CWnd::WindowFromPoint

  • 项目

staticCWnd*PASCALWindowFromPoint(POINTpoint**);**

Return Value

A pointer to the window object in which the point lies. It is NULL if no window exists at the given point. The returned pointer may be temporary and should not be stored for later use.

Parameters

point

Specifies a CPoint object or POINT data structure that defines the point to be checked.

Remarks

Retrieves the window that contains the specified point; point must specify the screen coordinates of a point on the screen.

WindowFromPoint does not retrieve a hidden or disabled window, even if the point is within the window. An application should use the ChildWindowFromPoint member function for a nonrestrictive search.
