<p>
<a href="AtkSelection.html" title="AtkSelection"><span class="type">AtkSelection</span></a> should be implemented by UI components with children which
are exposed by <span class="type">atk_object_ref_child</span> and <span class="type">atk_object_get_n_children</span>, if
the use of the parent UI component ordinarily involves selection of one
or more of the objects corresponding to those <a href="AtkObject.html" title="AtkObject"><span class="type">AtkObject</span></a> children - for
example, selectable lists.
</p>
<p>
Note that other types of "selection" (for instance text selection) are
accomplished a other ATK interfaces - <a href="AtkSelection.html" title="AtkSelection"><span class="type">AtkSelection</span></a> is limited to the
selection/deselection of children.
