<hr/><a name="details" id="details"></a><h2>Detailed Description</h2>
<p>Functions dealing with evas smart objects (instances). </p>
<p>Smart objects are groupings of primitive evas objects that behave as a cohesive group. For instance, a file manager icon may be a smart object composed of an image object, a text label and two rectangles that appear behind the image and text when the icon is selected. As a smart object, the normal evas api could be used on the icon object.</p>
