public class ImageProcessor extends JApplet { 



JPanel panel1,panel2,panel3,panel4,panel5; 
JTextField nameTxt,addTxt,phoneTxt,emailTxt; 
JButton capture,download,cancle,sendEmail; 
JLabel head,name,add,phone,email; 


//function to align components using gridBagLayOut.. 
    private GridBagConstraints getConstraints(int gridx, int gridy,int gridwidth, int gridheight, int anchor) 
    { 
     GridBagConstraints c =new GridBagConstraints(); 
     c.insets = new Insets(10,10,10,10); 
     c.ipadx = 0; 
     c.ipady = 0; 
     c.gridx = gridx; 
     c.gridy = gridy; 
     c.gridwidth = gridwidth; 
     c.gridheight = gridheight; 
     c.anchor = anchor; 
     return c; 
    } 
//ends here... 



public void init() { 


    panel1 = new JPanel(); 
    panel2 = new JPanel(); 
    panel3 = new JPanel(); 
    panel4 = new JPanel(); 
    panel5 = new JPanel(); 

    nameTxt = new JTextField(20); 
    addTxt = new JTextField(20); 
    phoneTxt = new JTextField(20); 
    emailTxt = new JTextField(20); 

    capture = new JButton("capture"); 
    download = new JButton("download"); 
    sendEmail = new JButton("sendEmail"); 

    head = new JLabel("BUSINESS CARD READER"); 
    name = new JLabel("NAME:"); 
    add = new JLabel("ADDRESS:"); 
    phone = new JLabel("PHONE:"); 
    email = new JLabel("EMAIL:"); 

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

    panel1.setLayout(new BorderLayout()); 



    panel2.setLayout(new GridBagLayout()); 
    panel2.add(head,getConstraints(0,0,1,1,GridBagConstraints.CENTER)); 

    panel3.setLayout(new FlowLayout()); 
    panel3.add(capture); 
    panel3.add(download); 
    panel3.add(sendEmail); 

    panel4.setLayout(new GridBagLayout()); 

    panel4.add(name,getConstraints(0,0,1,1,GridBagConstraints.CENTER)); 
    panel4.add(nameTxt,getConstraints(1,0,1,1,GridBagConstraints.CENTER)); 

    panel4.add(add,getConstraints(0,1,1,1,GridBagConstraints.CENTER)); 
    panel4.add(addTxt,getConstraints(1,1,1,1,GridBagConstraints.CENTER)); 

    panel4.add(phone,getConstraints(0,2,1,1,GridBagConstraints.CENTER)); 
    panel4.add(phoneTxt,getConstraints(1,2,1,1,GridBagConstraints.CENTER)); 

    panel4.add(email,getConstraints(0,3,1,1,GridBagConstraints.CENTER)); 
    panel4.add(emailTxt,getConstraints(1,3,1,1,GridBagConstraints.CENTER)); 


    panel1.add(panel2,BorderLayout.NORTH); 
    panel1.add(panel3,BorderLayout.SOUTH); 
    panel1.add(panel4,BorderLayout.WEST); 
    panel1.add(panel5,BorderLayout.EAST); 
    setSize(500,500); 
    myPane.add(panel1,BorderLayout.CENTER); 


} 
public void start(){ 
    this.setSize(800,500); 

} 

}

Answer 1

創建JLabel沒有文字（""），並使用setIcon設置圖像被顯示。

Here就是一個例子。

Answer 2

在JButton或JLabel將照片添加到您的panel5：

JButton buttonForPicture = new JButton(); 
buttonForPicture.setBorder(new EmptyBorder(0, 0, 0, 0)); 
buttonForPicture.setOpaque(false); 
buttonForPicture.setIcon(new ImageIcon(imageFilePath)); 
panel5.add(buttonForPicture);
