docs: // EventConfigureNewFromEvent returns an EventConfigure from an Event.
  //
  // Using widget.Connect() for the
  // "configure-event" signal results in a *Event being passed as
  // the callback's second argument. The argument is actually a
  // *EventConfigure. EventConfigureNewFromEvent provides a means of creating
  // an EventConfigure from the Event.
