hi,
does anyone know how I can stop a progressbar created like this:
ProgressBar p = new ProgressBar(parent, SWT.INDETERMINATE);
now I'd like to stop it at some time. Just like setting
p.setRedraw(false), but actually this also prevents the bar from being
redrawn when it should (another window temporarily before progressbar)

setRedraw() is definitely not what you want.
It sounds like what you want is p.setEnabled(false), but that doesn't seem
to work (at least on linux/gtk2, the progressbar continues to update after
setEnabled(false) is called). Perhaps this is a bug, or maybe my
understanding of what setEnabled() does for a ProgressBar is off.
Could you live with p.setVisible(false), and just have the progressbar
disappear?

I just checked this out with a native GTK app, and the progress bar
doesn't seem to honor the gtk_widget_set_sensitive call, so
ProgressBar.setEnabled() can't work under GTK.
My suggestion would be to either use setVisible() or swap out the
SWT.INDETERMINATE progress bar for a standard progress bar when you want
to show that the process is complete. (that is, use the indeterminate one
while the process is proceeding, but when the process is complete, remove
the indeterminate one and add a determinate one with
setSelection(getMaximum()) or thereabouts.

OK, last time replying to this thread (for some reason it piqued my
interest).
Anyway, I don't think there's a good way to do exactly what you want, but
you might be able to use this to get close to the same effect:
import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.RowLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.ProgressBar;
import org.eclipse.swt.widgets.Shell;
public class ProgressBarTest {
public static void main(String[] args) {
final Display display = new Display();
final Shell shell = new Shell(display, SWT.APPLICATION_MODAL | SWT.DIALOG_TRIM);
final org.eclipse.swt.widgets.Composite comp = new org.eclipse.swt.widgets.Composite(shell, SWT.NONE);
final ProgressBar bar = new ProgressBar(comp, SWT.INDETERMINATE);
final ProgressBar barComplete = new ProgressBar(comp, SWT.SMOOTH);
barComplete.setMaximum(2);
bar.setSize(300, 20);
barComplete.setSize(300, 20);
shell.setLayout(new RowLayout());
shell.pack();
shell.open();
new Thread() {
public void run() {
try {sleep(5000);} catch (InterruptedException e) {}
display.syncExec(new Runnable() {
public void run() {
barComplete.setSelection(1);
barComplete.moveAbove(bar);
}
});
try {sleep(5000);} catch (InterruptedException e) {}
display.syncExec(new Runnable() {
public void run() {
barComplete.moveBelow(bar);
}
});
}
}.start();
while (!shell.isDisposed ()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}
}

not really, as I only have to stop the bar if the thing _fails_ and
therefore is not complete. But as I pointed out in my other posting I'll
try it with using a standard bar and simulating the INTDETERMINATE style
on my own
