<nPos>
<nPos> is a numeric value specifying the first item visible in the list box. This value is the item's ordinal position in the list of the XbpListbox object.
Method XbpListBox():setTopItem() Foundation
Sets the first item visible at the top of the list box.
Syntax
:setTopItem( <nPos> ) --> lSuccess
Parameters
Return
This method returns the value .T. (true) when the first item visible in the list box could be set, otherwise it returns .F. (false).
Description
The :setTopItem() method allows the first item in the display window of the XbpListbox object to be defined. This is used to explicitly scroll the list to ensure the specified item is visible.
Note that the list box may not be able to scroll sufficiently to display the item at the top of the list. This is because scrolling is limited to the maximum scroll range and hence it is not possible to display the last item at the top, for example.
