HIntergrund Draw:

public class BackgroundPanel extends JPanel{
    private Image img;
    
    public BackgroundPanel()
    {
        URL url = getClass().getResource("background.jpg");
        img = getToolkit().getImage(url);
    }

    protected void paintComponent(Graphics g)
    {
        // Draws the img to the BackgroundPanel.
        super.paintComponent(g);
        g.drawImage(img, 0, 0, this);        
    }

}

läuft ja ganz gut soweit nur das problem ist, wenn ich das starte dann sehe ich vorerst nur das bild. Wenn ich allerdings es minimiere oder INS rand ziehe kommt alles.

wenn ich paint() mache, geht alles den bach runter ...

bitte um hilfe..

Ich gehe davon aus, dass die auskommentierten Teile von Zeile 116 bis 121 eigentlich nicht auskommentiert sind?

Wenn ja:

// Draws the img to the BackgroundPanel.
super.paintComponent(g);
g.drawImage(img, 0, 0, this);

hier zeichnest du zuerst die Components im Panel und danach das Bild. Also überzeichnest du mit dem Bild die Components. Versuch mal, die beiden Zeilen zu vertauschen, dann sollte es gehen.

 

[JDE4D]

die sind extra auskommentiert, weil die XYLayout Klassen von Oracle sind und nicht an die JAR weiter gegeben werden.

Die Zeilen zu vertauschen bewirkt das die componente ganz weggemalt werden...;(

Hatte das problem letztens auch,
nach dem ich die größe des Panels auf die des Bildes gesetzt habe hats funktioniert, hier meine Lösung:

[Java]

import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Image;
import javax.swing.JPanel;


/**

* Class implements a JPanel with Background. Minimum size of the Panel is the Image size

*

*
*

*/

public class JPanelWithBackground extends JPanel

{

/**

*

*/

private static final long serialVersionUID = -3164458435320161617L;

/*

* internal holder of the background image

*/

transient private Image image;

/**

* Constructor

*

* @param image

* Image Instance for the background

*/

public JPanelWithBackground(final Image image)

{

super();
Dimension size = new Dimension(image.getWidth(null), image.getHeight(null));
this.image = image;

/*

* Important resize before paint to ensure that the image is paint correct

*/

setPreferredSize(size);
setMinimumSize(size);
setMaximumSize(size);
setSize(size);
}


public void setImage(final Image image)

{

Dimension size = new Dimension(image.getWidth(null), image.getHeight(null));
this.image = image;

/*

* Important resize before paint to ensure that the image is paint correct

*/

setPreferredSize(size);
setMinimumSize(size);
setMaximumSize(size);
setSize(size);
}

/**

* Overwritten Painting method

*/

@Override

public void paintComponent(final Graphics graphic)
{

super.paintComponent(graphic);
graphic.drawImage(image, 0, 0, null);

}

}
[/Java]

 

[JDE4D]

wo muss ich das einsetzen?

PS: Meins ist exakt so groß wie das Bild, nur hab ich es im Desginer gemacht..

 

[marcusvw]

Also ich würds so machen:
[Java]
public BackgroundPanel()
{
URL url = getClass().getResource("background.jpg");
img = getToolkit().getImage(url);
Dimension size = new Dimension(img.getWidth(null), img.getHeight(null));
setPreferredSize(size);
setMinimumSize(size);
setMaximumSize(size);
setSize(size);

}
[/Java]
