Guess who's back... back again...
I finally got it. In my example, one line was missing.
public class Layouttest {
public static void main(String[] args) {
Display d = new Display();
Shell s = new Shell(d);
Group g = new Group(s, SWT.BORDER);
g.setBounds(s.getClientArea());
g.setLayout(new FillLayout(SWT.VERTICAL));
Button b1 = new Button(g, SWT.PUSH);
Button b2 = new Button(g, SWT.PUSH);
Button b3 = new Button(g, SWT.PUSH);
/* here */ g.layout();
s.open();
while (!s.isDisposed()) {
if (!d.readAndDispatch()) {
d.sleep();
}
}
d.dispose();
}
}

Layout happes when you call layout() or when the size of a control has
changed. If you moved the line "g.setBounds(..." to be after you have
configured the layout and create the buttons, then when the size was
changed, the layout would be in place and layout would happen. The upshot
of this is you could remove the explicit call to layout().
