How to dispose the Form object which is added to Display / Container ?

[neeraja.nokia]

We developed a simple mobile application using new version of LWUIT. Jar(LWUIT_20081222). Overall performance of application

is very slow, we took maximum care in designing application like using threads etc, now we doubt the reason for bad

performance is unable to dispose Forms (Form objects) which are created and no longer required, let us know how to dispose

forms added to Display, or give us know your valuable suggestion on improving application performance especially LWUIT based

application.

When you change your display from Form to something else. You can use first display.setCurrent(null) then if that Form object is not needed then you can make it null so it can be garbage collected.

Thank u for replying-----
But, the method display.setCurrent(<object>) didn't exists in LWUIT.
I am asking disposing behaviour of LWUIT form.
Pls, give me ur suggestion---------

There's no need to call setCurrent(), that's a J2ME API call on the Display. You just call show() on your form. The garbage collector should eventually dispose your form.

I haven't experienced LWUIT being slow. Try deploying one of the demo apps (JAR files) that's part of the download.

I did see some API call with a null parameter on the LWUIT forums, if you really want to try looking, that forum is below:
