We have constructed a little widget which allows the user to input a

a link in Pocket IE, which in turn connects to our mini java HTTP server
running under J9, which triggers the creation of this widget. However, in
order to get the widget to show up, I have to do a Shell.open(); When this
is done, Pocket IE is closed. I've used RAPI debug to verify that Pocket IE
indeed gets instructions to unload.
I've tried this in several versions of SWT (2026, 2136, 3101, and more) and
got the same results. The source of Shell from version 2.0.2 shows the
source of open() as:
public void open () {
checkWidget ();
bringToTop ();
/*
* Feature on WinCE PPC. A new application becomes the
* foreground application only if it has at least one
* visible window before the event loop is started.
* The workaround is to explicitely force the shell to
* be the foreground window.
*/
if (OS.IsWinCE) OS.SetForegroundWindow (handle);
setVisible (true);
if (!restoreFocus ()) traverseGroup (true);
}
Is it possible the OS.SetForegroundWindow() is causing pocket IE to close
erroneously? I cannot find the source for the OS class.
Thanks,
Joe Larson

I'll drop a question on the ms.public.pocketpc.developer group and find out
if they have a clue if SetForegroundWindow ought to do this.
Meanwhile, nothing else I've tried, including setVisible(true), seems able
to cause the swt window to appear.

Good question. PIE is actually gone from the task list. The timeout
thought is interesting, I doubt it could be involved but I'll take a poke at
that possibility.
Thanks for the reply!
