This sounds very simple and probably is but how do you manipulate the slider position of a QwtSlider for example to set a range of initial positions. If I call setNum it updates the label but not the slider position. My apologies if I am missing something really easy here.

Is it possible to disable a QwtSlider without greying out the associated scale. Or is it possible to stop the slider from being moved without disabling it.

Thanks again in advance.
