<!-- ##### SECTION Title ##### -->
GtkTreeSelection
<!-- ##### SECTION Short_Description ##### -->
The selection object for GtkTreeView
<!-- ##### SECTION Long_Description ##### -->
<para>
The #GtkTreeSelection object is a helper object to manage the selection
for a #GtkTreeView widget. The #GtkTreeSelection object is
automatically created when a new #GtkTreeView widget is created, and
cannot exist independentally of this widget. The primary reason the
#GtkTreeSelection objects exists is for cleanliness of code and API.
That is, there is no conceptual reason all these functions could not be
methods on the #GtkTreeView widget instead of a separate function.
</para>
<para>
The #GtkTreeSelection object is gotten from a #GtkTreeView by calling
gtk_tree_view_get_selection(). It can be manipulated to check the
selection status of the tree, as well as select and deselect individual
rows. Selection is done completely view side. As a result, multiple
views of the same model can have completely different selections.
Additionally, you cannot change the selection of a row on the model that
is not currently displayed by the view without expanding its parents
first.
</para>
<para>
One of the important things to remember when monitoring the selection of
a view is that the #GtkTreeSelection::changed signal is mostly a hint. That is, it may
only emit one signal when a range of rows is selected. Additionally, it
may on occasion emit a ::changed signal when nothing has happened
(mostly as a result of programmers calling select_row on an already
selected row).

<!-- ##### SIGNAL GtkTreeSelection::changed ##### -->

Emitted whenever the selection has (possibly) changed. Please note that
this signal is mostly a hint. It may only be emitted once when a range
of rows are selected, and it may occasionally be emitted when nothing
has happened.
</para>
@treeselection: the object which received the signal.
<!-- ##### USER_FUNCTION GtkTreeSelectionFunc ##### -->
<para>
A function used by gtk_tree_selection_set_select_function() to filter
whether or not a row may be selected. It is called whenever a row's
state might change. A return value of %TRUE indicates to @selection
that it is okay to change the selection.
