simulator trackball is not scrolling properly


when i scroll my home page with simulator(i.e with help of mouse) , it scrolls very fast . i implemented trackball event(trackballroll() and navigationmovement()) but then also it is scrolling very fast. and the focus jumps over many icons.

So,please tell me that mouse scrolling on trackball of simulator is having a different behaiiour from track ball functioning ?

 And how i can i test the proper functioning of track ball roll ? 

And how can i restrict the trackball rolling to more than one amount,so that focus gets only on next item,and it doesnt jump over other ?


Thanks and Regards,


Thanks and Regards

Re: simulator trackball is not scrolling properly

You are able to scroll faster using a mouse when using the BlackBerry Simulator than a user could on an actual BlackBerry handheld.  You can also use the arrow keys on your keyboard to test scrolling.  These allow you to move one "position" at a time.
