.SS "void QwtSliderBase::setMass (double val)\fC [virtual]\fP"
.PP
Set the slider's mass for flywheel effect. 
.PP
If the slider's mass is greater then 0, it will continue to move after the mouse button has been released. Its speed decreases with time at a rate depending on the slider's mass. A large mass means that it will continue to move for a long time.

Derived widgets may overload this function to make it public.
