Event Data

The event handler receives an argument of type MedicalViewerDesignerCreatedEventArgs containing data related to this event. The following MedicalViewerDesignerCreatedEventArgs properties provide information specific to this event.

PropertyDescription
Container Gets the annotation container that contains the annotation object that is being created, clicked under the run time mode or edited.
Designer Gets the newly created designer.
Object Gets the object that is being created, clicked under the run time mode, or edited.
SubCellIndex Gets the sub-cell index of the cell that contains the container of the object that is being created, clicked under the run time mode, or edited.
Type Gets the type of the newly created designer.
Remarks

This delegate occurs when the user:

  • starts creating a new annotation object using the Medical Viewer actions. For more information, refer to AddAction.
  • starts editing an already created annotation object, by either moving, resizing or rotating it.
  • clicks an already created annotation object in the Run mode. To enter the run mode, refer to MedicalViewerSubCell.UserMode.
