how to control trackwheel sensitivity in Blackberry

trackwheelRoll( int amount, int status, int time)

Is there a way to control the trackwheel sensitivity from this method?

Thanks.

If you're trying to lower it, you can set a lastMoveTime flag in your class. After that, in your trackwheelRoll() method you can compare the time to that and see if you should move. For example:

protected boolean trackwheelRoll(int amount, int status, int time) {
    if(time - lastMoveTime > someTimeThatYouDetermine) {
        lastMoveTime = time;
        return super.trackwheelRoll(amount, status, time);
    }
    return false;
}

You'll set someTimeThatYouDetermine to control how much lower the sensitivity is. What this does is essentially discard some of the motion so it feels slower to the user.

Alternatively, if you want to increase sensitivity, you can simply multiply amount by some number.
