Properties

Status

Gets the operational status of the color frame source watcher.

Methods

Start()	When this method is called, the color frame source watcher enumerates any existing color frame sources it has not already enumerated by firing a SourceAdded event for each one. An EnumerationCompleted event is fired when this enumeration is complete. The color frame source then starts watching for new color frame sources.
Stop()	When this method is called, the color frame source watcher stops looking for changes to the color frame source list. This operation is not immediate; the Stopped event will be triggered when the Stop operation is complete.

Events

EnumerationCompleted	Subscribes to the EnumerationCompleted event. This event is fired after the initial enumeration of known color frame sources is complete.
SourceAdded	Subscribes to the SourceAdded event.
SourceRemoved	Subscribes to the SourceRemoved event. This event is fired once for every color frame source that is removed.
Stopped	Subscribes to the Stopped event. This event is fired when the IPerceptionColorFrameSourceWatcher has stopped listening for changes to the list of color frame sources.
