Image de Fond JFrame Fermé

Question

Bonjour, 


pour ajouter une image de fond à ma classe JFrame j'ai trouver en cherchant au net ce code:
 
package packTest;

import java.awt.*;

import javax.swing.JButton;
import javax.swing.JPanel;

import com.sun.media.sound.Toolkit;

public class ImagePanel extends JPanel {
	
	public Image image;
	BorderLayout bl1= new BorderLayout();
	
	public ImagePanel(){
		
		image=java.awt.Toolkit.getDefaultToolkit().getImage("Hydrangeas.jpg");
		
		try
	    {
	      jbInit();
	    }
	    catch(Exception e)
	    {
	      e.printStackTrace();
	    }
		
	}
	
	public void paintComponent(Graphics g)
	   {
	     super.paintComponent(g);
	 
	     int imageWight = image.getWidth(this);
	     int imageHeight = image.getHeight(this);
	 
	     g.drawImage (image, 0, 0, null);
	     repaint();
	   }

	private void jbInit() throws Exception
	  {
	    this.setLayout(bl1);
	  }
}

Mais je veux l'intégrer dans ma classe JFrame et je ne sais pas comment.
voilà ma classe:

package packTest;

import java.awt.BorderLayout;
import java.awt.EventQueue;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;

public class TestImage extends JFrame {

	private JPanel contentPane;

	/**
	 * Launch the application.
	 */
	public static void main(String[] args) {
		EventQueue.invokeLater(new Runnable() {
			public void run() {
				try {
					TestImage frame = new TestImage();
					frame.setVisible(true);
				} catch (Exception e) {
					e.printStackTrace();
				}
			}
		});
	}

	/**
	 * Create the frame.
	 */
	public TestImage() {
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setBounds(100, 100, 450, 300);
		contentPane = new JPanel();
		contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
		setContentPane(contentPane);
		contentPane.setLayout(null);
	}

}

Voici comment tu pourrais faire :

package packTest;

import java.awt.Container;
import java.awt.Graphics;
import java.awt.Image;

public class BackgroundContainer extends Container
{
    private static final long serialVersionUID = 1;

    private final Image img;
    private final int width;
    private final int height;

    public BackgroundContainer(Image background)
    {
        img = background;
        width = img.getWidth(this);
        height = img.getHeight(this);
    }

    @Override
    public void paint(Graphics g)
    {
        super.paint(g);
        g.drawImage(img, 0, 0, width, height, this);
        super.paintComponents(g);
    }
}
package packTest;

import javax.swing.ImageIcon;
import javax.swing.JFrame; 

public class TestImage extends JFrame
{
    private static final long serialVersionUID = 1;

    private final static ImageIcon background = new ImageIcon("Hydrangeas.jpg");

    public TestImage()
    {
        setContentPane(new BackgroundContainer(background.getImage()));
        setBounds(100, 100, 450, 300);
        setLayout(null);

        // Ajout des composants de la fenêtre

        setVisible(true);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }

    public static void main(String[] args)
    { 
        new TestImage(); 
    }
}
