Blackberry TrackBall and J2ME

3 replies [Last post]

I have my application working fine with the Blackberry 8700 and the
trackwheel, when the user presses the wheel it displays the menu commands
that fire the commandListener. The Blackberry 8800 uses the trackball and it
works for navigation it does not have any access to the menu commands. How
do I allow the user to select a Command using the trackball?

Thanks

Although I have not used the 8800, I have a 8100 (Pearl) and pressing the menu button next to trackball does display the menu (located in the upper right-hand corner).

I haven't tried a MIDlet on the 8800, the normal behavior for apps
though is for the user to press the menu button immediately to the left
of the trackball to display the menu, from which they can then select
the commands.

Hi,

I develop for the BlackBerry platform as well, so if you are talking about
net.rim.device.api.ui.Trackball, as far as I know it will be available only
if your class extends the net.rim.device.api.ui.UiApplication class.

If you are extending javax.microedition.midlet.MIDlet you cannot use it.

Well, hope I understood the problem right, otherwise please disregard my
comments :)

Br,
