<!-- ##### SECTION Title ##### -->
GtkList

<!-- ##### SECTION Short_Description ##### -->
Widget for packing a list of selectable items

<!-- ##### SECTION Long_Description ##### -->
<para>
The #GtkList widget is a container whose children are displayed
vertically in order, and can be selected.

The list has many selection modes, which are programmer selective and
depend on how many elements are able to be selected at the same time.
</para>
<para>
GtkList has been deprecated since GTK+ 2.0 and should not be used
in newly written code. Use #GtkTreeView instead.

</para>

@list: the list widget.

in #GTK_SELECTION_EXTENDED.
</para>

@list: the list widget.
@scroll_type: the direction and length.
@position: the position if @scroll_type is #GTK_SCROLL_JUMP.

Scrolls @list horizontaly. This supposes that the list is packed into a
scrolled window or something similar, and adjustments are well
set. Step and page increment are those from the horizontal adjustment
of @list. Backward means to the left, and forward to the
right. Out of bounds values are truncated.
@scroll_type may be any valid #GtkScrollType. If @scroll_type is
#GTK_SCROLL_NONE, nothing is done. If it's #GTK_SCROLL_JUMP, the list
scrolls to the ratio @position: 0 is full left, 1 is full right.
</para>

@list: the list widget.

Scrolls @list vertically. This supposes that the list is packed into a
scrolled window or something similar, and adjustments are well
set. Step and page increment are those from the vertical adjustment
of @list. Backward means up, and forward down. Out of bounds values are
truncated.
@scroll_type may be any valid #GtkScrollType. If @scroll_type is
#GTK_SCROLL_NONE, nothing is done. If it's #GTK_SCROLL_JUMP, the list
scrolls to the ratio @position: 0 is top, 1 is bottom.

<para>
Toggles the focus row. If the focus row is selected, it's
unselected. If the focus row is unselected, it's selected. If the

as the selection is always at the focus row.
</para>

@list: the list widget.


<!-- ##### FUNCTION gtk_list_toggle_row ##### -->

Toggles the child @item of list. If the selection mode of @list is
#GTK_SELECTION_BROWSE, the item is selected, and the others are

<!-- ##### FUNCTION gtk_list_undo_selection ##### -->

<!-- ##### FUNCTION gtk_list_end_drag_selection ##### -->
<para>
Stops the drag selection mode and ungrabs the pointer. This has no
effect if a drag selection is not active.
