MediaStreamTrackEvent extension type
The MediaStreamTrackEvent
interface of the
Media Capture and Streams API
represents events which indicate that a
MediaStream has had tracks added to or removed from the stream through
calls to
Media Capture and Streams API
methods. These events are sent to the stream when these changes occur.
The events based on this interface are MediaStream/addtrack_event
and
MediaStream/removetrack_event
.

Methods
-
composedPath(
) → JSArray< EventTarget> -
The
composedPath()
method of the Event interface returns the event's path which is an array of the objects on which listeners will be invoked. This does not include nodes in shadow trees if the shadow root was created with its ShadowRoot.mode closed.inherited -
initEvent(
String type, [bool bubbles, bool cancelable]) → void -
The
Event.initEvent()
method is used to initialize the value of anevent
created using Document.createEvent.inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
preventDefault(
) → void -
The
preventDefault()
method of the Event interface tells the that if the event does not get explicitly handled, its default action should not be taken as it normally would be.inherited -
stopImmediatePropagation(
) → void -
The
stopImmediatePropagation()
method of the Event interface prevents other listeners of the same event from being called.inherited -
stopPropagation(
) → void -
The
stopPropagation()
method of the Event interface prevents further propagation of the current event in the capturing and bubbling phases. It does not, however, prevent any default behaviors from occurring; for instance, clicks on links are still processed. If you want to stop those behaviors, see the Event.preventDefault method. It also does not prevent propagation to other event-handlers of the current element. If you want to stop those, see Event.stopImmediatePropagation.inherited -
toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
