<p>To create the genlist:</p>
<ol><li>
-<p>The genlist is created using the <span style="font-family: Courier New,Courier,monospace">elm_genlist_add()</span> function. For the genlist to be displayed properly, genlist item classes have to be created and defined with the <span style="font-family: Courier New,Courier,monospace">elm_genlist_item_class_new()</span> function. The following code snippet demonstrates how to set the item class properties. A <span style="font-family: Courier New,Courier,monospace">text_get</span> and a <span style="font-family: Courier New,Courier,monospace">content_get</span> callback function are defined to create item text and layout creation.</p>
