Ok thank you very much I'll try with that.
But I have some design doubts, I'd like to keep the algorithm (for
example bfs) as clean as possible, being independent from the drawing
methods.
And how could I make it step through algorithms without having a more
complicated code? Maybe using threads?

Thanks
