<p>For complex widgets with an arbitrary number of animatable regions, it is up to the implementation to come up with a way to uniquely identify each animatable region. Using pointers to internal objects is one way to achieve this.</p>
<p>The widget also needs to notify the style context about a state change for a given animatable region so the animation is triggered. <a class="el" href="classGtk_1_1StyleContext.html#a69828cfb2665f5a911f22d09224f86f5" title="Notifies a state change on context, so if the current style makes use of transition animations...">notify_state_change()</a> can take no region IDs, meaning that the whole widget area will be updated by the animation.</p>
