I initialized the first bricks position, then made two `for` loops inside of which I created a `GRect` object, set its color and added it to the window and also adjusted the brick's location for each row and column but no bricks appear at all.

I also tried using `drawRect()` but still no bricks appeared.
I don't know what the problem is; why aren't any bricks added although the ball and the paddle are just fine?
