-  \brief An abstract base class for slider widgets
-
-  QwtAbstractSlider is a base class for
-  slider widgets. It handles mouse events
-  and updates the slider's value accordingly. Derived classes
-  only have to implement the getValue() and
-  getScrollMode() members, and should react to a
-  valueChange(), which normally requires repainting.
+  \brief An abstract base class for slider widgets with a scale
+
+  A slider widget displays a value according to a scale.
+  The class is designed as a common super class for widgets like 
+  QwtKnob, QwtDial and QwtSlider.
+
+  When the slider is nor readOnly() its value can be modified 
+  by keyboard, mouse and wheel inputs. 
+
+  The range of the slider is divided into a number of steps from
+  which the value increments according to user inputs depend. 
+  Only for linear scales the number of steps correspond with
+  a fixed step size.
