Success! LWUIT on Blackberry

Posted by wsnyder6 on July 9, 2008 at 6:41 PM EDT

This will be short and sweet.

To work around a race condition (see this thread), LWUIT needs to run on a separate thread on the Blackberry. Taking this into effect, together with a modified LWUIT distribution (removing references to M3G helper classes and the 3D Transition classes), I've finally got the demo to work on a simulator.

Granted, this in the JDE, not NetBeans. I need to figure that out yet. In the JDE, make sure you have the modified LWUIT dist set up as a library type project, and then make your a LWUIT midlet project dependent on that library.

Oh yeah, since LWUIT really relies on the presence of soft keys, you may want to use the BlackBerry UiApplication class to catch key events and wheel events, then translate those to the corresponding UI action. But you can also keep the same q/w and o/p softkeys in place.

Proof that it works!

Hello,
You will need to make it yourself by removing the M3G dependent classes from the base LWUIT dist. (Unzip the LWUIT jar, delete the classes, and zip it back up).

by andyfei - 2008-07-23 12:37

Good, may I ask where/how to get the modified LWUIT distribution? Thanks.

by wsnyder6 - 2008-07-10 11:45

I haven't tried loading this demo on the actual device yet. I will update this entry when I do.

by jayaskre - 2008-07-10 11:16

That's great. How easy now is it to update a real blackberry with LWUIT?

by pjulien - 2008-07-10 09:10

Yes, this is what I saw, on a midlet, the UIApplication instance is not null.

by wsnyder6 - 2008-07-10 09:03

No, because you can use the default application instance. Though, be warned, I have read in the Blackberry dev forums that this is not officially supported.

UiApplication.getUiApplication().addTrackwheelListener(myTrackwheelListener);

by pjulien - 2008-07-10 08:49

That's interesting but if you do that won't your app become a non-midlet app not suitable for LWUIT?

by wsnyder6 - 2008-07-10 06:38

You need to catch Wheel-clicks with the Blackberry UiApplication class and translate them to LWUIT actions.

Haven't tried moving the wheel around yet since I've been working in the simulator.

by pjulien - 2008-07-10 06:33

Are you able to use the wheel to move around? Are you able to push the wheel button to trigger an action?
