## Element Instantiation
See [`delite/Widget`](/delite/docs/master/Widget.md) for full details on how instantiation lifecycle is working.

### Programmatic Instantiation

require([
"delite/register",
"deliteful/Button"
], function (register, button) {
var b = new Button({label: "I am a Button"});
b.placeAt(document.body);
});
```
## Element Configuration
The following properties can be set on the widget to configure it:
* `label`: the label to display in the button;
* `iconClass`: DOM class to apply to a DOM node before the label in order to render an icon;
