Event<AnimationTrack> EventTrackRemoved#

The Event triggered when an animation track is removed. You can subscribe to events via Connect() and unsubscribe via Disconnect(). You can also use EventConnection and EventConnections classes for convenience (see examples below).
Notice
For more details see the Event Handling article.
The event handler signature is as follows: myhandler(AnimationTrack anim_track)

Usage Example

Source code (C#)
// implement the TrackRemoved event handler
void trackremoved_event_handler(AnimationTrack anim_track)
{
	Log.Message("\Handling TrackRemoved event\n");
}

//////////////////////////////////////////////////////////////////////////////
