Member variable XbpScrollBar():autoTrack Foundation

Automatically updates the position of the scroll box.

Attribute: EXPORTED
Data type: Logical (.T.)

The :autoTrack instance variable contains the default value .T. (true) by default. This causes the current position of the scroll box to be automatically updated. If :autoTrack is set to .F. (false), the position of the scroll box must be explicitly specified using the method :setData(). In this case, the first message parameter passed to the callback code block :scroll or the method :scroll() must be used to determine the current position.
