Can you anyone please explain me the events like TrackBall Navigation and Track ball click? How to handle that event?

Please explain with code example.

Thanks in Advance.

If you want to click the trackball programmically then you can use this code:

EventInjector.invokeEvent(new EventInjector.TrackwheelEvent(EventInjector.TrackwheelEvent.THUMB_CLICK ,  0,TrackwheelListener.STATUS_NOT_FROM_KEYPAD));
EventInjector.invokeEvent(new EventInjector.TrackwheelEvent(EventInjector.TrackwheelEvent.THUMB_UNCLICK ,  0,TrackwheelListener.STATUS_NOT_FROM_KEYPAD));

Do you mean a programmically click of the trackball?  

[ravindrakamble]

Programatically click and navigate?
