Hi,
Just starting out with J9/SWT on a PocketPC and couldn't find the
answer to this.
I'm playing around with some screen layouts, so I'm starting and
stopping my application a lot. I'm using the Shell constructor
without any options, so I get the "Smart Minimize". I know I can stop
the application from Setting/Memory, but I also wanted the option to
exit from within the application. I added a Menu bar with an Exit
option, and the listener for this issues a System.exit(0).
But doing this doesn't appear to release the memory used by the
application. Should it.
I decided to ask this here, because I'm also running a J9 "console"
application, and that doesn't seem to have any problems freeing the
memory, which makes me think my question is SWT related.
Cheers,
Eddie

Hi Eddie,
Did you try to call your application with j9w ? If I'm not wrong, that's
the solution for this problem.

I use PocketPC also. When I wanted a clean exit in the early stages of
development I used SWT.CLOSE to give me an OK button rather that a smart
minimise. This should unload the app.
If that's no use then maybe you are shorting the logic that deals with
disposing the widgets in using System.exit(0) directly? I don't know,
I've never done that myself.
It's not something I've ever been too concerned about - the smart
minimise feature is the way PocketPC works. Users don't exit
applications, they just stay loaded. Some PDAs give you a task switcher
that unloads things.
