<p>
<a class="link" href="ClutterDeviceManager.html" title="ClutterDeviceManager"><span class="type">ClutterDeviceManager</span></a> is a singleton object, owned by Clutter, which
maintains the list of <a class="link" href="ClutterInputDevice.html" title="ClutterInputDevice"><span class="type">ClutterInputDevice</span></a>s.
</p>
<p>
Depending on the backend used by Clutter it is possible to use the
<a class="link" href="ClutterDeviceManager.html#ClutterDeviceManager-device-added" title='The "device-added" signal'><span class="type">"device-added"</span></a> and
<a class="link" href="ClutterDeviceManager.html#ClutterDeviceManager-device-removed" title='The "device-removed" signal'><span class="type">"device-removed"</span></a> to monitor addition and removal
of devices.
