yes, but you trigger it, because the drawing and other visual functions are not called instantly, but on every timer tick, and the timer's speed is 24 ticks/sec by default. so at every tick spark askes every component if the visuals have changed, and if so, calls the redraw, and thats where it goes back to your code..
