Is there a way to stop the movement of the slider at a certain
position? I want the user to drag the thumb until it reaches a critial
value, say 70% of the whole distance. Then the user should be able to
move the mouse further but the slider should stop at 70%.

I don't think you can do event.doit = false on a SelectionListener for a
slider, but you could do this:

final slider = new Slider(...)...

slider.addSelectionListener(new SelectionListener() {
public void widgetDefaultSelected(SelectionEvent e) {}
public void widgetSelected(SelectionEvent e) {
if (slider.getSelection() >= 70)

So if the user drops the slider > 70, it jumps back to 70.. You still get a
bit of a "boing boing" effect as you can still drag to 100 and let go. But
the drop will still be on 70.

Hope that helps,
