GtkList::scroll_vertical
void scroll_vertical(
GtkScrollType
scroll_type
, double position);
This method needs
set_focus_vadjustment() to be
called on the appropriate scrollbar from the
GtkList in order for it to work. It scrolls the
list to a predetermined position according to the
GtkScrollType setting and, if a selection has been
made and the list's selection mode allows it, will automatically select
the child nearest to the new scroll position.
The position parameter is only used where the
enumerated value is GTK_SCROLL_JUMP, when
0.0 sets the scroll to the topmost item and
1.0 to the final item. Values between
0.0 and 1.0 describe the
percentage of the distance scrolled, i.e. 0.5 would
set the scroll so that the last visible item is the one holding the
halfway position in the list.
Where any other GtkScrollType is set, the
position is required but is then ignored.
