    <title>Description</title>

    <para>The <link
linkend="class-gtktreeselection"><classname>gtk.TreeSelection</classname></link>
object is a helper object to manage the selection for a <link
linkend="class-gtktreeview"><classname>gtk.TreeView</classname></link>
widget. The <link
linkend="class-gtktreeselection"><classname>gtk.TreeSelection</classname></link>
object is automatically created when a new <link
linkend="class-gtktreeview"><classname>gtk.TreeView</classname></link>
widget is created, and cannot exist independent of this widget. The primary
reason the <link
linkend="class-gtktreeselection"><classname>gtk.TreeSelection</classname></link>
object exists is for cleanliness of code and API. That is, there is no
conceptual reason all these functions could not be methods on the <link
linkend="class-gtktreeview"><classname>gtk.TreeView</classname></link>
widget instead of a separate function. The <link
linkend="class-gtktreeselection"><classname>gtk.TreeSelection</classname></link>
object is retrieved from a <link
linkend="class-gtktreeview"><classname>gtk.TreeView</classname></link> by
calling the <link
linkend="method-gtktreeview--get-selection"><methodname>gtk.TreeView.get_selection</methodname>()</link>
method. It can be manipulated to check the selection status of the tree, as
well as select and deselect individual rows. Selection is done completely on
the 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 "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 the <link
linkend="method-gtktreeselection--select-path"><methodname>select_path</methodname>()</link>
or <link
linkend="method-gtktreeselection--select-iter"><methodname>select_iter</methodname>()</link>
methods on an already selected row).</para>

      <para>The <methodname>set_selection_function</methodname>() method
sets the selection function to <parameter>func</parameter> (a function or
method). If the selection function is set, it is called before any node is
selected or unselected, giving some control over which nodes are selected.
The selection function should return <literal>True</literal> if the state of
the node may be toggled, and <literal>False</literal> if the state of the
node should be left unchanged. The signature of the selection function
callback is:</para>
