Something like this?
Cursor cursor = new Cursor(shell.getDisplay(), SWT.CURSOR_WAIT);
shell.setCursor(cursor);
....
shell.setCursor(null);

Hi,
The runnable which is taken as argument is executed in the same thread,
that is in the GUI thread.
Below is a snippet:
import org.eclipse.swt.custom.BusyIndicator;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
/**
* @author Robert Bacs
*/
public class BusyIndicatorTest {
public static void main(String[] args) {
final Display display = new Display();
final Thread thread = Thread.currentThread();
final Shell shell = new Shell(display);
shell.setLayout(new FillLayout());
System.out.println("Thread1: " + Thread.currentThread());
shell.pack();
shell.open();
shell.layout();
BusyIndicator.showWhile(display, new Runnable(){
public void run() {
if (thread == Thread.currentThread()){
System.out.println("Same thread !!!");
}
}
});
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
}

Runnables are not new threads. They are simply packaged methods. They
give you an interface to call into them using the run method. They don't
have to be on a separate thread.
showWhile() simply calls your runnable.run(). It does not need another
thread.
