The ScrollBar XFCN implements scroll bar controls for HyperCard. ScrollBar() must be invoked from a button/field script and will take its size from the object. After the scroll bar value has been changed ScrollBar() will optionally paint an updated picture of the bar onto the card or background as appropriate. ScrollBar() will also optionally send its parent object a message while it is tracking the scroll bar thumb.

As well as ScrollBar this stack contains:
PopupField XCMD: This "pops" fields into windows which exist until a mouse click. It is being used to show you this. For more details see my stack popupfield-setcursor.
VolumeLevel XFCN: Allows you to read and alter the volume level. Comes from my talker stack.
StandardFile XFCN: Provides you with myriads of ways of calling the standard file package. See the standard-file stack.
ResHandle XFCN: Resource handling functions for HyperCard. The heart of the resource-library stack.
