Putting an image in a JFrame

Question

I'm trying to paint an image onto a JFrame. Im making a monopoly game and need to paint the board, and repaint it after every turn. I dont know how to put an image onto a JFrame and was wondering if anyone could give me a basic algorithm or code example of how to do this. Thanks.

Answer 1

Here is the basic algorithm to paint to a JFrame:
Don't do it!
Set the preferred size of a JPanel and add the JPanel to the JFrame. Paint to the JPanel by extending the paintComponent method. When you're ready to display, then remember to pack the JFrame and setVisible appropriately.
You can read about doing this in the Java Tutorial.
public void paintComponent(Graphics g){ //override in JPanel
  super.paintComponent(g);
  //do what ever you need to do here to draw your graphics.
}I prefer to do all of my drawing to a BufferedImage and then use drawImage to show the image (off screen rendering):
public void paintComponent(Graphics g){ //override in JPanel
  g.drawImage(myImage, 0, 0, this);
}
