Spinning wheel issues

I'm trying to make a game where a wheel spins. A real wheel like a tire.
I got it to spin using the AnimPlus library but it spins then stops then starts again. I'm looking for it to spin continuously until the player clicks a button, then it stops at whatever point in the spin it is.

Also I need some way to know what angle it stopped at.

I did look at using a canvas but I did not see any way to keep it going like in the AnimPlus library.

Anyone have any ideas or has already done this?

thanks,
