Syntax
C#
VB
C++
public void HandleMouseDown( 
   MedicalViewerActionType actionType, 
   Control control, 
   MouseEventArgs args, 
   int objectIndex 
) 
  
Public Sub HandleMouseDown( _ 
   ByVal actionType As MedicalViewerActionType, _ 
   ByVal control As Control, _ 
   ByVal args As MouseEventArgs, _ 
   ByVal objectIndex As Integer _ 
)  
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.
