public class MedicalViewerCobbAngle

'Declaration Public Class MedicalViewerCobbAngle

'Usage Dim instance As MedicalViewerCobbAngle

public ref class MedicalViewerCobbAngle

Remarks

After creating this object, add it to the MedicalViewerSubCell.CobbAngles collection of the MedicalViewerBaseCell control.

The two lines must be from the same container.

If any line got removed from the container, this class will be removed from MedicalViewerSubCell.CobbAngles as well.
