<p>This function should never be used by applications: it is meant
for integration with embedding toolkits, like clutter-gtk</p>
<p>Embedding toolkits that disable the event collection inside Clutter
need to use this function to update the state of input devices depending
on a <a class="link" href="clutter-Events.html#ClutterEvent" title="union ClutterEvent"><span class="type">ClutterEvent</span></a> that they are going to submit to the event handling code
in Clutter though <a class="link" href="clutter-General.html#clutter-do-event" title="clutter_do_event ()"><code class="function">clutter_do_event()</code></a>. Since the input devices hold the state
that is going to be used to fill in fields like the <a class="link" href="clutter-Events.html#ClutterButtonEvent" title="struct ClutterButtonEvent"><span class="type">ClutterButtonEvent</span></a>
click count, or to emit synthesized events like <a class="link" href="clutter-Events.html#CLUTTER-ENTER:CAPS"><code class="literal">CLUTTER_ENTER</code></a> and
<a class="link" href="clutter-Events.html#CLUTTER-LEAVE:CAPS"><code class="literal">CLUTTER_LEAVE</code></a>, it is necessary for embedding toolkits to also be
responsible of updating the input device state.</p>
<p>For instance, this might be the code to translate an embedding toolkit
native motion notification into a Clutter <a class="link" href="clutter-Events.html#ClutterMotionEvent" title="struct ClutterMotionEvent"><span class="type">ClutterMotionEvent</span></a> and ask
Clutter to process it:</p>
<div class="informalexample"><pre class="programlisting">
ClutterEvent c_event;
translate_native_event_to_clutter (native_event, &c_event);
clutter_do_event (&c_event);
</pre></div>
<p></p>
<p>Before letting <a class="link" href="clutter-General.html#clutter-do-event" title="clutter_do_event ()"><code class="function">clutter_do_event()</code></a> process the event, it is necessary to call
<a class="link" href="ClutterInputDevice.html#clutter-input-device-update-from-event" title="clutter_input_device_update_from_event ()"><code class="function">clutter_input_device_update_from_event()</code></a>:</p>
<div class="informalexample"><pre class="programlisting">
ClutterEvent c_event;
ClutterDeviceManager *manager;
ClutterInputDevice *device;
translate_native_event_to_clutter (native_event, &c_event);
/* get the device manager */
manager = clutter_device_manager_get_default ();
/* use the default Core Pointer that Clutter
* backends register by default
*/
device = clutter_device_manager_get_core_device (manager, %CLUTTER_POINTER_DEVICE);
/* update the state of the input device */
clutter_input_device_update_from_event (device, &c_event, FALSE);
clutter_do_event (&c_event);
