)

'Declaration
 
Public Sub HandleMouseDown( _
   ByVal actionType As MedicalViewerActionType, _
   ByVal control As Control, _
   ByVal args As MouseEventArgs, _
   ByVal objectIndex As Integer _
)

'Usage
 
Dim instance As Medical3DContainer
Dim actionType As MedicalViewerActionType
Dim control As Control
Dim args As MouseEventArgs
Dim objectIndex As Integer
 
instance.HandleMouseDown(actionType, control, args, objectIndex)

public void HandleMouseDown( 
   MedicalViewerActionType actionType,
   Control control,
   MouseEventArgs args,
   int objectIndex
)

 function Leadtools.Medical3D.Medical3DContainer.HandleMouseDown( 
   actionType ,
   control ,
   args ,
   objectIndex 
)

public:
void HandleMouseDown( 
   MedicalViewerActionType actionType,
   Control^ control,
   MouseEventArgs^ args,
   int objectIndex
)

Parameters

actionType: Leadtools.MedicalViewer.MedicalViewerActionType that represents the action that You wants to perform.
control: The control where the objects are rendered.
args: System.Windows.Forms.MouseEventArgs that represents the arguments that are received through one of the mouse events. You must pass the mouse event arguments that were received from the various mouse events, such as MouseDown, MouseUp, MouseMove, etc.
objectIndex: A zero-based index of the object that will receive the effects of handling the mouse event through this method.

Remarks

This method will automatically handle complicated mouse tasks and will perform the preset the actions.
