Why doesn't paint

[Fernando hiar]

What is wrong with my code!?!?!??!? Why doesn´t paint?!?!?!

	protected void pintar(Graphics g) { 
			Graphics2D g2d = (Graphics2D) g;
 			 int x =50, y =50; 
 			 String s;
 			 //System.out.println("pWidth: " + pWidth);
 			for(int i = 0; i <= 20; i++) {
				if(x > pWidth - 100) {
					y = y + 100;
					x = 50;
					x1[i] = x;
					y1[i] = y;
				}		
				try {
					s = (String)ima.id.get(i); // nome2 is BufferedImage
					nome2 = ima.getImage(s, i); // get the image loaded
					int w =  nome2.getWidth(null);
					int h = nome2.getHeight(null);
					bi = new BufferedImage(w,h,BufferedImage.TYPE_INT_ARGB);
					g2d =  bi.createGraphics();
					g2d.drawImage(bi, x,y,this);
					g2d.dispose();
					x1[i] = x;	
					x = x + 100;
				}	
				catch(Exception e) {
				e.printStackTrace();
				}		
			}
 			
 		}

I´m using active rendering, thanks...

Something passes your method a Graphics object. You cast it to Graphics2D. So far so good.

Then you load an image from somewhere, somehow. Then you create a new Graphics2D object and draw the image on it. You never display this Graphics2D object to the user, and you never do anything with the Graphics object which was passed to the method.

In addition to what Paul said,

protected void pintar(Graphics g) 

Is any piece of your code, calling this method? If all it does is paint(!) why create a new method? The usual recommended way of custom painting is overriding the paintComponent method.
