CMouseEvent Class

class CMouseEvent: public CWinEventBase

This class encapsulates a Windows mouse event. The LONG parameter of the Windows message contains the point at which the mouse event occurred. The function  GetPoint decodes the LONG parameter and returns it as a POINT. The WORD parameter contains flags indicating if certain virtual keys are down. The  TestFlags method can be used to test the flags with the following masks -

MK_CONTROL Set if the CTRL key is down. MK_LBUTTON Set if the left mouse button is down. MK_MBUTTON Set if the middle mouse button is down. MK_RBUTTON Set if the right mouse button is down. MK_SHIFT Set if the SHIFT key is down.
