Summary

Optional delegate method for additional processing.

Syntax

C#
VB
C++
public event EventHandler<MedicalViewerCellMouseEventArgs> CellMouseClick 
  
Public Event CellMouseClick As EventHandler(Of MedicalViewerCellMouseEventArgs) 
             
            public: 
event EventHandler<MedicalViewerCellMouseEventArgs^>^ CellMouseClick 
             

Event Data

The event handler receives an argument of type MedicalViewerCellMouseEventArgs containing data related to this event. The following MedicalViewerCellMouseEventArgs properties provide information specific to this event.

PropertyDescription
Button (Inherited from System.Windows.Forms.MouseEventArgs)Gets which mouse button was pressed.
CellIndex Gets the value that indicates the index of the cell that received the mouse event. This value is only valid if the cell is add to the MedicalViewer.
Clicks (Inherited from System.Windows.Forms.MouseEventArgs)Gets the number of times the mouse button was pressed and released.
Delta (Inherited from System.Windows.Forms.MouseEventArgs)Gets a signed count of the number of detents the mouse wheel has rotated, multiplied by the WHEEL_DELTA constant. A detent is one notch of the mouse wheel.
ImageRectangle Gets the rectangle that represents the image rectangle of the cell or sub-cell.
Location (Inherited from System.Windows.Forms.MouseEventArgs)Gets the location of the mouse during the generating mouse event.
Rectangle Gets the rectangle that represents the painting area of the cell or sub-cell.
SubCellIndex Gets the value that indicates the index of the sub-cell that received the mouse event.
X (Inherited from System.Windows.Forms.MouseEventArgs)Gets the x-coordinate of the mouse during the generating mouse event.
Y (Inherited from System.Windows.Forms.MouseEventArgs)Gets the y-coordinate of the mouse during the generating mouse event.
