ChildWindowFromPoint info  Overview  Group

The ChildWindowFromPoint function determines which, if any, of the child windows belonging to a parent window contains the specified point.

HWND ChildWindowFromPoint(

    HWND hWndParent,

// handle to parent window

    POINT Point 

// structure with point coordinates



Identifies the parent window.
Specifies a POINT structure that defines the client coordinates of the point to be checked.

Return Values

The return value is the handle of the child window that contains the point, even if the child window is hidden or disabled. If the point lies outside the parent window, the return value is NULL. If the point is within the parent window but not within any child window, the return value is the handle to the parent window.


Windows maintains an internal list, containing the handles of the child windows associated with a parent window. The order of the handles in the list depends on the Z order of the child windows. If more than one child window contains the specified point, Windows returns the handle of the first window in the list that contains the point.
