  afx_msg void OnMButtonDblClk( UINT  nFlags, CPoint  point  );
 
  Parameter   Description
 
  <nFlags>    Indicates whether various virtual keys are down. This
              parameter can be any combination of the following values:
 
              Value        Description
 
              MK_CONTROL   Set if CONTROL key is down.
 
              MK_LBUTTON   Set if left mouse button is down.
 
              MK_MBUTTON   Set if middle mouse button is down.
 
              MK_RBUTTON   Set if right mouse button is down.
 
              MK_SHIFT     Set if SHIFT key is down.
 
  <point>     Specifies the x- and y-coordinate of the cursor. These
              coordinates are always relative to the upper-left corner of
              CWnd.
 
  Remarks
 
  Called when the user double-clicks the middle mouse button.
 
  Only windows that have the CS_DBLCLKS WNDCLASS style will receive
  OnMButtonDblClk calls. This is the default for all Microsoft Foundation
  Class windows. Windows generates a OnMButtonDblClk call when the user
  presses, releases, and then presses the middle mouse button again within
  the system's double-click time limit. Double-clicking the middle mouse
  button actually generates four events: ◄WM_MBUTTONDOWN► and
  ◄WM_MBUTTONUP► messages, the WM_MBUTTONDBLCLK call, and another
  WM_MBUTTONUP message.
 
  This message-handler member function calls the ◄Default► member
  function. Override this member function in your derived class to handle
  the ◄WM_MBUTTONDBLCLK► message.
