UpdateThumb

blk2blue.jpg

The UpdateThumb method positions the scrollbar thumb and enables or disables the vertical scroll bar depending on the number of items in the browse list, the currently selected item, and the active step distribution method. See Control Templates–BrowseBox for more information on thumb behavior.

Implementation:

The AddSortOrder method sets the stepdistribution methods for the BrowseClass object.

Example:

IF FIELD() = ?MyBrowse            !focus on browse list

 IF EVENT() = EVENT:NewSelection  !if new selection

  IF MyBrowse.TakeNewSelection()  !BrowseClass object handles it

   MyBrowse.UdateThumb            !Reposition the thumb

  END    

 END

END
