField.LEFT); 
    //Label-а за ниво и подравняване вдясно 
    private JLabel levelTxt = new JLabel(); 
    //Input полето за ниво на квадратчето 
    private JTextField level = new JTextField(); 
    //Label-а за име на квадратчето 
    private JLabel appellationTxt = new JLabel(); 
    //Input полето за име на квадратчето 
    private JTextField appellation = new JTextField(); 
    //Полето съдържащо описанието на квадрадтчето 
    private JTextArea description = new JTextArea(); 
    //Таблицата с елемите с дежав 
    private JTable childrenTable; 
public DialogPanel(RectangleModul modul) { 
     super(null, java.awt.Dialog.ModalityType.TOOLKIT_MODAL); 

     setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE); 

     //data initialization... 

     createDialogContent(); 

    } 

、ダイアログのコンテンツを作成：

private void createDialogContent() { 
    JPanel panel = new JPanel(); 
    //Панелът, който съдържа елемните 
    panel.setSize(DIALOG_WIDTH + 10, DIALOG_HEIGHT + 10); 
    panel.setAutoscrolls(false); 
    panel.setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5)); 

    //Layout на групите в панела 
    GroupLayout layout = new GroupLayout(panel); 

    //Вклюване на задаването на разстояния между елементите 
    layout.setAutoCreateGaps(true); 
    layout.setAutoCreateContainerGaps(true); 
    panel.setLayout(layout); 

    //Area-та за описанието на квадратчето 
    Border insideDescriptionBorder = BorderFactory.createTitledBorder("Описание"); 
    //ScrollBar-ът да полето за описание на квадратчето 
    JScrollPane scrollArea = new JScrollPane(description); 
    scrollArea.getVerticalScrollBar().setUnitIncrement(16); 
    scrollArea.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS); 
    scrollArea.setBorder(insideDescriptionBorder); 

    JScrollPane childrenTableScrollPane = new JScrollPane(childrenTable); 
    childrenTableScrollPane.getVerticalScrollBar().setUnitIncrement(16); 
    childrenTableScrollPane.setMaximumSize(new Dimension(20, 100)); 
    childrenTableScrollPane.setMinimumSize(new Dimension(20, 100)); 
    childrenTableScrollPane.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS); 

    //Панелът, който съдържа бутоните на диалоговия прозорец 
    JPanel panelButtons = new JPanel(); 
    panelButtons.setMaximumSize(new Dimension(20, 100)); 

    //Бутонът за запазване 
    JButton saveBtn = new JButton("Запази"); 

    saveBtn.addActionListener((ActionEvent e) -> { 
     //... 
    }); 
    panelButtons.add(saveBtn); 

    //Бутонът за създаване на ново дете 
    JButton addChildBtn = new JButton("Ново дете"); 
    addChildBtn.addActionListener((ActionEvent e) -> { 
     RectangleModul newModul = new RectangleModul(modul.getLevel() + 1, "Нов елемент", "", modul, new ArrayList<>(), new Polygon()); 
     addChild(newModul); 

     DialogPanel newDialogPanel = new DialogPanel(newModul); 
     newDialogPanel.setDefaultCloseOperation(DialogPanel.DISPOSE_ON_CLOSE); 
     newDialogPanel.addWindowListener(new WindowAdapter() { 
      @Override 
      public void windowClosing(WindowEvent e) { 
       //... 
      } 
     }); 
     newDialogPanel.setVisible(true); 
     MainFrame.getOpenPanels().add(newDialogPanel); 
    }); 
    panelButtons.add(addChildBtn); 

    //Бутонът за изтриване на елемнта и неговите деца 
    JButton deleteBtn = new JButton(modul.getLevel() == 0 ? "Изчисти проект" : "Изтрий"); 
    deleteBtn.addActionListener((ActionEvent e) -> { 
     //... 
    }); 
    panelButtons.add(deleteBtn); 
    panelButtons.setLayout(new FlowLayout(FlowLayout.LEFT)); 
    panelButtons.setSize(310, 10); 

    layout.setHonorsVisibility(true);

ダイアログです： 私は、コードを次しています

幅を増やすとすべてが問題なく、コンポーネントは幅に合わせます。

しかし、私は幅コンポーネントを減少させたときにその幅を減少させないでください。私はスクロールバーを望んでいません。ダイアログウィンドウの幅にコンポーネントを合わせたい（以下は望ましくない結果で、最初の画像と同じでなければならない）。私にはわからない

Answer 1

この本当の答えですが、質問からsandpaperedするためのより良い答えです！

レイアウトマネージャを変更して問題を解決しました。 私はGroupLayoutと変更し、GridBagLayoutと変更しました。

GridBagLayout gridBagLayout = new GridBagLayout(); 
     panel.setLayout(gridBagLayout); 

     gridBagLayout.rowHeights = new int[]{40, 40, 190, 190, 50}; 
     gridBagLayout.columnWidths = new int[]{40, 50, 70, 70, 700, 70, 50}; 

     panel.add(idTxt, newComponent(0, 0, 1, 1)); 

     panel.add(id, newComponent(1, 0, 1, 1)); 

     panel.add(pathTxt, newComponent(2, 0, 1, 1)); 

     panel.add(path, newComponent(3, 0, 1, 1)); 

     panel.add(new JLabel(""), newComponent(4, 0, 1, 1)); 

     panel.add(levelTxt, newComponent(5, 0, 1, 1)); 

     panel.add(level, newComponent(6, 0, 1, 1)); 

     panel.add(appellationTxt, newComponent(0, 1, 1, 1)); 

     panel.add(appellation, newComponent(1, 1, 6, 1)); 

     panel.add(scrollAreaDesc, newComponent(0, 2, 7, 1)); 

     panel.add(childrenTableScrollPane, newComponent(0, 3, 7, 1)); 

     panel.add(panelButtons, newComponent(0, 4, 6, 1)); 

そしてnewComponent：ここ

は、新しいコードがある

private GridBagConstraints newComponent(int x, int y, int w, int h) { 
     GridBagConstraints c = new GridBagConstraints(); 
     c.fill = y != 2 && y != 3 ? GridBagConstraints.HORIZONTAL : GridBagConstraints.BOTH; 
     c.gridx = x; 
     c.gridy = y; 
     c.gridwidth = w; 
     c.gridheight = h; 
     if (y == 2 || y == 3) { 
      c.weighty = 1.0; 
     } 
     if (x <=4 && (x + w) >=4) { 
      c.weightx = 1.0; 
     } 
     return c; 
    }
