For example:</p>\n\n<pre><code>drawComponent.surface.add({\n type: 'circle',\n fill: '#ffc',\n radius: 100,\n x: 100,\n y: 100\n});\n</code></pre>\n\n<p>The configuration object passed in the <code>add</code> method is the same as described in the <a href=\"#!/api/Ext.draw.Sprite\" rel=\"Ext.draw.Sprite\" class=\"docClass\">Ext.draw.Sprite</a>\nclass documentation.</p>\n\n<h1>Listeners</h1>\n\n<p>You can also add event listeners to the surface using the <code>Observable</code> listener syntax.
