public: event EventHandler<MedicalViewerAnnotationClickedEventArgs^>^ AnnotationClicked |
The event handler receives an argument of type MedicalViewerAnnotationClickedEventArgs containing data related to this event. The following MedicalViewerAnnotationClickedEventArgs properties provide information specific to this event.
Property | Description |
---|---|
Button | (Read only) Gets an enumerated value that indicates which Mouse button was used to click on the annotation object. |
CellIndex | (Read only) Gets the value that indicates the index of the cell that has the annotation that was clicked. This value is only valid if the cell is add to the MedicalViewer. |
SubCellIndex | (Read only) Gets the value that indicates the index of the sub-cell that has the annotation that was clicked. |
X | (Read only) Gets the value that indicates the X position for the pointer. |
Y | (Read only) Gets the value that indicates the Y position for the pointer. |
