view pattern lock with given value?

[jserodio]

This is great!

So far this is working as supposed to. But once I've saved the text pattern, lets say: 1-2-5-8-9
How can I draw the pattern automatically without a mouse-click interaction?
Can't I just pass the value 1-2-5-8-9 and draw it somehow?

I'm using it to store it from the user, but now I want to represent what the user has stored to be it more readable.
