<hr><a name="_details"></a><h2>Detailed Description</h2>
A GtkTreeSelection C++ wrapper class.
<p>
<a class="el" href="classGFC_1_1Gtk_1_1TreeSelection.html">TreeSelection</a> is a helper object that manages the selection for a <a class="el" href="classGFC_1_1Gtk_1_1TreeView.html">TreeView</a> widget. The <a class="el" href="classGFC_1_1Gtk_1_1TreeSelection.html">TreeSelection</a> object is automatically created when a new <a class="el" href="classGFC_1_1Gtk_1_1TreeView.html">TreeView</a> widget is created, and cannot exist independentally of this widget. The primary reason the <a class="el" href="classGFC_1_1Gtk_1_1TreeSelection.html">TreeSelection</a> object exists is for cleanliness of code and API. That is, there is no conceptual reason why all its methods could not be methods on the <a class="el" href="classGFC_1_1Gtk_1_1TreeView.html">TreeView</a> widget.<p>
The <a class="el" href="classGFC_1_1Gtk_1_1TreeSelection.html">TreeSelection</a> object is gotten from a <a class="el" href="classGFC_1_1Gtk_1_1TreeView.html">TreeView</a> by calling <a class="el" href="classGFC_1_1Gtk_1_1TreeView.html#z1010_3">Gtk::TreeView::get_selection()</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>
One of the important things to remember when monitoring the selection of a view is that the <em>changed</em> 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 <em>changed</em> signal when nothing has happened (mostly as a result of programmers calling select_row on an already selected row).
