the easing mode and value a given property of an object should have at a

<p>The mode specified is the easing mode used when going to from the previous
key to the specified key.</p>
<p>For instance, the code below:</p>
<div class="informalexample"><pre class="programlisting">
clutter_state_set (state, NULL, "hover",
button, "opacity", CLUTTER_LINEAR, 255,
button, "scale-x", CLUTTER_EASE_OUT_CUBIC, 1.2,

NULL);
</pre></div>
<p></p>
<p>will create a transition from any state (a <em class="parameter"><code>source_state_name</code></em>
or NULL is
treated as a wildcard) and a state named "hover"; the
<span class="emphasis"><em>button</em></span> object will have the <a class="link" href="ClutterActor.html#ClutterActor--opacity" title="The “opacity” property"><span class="type">“opacity”</span></a>
property animated to a value of 255 using <a class="link" href="ClutterTimeline.html#CLUTTER-LINEAR:CAPS"><code class="literal">CLUTTER_LINEAR</code></a> as the animation
mode, and the <a class="link" href="ClutterActor.html#ClutterActor--scale-x" title="The “scale-x” property"><span class="type">“scale-x”</span></a> and <a class="link" href="ClutterActor.html#ClutterActor--scale-y" title="The “scale-y” property"><span class="type">“scale-y”</span></a> properties
animated to a value of 1.2 using <a class="link" href="ClutterTimeline.html#CLUTTER-EASE-OUT-CUBIC:CAPS"><code class="literal">CLUTTER_EASE_OUT_CUBIC</code></a> as the animation
mode. To change the state (and start the transition) you can use the
<a class="link" href="ClutterState.html#clutter-state-set-state" title="clutter_state_set_state ()"><code class="function">clutter_state_set_state()</code></a> function:</p>
<div class="informalexample"><pre class="programlisting">
clutter_state_set_state (state, "hover");

<p></p>
<p>If a given object, state_name, property tuple already exist in the
<a class="link" href="ClutterState.html" title="ClutterState"><span class="type">ClutterState</span></a> instance, then the mode and value will be replaced with
the new specified values.</p>
<p>If a property name is prefixed with "delayed::" two additional
arguments per key are expected: a value relative to the full state time
to pause before transitioning and a similar value to pause after
transitioning, e.g.:</p>
<div class="informalexample"><pre class="programlisting">
clutter_state_set (state, "hover", "toggled",
button, "delayed::scale-x", CLUTTER_LINEAR, 1.0, 0.2, 0.2,

NULL);
</pre></div>
<p></p>
<p>will pause for 20% of the duration of the transition before animating,
and 20% of the duration after animating.</p>
