Blackberry: trackwheel stop motion listener

Question

I'm implementing an app that has a MapField , which I am extending.

I'm using navigationMovement(int dx, int dy, int status, int time) to move around this map (besides touchEvent(TouchEvent event) which i dont have a problem with).

The problem is that I want to do something when the user stops moving using the trackwheel , but I can't find a listener for this like the TouchEvent.UP for example.

Does anyone have an idea of what I can use to detect this?

Thanks in advance!

I'm not (yet) that familiar with BlackBerry-programming, but I don't remember seeing a listener for that anywhere.

One way I could think of to accomplish this could be to create a TimerTask , and store a timestamp in some class-variable when the TrackWheel moves (when your navigationMovement is called). Then in the navigationMovement, set the timestamp when the movement occurred (from the time-parameter passed to the method), and start a TimerTask which would then check after a while if the timestamp is marked a certain amount of time back (the wheel has not moved since), and if so, you know the trackwheel has stopped.
