public delegate void SurfaceChangedDelegate(XR.WSA.SurfaceId surfaceId,
XR.WSA.SurfaceChange changeType,
Bounds bounds,
DateTime updateTime);
Parameters
| surfaceId | The ID of the surface that has changed. | |
| changeType | The type of change this event represents (Added, Updated, Removed). | |
| bounds | The bounds of the surface as reported by the device. | |
