<a name="GtkTreeSelection.description"></a><h2>Description</h2>
<p>The <a class="link" href="GtkTreeSelection.html" title="GtkTreeSelection"><span class="type">GtkTreeSelection</span></a> object is a helper object to manage the selection
for a <a class="link" href="GtkTreeView.html" title="GtkTreeView"><span class="type">GtkTreeView</span></a> widget. The <a class="link" href="GtkTreeSelection.html" title="GtkTreeSelection"><span class="type">GtkTreeSelection</span></a> object is
automatically created when a new <a class="link" href="GtkTreeView.html" title="GtkTreeView"><span class="type">GtkTreeView</span></a> widget is created, and
cannot exist independently of this widget. The primary reason the
<a class="link" href="GtkTreeSelection.html" title="GtkTreeSelection"><span class="type">GtkTreeSelection</span></a> 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 <a class="link" href="GtkTreeView.html" title="GtkTreeView"><span class="type">GtkTreeView</span></a> widget instead of a separate function.</p>
<p>The <a class="link" href="GtkTreeSelection.html" title="GtkTreeSelection"><span class="type">GtkTreeSelection</span></a> object is gotten from a <a class="link" href="GtkTreeView.html" title="GtkTreeView"><span class="type">GtkTreeView</span></a> by calling
<a class="link" href="GtkTreeView.html#gtk-tree-view-get-selection" title="gtk_tree_view_get_selection ()"><code class="function">gtk_tree_view_get_selection()</code></a>. 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.</p>
<p>One of the important things to remember when monitoring the selection of
a view is that the <a class="link" href="GtkTreeSelection.html#GtkTreeSelection-changed" title="The “changed” signal"><span class="type">“changed”</span></a> 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 <a class="link" href="GtkTreeSelection.html#GtkTreeSelection-changed" title="The “changed” signal"><span class="type">“changed”</span></a> signal
when nothing has happened (mostly as a result of programmers calling
select_row on an already selected row).</p>
