QAbstractSlider

Abstract class to add functionalities common to all slider based widgets.

*This class implements all methods, properties of Qt's QAbstractSlider class so that it can be inherited by all slider based widgets**

QAbstractSlider is an abstract class and hence no instances of the same should be created. It exists so that we can add similar functionalities to all slider widget's easily. If you wish to create a slider use QDial instead.

*QAbstractSlider is the base class for all slider widgets.**

QAbstractSlider will list all methods and properties that are common to all slider widgets in the NodeGui world.
