如何顯示使用JFormDesigner生成的JDialog

Question

我生成了一個具有JFormDesigner的JDialog，但我不知道如何顯示它。這裏是代碼：

public class FinishPopup extends JDialog { 
     public FinishPopup(Frame owner) { 
      super(owner); 
      initComponents(); 
     } 

    public FinishPopup(Dialog owner) { 
     super(owner); 
     initComponents(); 
    } 

    public void initComponents() { 
     dialogPane = new JPanel(); 
     contentPanel = new JPanel(); 
     label1 = new JLabel(); 
     label2 = new JLabel(); 
     buttonBar = new JPanel(); 
     okButton = new JButton(); 
     label3 = new JLabel(); 

     Container contentPane = getContentPane(); 
     contentPane.setLayout(new BorderLayout()); 

     { 

      { 

       label1.setText("Money: "); 
       label1.setFont(new Font("Tahoma", Font.PLAIN, 12)); 


       label2.setText("Time"); 
       label2.setFont(new Font("Tahoma", Font.PLAIN, 12)); 

       GroupLayout contentPanelLayout = new GroupLayout(contentPanel); 
       contentPanel.setLayout(contentPanelLayout); 
       contentPanelLayout.setHorizontalGroup(
        contentPanelLayout.createParallelGroup() 
         .addGroup(contentPanelLayout.createSequentialGroup() 
          .addContainerGap() 
          .addComponent(label2) 
          .addGap(90, 90, 90) 
          .addComponent(label1) 
          .addContainerGap(105, Short.MAX_VALUE)) 
       ); 
       contentPanelLayout.setVerticalGroup(
        contentPanelLayout.createParallelGroup() 
         .addGroup(contentPanelLayout.createSequentialGroup() 
          .addContainerGap(GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE) 
          .addGroup(contentPanelLayout.createParallelGroup(GroupLayout.Alignment.BASELINE) 
           .addComponent(label2) 
           .addComponent(label1)) 
          .addContainerGap()) 
       ); 
      } 
      dialogPane.add(contentPanel, BorderLayout.CENTER); 

      { 
       buttonBar.setBorder(new EmptyBorder(12, 0, 0, 0)); 
       buttonBar.setLayout(new GridBagLayout()); 
       ((GridBagLayout)buttonBar.getLayout()).columnWidths = new int[] {0, 80}; 
       ((GridBagLayout)buttonBar.getLayout()).columnWeights = new double[] {1.0, 0.0}; 

       okButton.setText("OK"); 
       buttonBar.add(okButton, new GridBagConstraints(1, 1, 1, 1, 0.0, 0.0, 
        GridBagConstraints.CENTER, GridBagConstraints.BOTH, 
        new Insets(0, 0, 0, 0), 0, 0)); 
      } 
      dialogPane.add(buttonBar, BorderLayout.SOUTH); 

      label3.setText("Finished"); 
      label3.setFont(new Font("Tahoma", Font.BOLD, 14)); 
      dialogPane.add(label3, BorderLayout.NORTH); 
     } 
     contentPane.add(dialogPane, BorderLayout.CENTER); 
     pack(); 
     setLocationRelativeTo(getOwner()); 
    } 

    private JPanel dialogPane; 
    private JPanel contentPanel; 
    private JLabel label1; 
    private JLabel label2; 
    private JPanel buttonBar; 
    private JButton okButton; 
    private JLabel label3; 
} 

如何創建並顯示它？謝謝。

Answer 1

您需要首先創建一個類的實例，然後調用setVisible使其可見

// owner is reference to the parent frame or dialog. May be null, but you'll 
// need to cast it 
FinishPopup popup = new FinishPopup(owner); 
popup.setVisible(true); 

您也可以找到有用的setLocationRelativeTo
