JFrame에서 배경 이미지를 가질 때 JButton을 왼쪽으로 이동

Question

저는 Java를 처음 사용하고 프로젝트에서 작업하기가 매우 쉽습니다. 내 메인 메뉴를 만들기위한 테스트로서, 나는 JFrame과 파워 랜저 사진을 실험 해왔다. 내 문제는 여러 번 시도해 보았고 내 창 왼쪽에 내 놀이 및 도움말 버튼을 가져 오는 데 많은 시간을 소비했기 때문입니다. 나는 4의 눈금을 만들고 빈 레이블을 넣으려고했지만 그냥 작동하지 않습니다. 이 내 코드입니다 :

package be.kdg.AngryTanksKlad; 

import java.awt.*; 
import java.awt.event.ActionEvent; 
import java.io.IOException; 
import java.net.URL; 
import javax.imageio.ImageIO; 
import javax.swing.*; 

public class Main { 
    public static void main(String[] args) throws IOException { 
     final Image image = ImageIO.read(new URL("http://www.modernmom.com/sites/default/files/images/Power%2BRangers%2BPowerRangersMMPR.jpg")); 
     final JFrame frame = new JFrame(); 
     frame.add(new ImagePanel(image)); 
     frame.setSize(800, 600); 
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     frame.setVisible(true); 
    } 
    } 




@SuppressWarnings("serial") 
class ImagePanel extends JPanel { 
    private Image image; 
    private boolean tile; 
    private JPanel menu = new JPanel(new FlowLayout(FlowLayout.LEFT)); 

    ImagePanel(Image image) { 
    this.image = image; 
    this.tile = false; 
    final JButton play = new JButton("PLAY"); 
    final JButton help = new JButton("HELP"); 
    final JLabel empty = new JLabel(); 
    } 

    menu.setLayout(new GridLayout(4,4)); 

    menu.add(empty); 
    menu.add(play); 
    menu.add(help); 
    add(menu,BorderLayout.CENTER); 
    menu.setOpaque(false); 

    setVisible(true); 
}; 

@Override 
public void paintComponent(Graphics g) { 
    super.paintComponent(g); 
    if (tile) { 
     int iw = image.getWidth(this); 
     int ih = image.getHeight(this); 
     if (iw > 0 && ih > 0) { 
      for (int x = 0; x < getWidth(); x += iw) { 
       for (int y = 0; y < getHeight(); y += ih) { 
        g.drawImage(image, x, y, iw, ih, this); 
       } 
      } 
     } 
    } else { 
     g.drawImage(image, 0, 0, getWidth(), getHeight(), this); 
    } 
    } 
}

"내 문제는 내가 너무 여러 번 시도하고 왼쪽으로 내 플레이와 내 도움 버튼을 얻으려고 노력에 많은 시간을 할애 한 것입니다 내 창의. "

1. 랩 또 다른 JPanel
2. 의 메뉴 리터를 설정 ayout 메인 ImagePanel ~ BorderLayout입니다.
3. 새로운 JPanel

   JPanel panel = new JPanel(); 
   panel.setOpaque(false); 
   panel.add(menu); 
   setLayout(new BorderLayout()); 
   add(panel, BorderLayout.WEST); 
   

---

에 ImagePanel

setOpaque(false)의 BorderLayout.WEST에 새 JPanel 잘 작동 추가
