SWT-ProgressBar Troubles on Pocket PC 2003 [message #443355]

Hello,

I have troubles implementing a progress bar which runs
in its own thread while waiting for database response.

The code I've used runs properly on SWT-Win32 whereas
the PPC implementation seems to be malfunctional when
used with multiple threads as it does not update the
progress indicator.

The code that I've used:

new Thread() {
public void run() {
for (final int[] i = new int[1]; i[0] <= maximum; i[0]++) {
try {Thread.sleep (10);} catch (Throwable th) {}
if (Display.getDefault().isDisposed()) return;
Display.getDefault().asyncExec(new Runnable() {
public void run() {
if (progressBar.isDisposed ()) return;
progressBar.setSelection(i[0]);
}
});
}
}
}.start();

Possibly anyone has experienced the same issue and can
provide me with a workaround?!

Thanks,

Ron

Doesn't the PPC using a different threading mechanism?
