images.ui.graphics3d.events.AnnotationEditedEventData Class

Namespace: images.ui.graphics3d.events
Superclasses: event.EventData

Event data is passed when annotation label is edited

Since R2024a

Description

The images.ui.graphics3d.events.AnnotationEditedEventData class is the class passed to listeners when you interactively edit the label of an annotation in a Viewer3D object. When the object triggers an event using the notify handle class method, MATLAB^® assigns values to the properties of an AnnotationMovedEventData object and passes that object to the listener callback function (the event handler).

The images.ui.graphics3d.events.AnnotationEditedEventData class is a handle class.

Examples

Access Event Data

This code defines a callback function that gets the event properties from the images.ui.graphics3d.events.AnnotationEditedEventData object passed to it when the event is triggered.

function myCallbk(s,evtData)
   eventSource = evtData.Source;
   eventName = evtData.EventName;
   eventAnnotation = evtData.Annotation;
   eventCurrLabel = evtData.Label;
   eventPrevLabel = evtData.PreviousLabel;
   ...
end
