<p>Typedefed as <a class="el" href="classGtk_1_1TreeView.html#ac8c004cc10cc48e6e4ce8ccfe0e49279" title="A selection object for Gtk::TreeView.">Gtk::TreeView::Selection</a>. </p>
<p>This is a helper object to manage the selection for a <a class="el" href="classGtk_1_1TreeView.html" title="The TreeView widget displays the model (Gtk::TreeModel) data and allows the user...">Gtk::TreeView</a> widget.</p>
<p>It is automatically created when a new <a class="el" href="classGtk_1_1TreeView.html" title="The TreeView widget displays the model (Gtk::TreeModel) data and allows the user...">Gtk::TreeView</a> widget is created, and cannot exist independently of this widget. The primary reason this class exists is for cleanliness of code and API. That is, there is no conceptual reason all these methods could not be methods on the <a class="el" href="classGtk_1_1TreeView.html" title="The TreeView widget displays the model (Gtk::TreeModel) data and allows the user...">Gtk::TreeView</a> widget instead of a separate class.</p>
<p>The <a class="el" href="classGtk_1_1TreeSelection.html" title="Typedefed as Gtk::TreeView::Selection.">Gtk::TreeSelection</a> object can be obtained from a <a class="el" href="classGtk_1_1TreeView.html" title="The TreeView widget displays the model (Gtk::TreeModel) data and allows the user...">Gtk::TreeView</a> by calling <a class="el" href="classGtk_1_1TreeView.html#ae953e086ee80dbcd34e49dc55a600dcb" title="Gets the Gtk::TreeSelection associated with tree_view.">Gtk::TreeView::get_selection()</a>. It can be manipulated to check the selection status of the tree, as well as to 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>When monitoring the selection of a view, it's important to remember that the "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. </p>
