Although you can use the VScrollBar control as a stand-alone control, you usually combine it as part of another group of components to provide scrolling functionality.
A ScrollBar control consist of four parts: two arrow buttons, a track, and a thumb. The position of the thumb and the display of the arrow buttons depend on the current state of the ScrollBar control. The ScrollBar control uses four parameters to calculate its display state:

The <mx:VScrollBar> tag inherits all the
tag attributes of its superclass, and adds the following tag attributes:
