Method XbpScrollBar():setData()

Sets the current position of the scroll box.

:setData( [<nScrlPos>] ) --> lSuccess

<nScrlPos> is an optional numeric value specifying the new position of the scroll box. If no data code block is contained in the instance variable :dataLink, <nScrlPos> is required.

This method returns the value .T. (true) when the position could be set, otherwise .F. (false) is returned.

The :setData() method sets the position of the scroll box within the scroll bar. If a code block is contained in the instance variable :dataLink, it is executed without parameters and the return value of the code block determines the position of the scroll box. The code block in :dataLink is not executed if a value is explicitly specified for the <nScrlPos> parameter when the method :setData() is called.
