Java設計一個UI

-2

我正在製作一個特定的用戶界面在java中（編程），但我無法實現我的目標用戶界面。我需要幫助來實現我的目標用戶界面。我甚至嘗試過SWT設計師，但我仍然沒有成功。提前致謝。Java設計一個UI

我的代碼：

public class Main{ 

    /** 
    * @param args 
    */ 

    static JTextArea lblOne = new JTextArea ("Enter Nb Of Rows"); 
    static JButton btn1 = new JButton("Generate Table"); 
    final static TextField tf1 = new TextField(); 

    static JFrame AFrame; 

    public static void main(String[] args) { 
     // TODO Auto-generated method stub 

      AFrame = new JFrame("Pascal's Table Generator"); 

      AFrame.setLayout(new BorderLayout()); 

      // Add a window listner for close button 
      AFrame.addWindowListener(new WindowAdapter() { 

       public void windowClosing(WindowEvent e) { 
        System.exit(0); 
       } 
      }); 


      tf1.setText(""); 



      //AFrame.add(lblOne); 
      //lblOne.setText("      \n      "); 

      //JTextArea textArea = new JTextArea(5, 5); 
      JScrollPane scrollableTextArea = new JScrollPane(lblOne); 

      scrollableTextArea.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS); 
      scrollableTextArea.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS); 





      AFrame.getContentPane().add(scrollableTextArea); 

     // AFrame.add(new JScrollPane(lblOne)); 
      AFrame.add(btn1); 
      AFrame.add(tf1); 
      AFrame.setSize(800, 800); 


      btn1.addActionListener(new ActionListener() { 

      @Override 
      public void actionPerformed(ActionEvent arg0) { 
       // TODO Auto-generated method stub 
       lblOne.setText(""); 

       genPyrN(Integer.parseInt(tf1.getText().toString())); 
      } 
     }); 


      //set the layout of the frame to FlowLayout 
      //and align the components to the center 
      AFrame.setLayout(new FlowLayout(FlowLayout.CENTER)); 
     AFrame.setVisible(true);
