The VRDisplayEvent constructor creates a VRDisplayEvent object instance.

Syntax

var myEventObject = new VRDisplayEvent(type, eventInitDict);

type

A DOMString describing the type of event object you want to create.

eventInitDict

A object contaning initialization options to use when creating the constructor. These are:

display: A property containing the VRDisplay the event is to be associated with.
reason: A property containing a string representing the human-readable reason why the event is to be fired (see VRDisplayEvent.reason).

var myEventObject = new VRDisplayEvent('custom', {
  display: vrDisplay,
  reason: 'Custom reason'
});
