How do you paint an Image over a Panel? I'm trying to display an image on a panel but the image is drawn behind the panel not in front of it. :mad:

Any idea's?

I am assuming that you are adding that Panel to a Frame and the image is being drawn on the Frame (behind the Panel), yeah?

Right, this is what I would do,

Create a new class that inherits from java.awt.Panel . Override it's paint method, with something like this

public void paint(Graphics g){
        Image img = Toolkit.getDefaultToolkit().getImage(file_string);        
        g.drawImage(img, 0, 0, this.getWidth(), this.getHeight(), this);
}

Then simply add this Panel to your Frame. The kewl thing about this is if, your Panel get's resized the image will scale accordingly.

or if you don't need a whole class for the panel, you can just get it's graphics context and draw to that, like this:

Panel p=new Panel();
Graphics g=p.getGraphics();
g.drawImage(....);

Panels can be a bit strange so I'm not 100% sure if this works, but it should.

Yes that would work alright.

Why do I always think that ppl will want to make several instance of something. Bad phobos, BAD!!

Neither of thos are working for me, but they look sound. I'll review my code and let you know.

thanks

try adding a Canvas to the panel and then draw to the canvas (the same way as above).
