Slider

Description

A slider bar that indicates a numeric value with a moveable position indicator.

All slider controls have a horizontal orientation. Calls the?onChange()?callback after the position of the indicator is changed or if its?notify()?method is called. Calls the?onChanging()?callback repeatedly while the user is moving the indicator. The?value?property contains the current position of the indicator within the range of?minvalue?to?maxvalue.
