Leadtools.Medical3D Namespace > Medical3DControl Class : ObjectRotated Event



Occurs when the user rotates the object with the mouse using the RotateObject action.

Syntax

Visual Basic (Declaration) 
Public Event ObjectRotated As EventHandler(Of Medical3DObjectEventArgs)
Visual Basic (Usage)Copy Code
Dim instance As Medical3DControl
Dim handler As EventHandler(Of Medical3DObjectEventArgs)
 
AddHandler instance.ObjectRotated, handler
C# 
public event EventHandler<Medical3DObjectEventArgs> ObjectRotated
C++/CLI 
public:
event EventHandler<Medical3DObjectEventArgs^>^ ObjectRotated
