Uhm, i think you'll have to show some more code. an IntRect isn't drawable, an sf::Shape is on the other hand. Create drawable rectangles using sf::Shape::Rectangle(xpos, ypos, xsize,ysize,color,outline,outlinecolor);

You want Sprite::SetSubRect() from the sounds of it.

Make an intrect then pass it to SetSubRect.

    sf::Event Event;
    sf::IntRect r1(400, 400, 800, 800);
    sf::Image test;
    test.LoadFromFile("background.png");
    sf::Sprite test2;
    test2.SetImage(test);

    test2.SetSubRect(r1);


    sf::RenderWindow Window(sf::VideoMode(800,600,32),"aaa");
    while(Window.IsOpened())
    {
            while(Window.GetEvent(Event))
            {
                //Close Window
                if(Event.Type == sf::Event::Closed)
                Window.Close();


            }
  //  Window.Clear(sf::Color( 125,125,125 ));
    Window.Draw(test2);
    Window.Display();
    }






    return 0;
}
