public class ImageComp

extends GUIComponent

Demonstrates extending GUIComponent, draws a picture in the background. Here's the code

 public class ImageComp extends GUIComponent
 {
         private SDLSurface background;
 
         public ImageComp(String filename)
         {
                 background = SDLImage.createFromFile(filename);
         }
         public void paint(GUIGraphics g)
         {
 
                 //super.paint(g);
                 java.awt.Rectangle bounds = this.getBounds();
                 g.setColor(getBackground());
                 g.fill3DRect(bounds);
 
                 int w,h;
 
                 // take the smaller of the two dimensions
                 if ((w=background.m_Width)> bounds.width) w=bounds.width-6;
                 if ((h=background.m_Height)> bounds.height) h=bounds.height-6;
 
                 // Remember, for g, all coordinates are rleative to parent
                 SDLRect src = new SDLRect(0,0,w,h);
                 SDLRect dest = new SDLRect(bounds.x+3,bounds.y+3,bounds.width,bounds.height);
                 System.out.println("ImageComp blitting surface src, dest="+ src + " " +dest);
                 g.blitSurface(background,src,dest);	
 
         }
