Integer
ScrollOnThumbTrackState
Added for new scroll bar support. Only support batch style
This determines if the scroll occurs when the thumb is dragged
When false, it scrolls when the thumb is released. Only set it to
false if the scroll takes a long time.
IntegerThumbScrollState
This determines if thumb should be sized proportionally to the scroll
area. When true it acts like a normal windows list. When false, you get
old vdf behavior where thumb is small and scroll moves up down one line at
a time
set(integer iNewTop integer iNewCurrent)
the DFBaseEntryList class has it's own special Set_Top_item message (as of 9.0) which does not
set current_item. When used for non-batch lists, we don't want the set_current_item and
that is why it was removed. This fixes a problem when scrolling down/up when the entire
grid is shifted horizontally to the right. When you scroll, the grid would shift to col 0.
However, with batch lists we want the normal set_top_item or we get other problems. So we
we modify the method here to make it do a normal top_item (ie. set current_item).
While this top_item addition was added in 9.0 for DataLists classes it was not added to PickList classes,
which is the other branch off of Widelist. Since Picklists are always non-batch, this setting of
current_item is required and was added as of 11.1
