Callback

#
object Callback { get; }
Gets an instance of an object used to perform callbacks to the widget from handler implementations
Remarks: The callback should implement the parent class' callback interface so that there only needs to be a single callback for the entire hierarchy. This should return a static instance to avoid having overhead for each instance of your widget.
Returns: The callback instance to use for this widget
