InheritanceTimeSlider Inheritance spark.components.supportClasses.SkinnableComponent
Implements ITimeSlider

Since : ArcGIS API for Flex 2.0

The Time Slider component for one or more maps that have time-aware layers. You can use the TimeSlider by either setting the Map.TimeSlider property (on a map) or listen to the TimeSlider.timeExtentChange event.
