<p><a class="link" href="ClutterPanAction.html" title="ClutterPanAction"><span class="type">ClutterPanAction</span></a> is a sub-class of <a class="link" href="ClutterGestureAction.html" title="ClutterGestureAction"><span class="type">ClutterGestureAction</span></a> that implements
the logic for recognizing pan gestures.</p>
<p>The simplest usage of <a class="link" href="ClutterPanAction.html" title="ClutterPanAction"><span class="type">ClutterPanAction</span></a> consists in adding it to
a <a class="link" href="ClutterActor.html" title="ClutterActor"><span class="type">ClutterActor</span></a> with a child and setting it as reactive; for instance,
the following code:</p>
<div class="informalexample"><pre class="programlisting">
  clutter_actor_add_action (actor, clutter_pan_action_new ());
  clutter_actor_set_reactive (actor, TRUE);
</pre></div>
<p></p>
<p>will automatically result in the actor children to be moved
when dragging.</p>
