CameraZoomed Event

Example 





Occurs when the user zooms the camera with the mouse using the ZoomCamera action.
Syntax
public event EventHandler<Medical3DCameraEventArgs> CameraZoomed
'Declaration
 
Public Event CameraZoomed As EventHandler(Of Medical3DCameraEventArgs)
'Usage
 
Dim instance As Medical3DControl
Dim handler As EventHandler(Of Medical3DCameraEventArgs)
 
AddHandler instance.CameraZoomed, handler
public event EventHandler<Medical3DCameraEventArgs> CameraZoomed
add_CameraZoomed(function(sender, e))
remove_CameraZoomed(function(sender, e))

public:
event EventHandler<Medical3DCameraEventArgs^>^ CameraZoomed
Remarks
To enable the Action, use the Leadtools.MedicalViewer.MedicalViewerBaseCell.AddAction(Leadtools.MedicalViewer.MedicalViewerActionType) method to add the action to the Medical3DControl. Then use the Leadtools.MedicalViewer.MedicalViewerBaseCell.SetAction(Leadtools.MedicalViewer.MedicalViewerActionType,Leadtools.MedicalViewer.MedicalViewerMouseButtons,Leadtools.MedicalViewer.MedicalViewerActionFlags) to associate the action with a mouse button.
