Summary

The MedicalViewerDrawingAnnotationsEventArgs class provides data for the MedicalViewerBaseCell.StartDrawingAnnotation event.

Syntax

C++/CLI

public class MedicalViewerDrawingAnnotationsEventArgs : EventArgs

            public ref class MedicalViewerDrawingAnnotationsEventArgs : public System.EventArgs

Remarks

This class is sent by the event MedicalViewerBaseCell.StartDrawingAnnotation. The event MedicalViewerBaseCell.StartDrawingAnnotation is fired right before drawing the annotation object using the Medical Viewer actions. For more information on the action, refer to AddAction.

The event MedicalViewerBaseCell.StartDrawingAnnotation is used to set any default annotation value.
