[news.eclipse.platform.swt] Re: scroll speed

["MateuY" <mateu.yabar@xxxxxxxxxx>]

Ok, I've found the solution:

scrolledComposite.addControlListener(new ControlAdapter() {
   public void controlResized(ControlEvent e) {
    Rectangle r = scrolledComposite.getClientArea();
    scrolledComposite.setMinSize(displayCompo.computeSize(r.width, 
SWT.DEFAULT));

//I've added this lines
    scrolledComposite.getVerticalBar().setPageIncrement(r.height);
    scrolledComposite.getVerticalBar().setIncrement(10);
   }
  });
