The _WidgetBase module may not provide all the widget functionality your application will need. The dijit package provides mixins, or JavaScript object extensions, for your widget. These mixins can provide HTML templates, event handling for clicks, touches, focus, and a lack thereof, for example.

require(["dojo/_base/declare", "dijit/_WidgetBase", "dijit/_TemplatedMixin"],
function (declare, _WidgetBase, _TemplatedMixin) {
