| 释义 | RealChildWindowFromPoint 语法： HWND RealChildWindowFromPoint( HWND hwndParent, POINT ptParentClientCoords ); RealChildWindowFromPoint功能 该RealChildWindowFromPoint句柄函数检索在指定点的子窗口。搜索是限于直接子窗口;孙子和更深的子窗口都不会搜索。 参数 hwndParent [in]句柄窗口的孩子要检索。 ptParentClientCoords [in]指定POINT结构，它定义了客户端坐标，检查了这一点。 返回值 返回值是一个句柄到子窗口中包含指定点。 备注 RealChildWindowFromPoint对待一个标准的控制HTTRANSPARENT来自不同地区的控制的其他地区，它返回的背后控制的透明部分的子窗口。相反，ChildWindowFromPoint对待一个控制HTTRANSPARENT地区的其他领域一样。例如，如果该点的一个GroupBox的透明面积，RealChildWindowFromPoint返回后面GroupBox的子窗口，而ChildWindowFromPoint返回GroupBox的。但是，这两个API返回一个静态的领域，尽管它也返回HTTRANSPARENT。 功能信息 最低DLL版本 user32.dll 在Winuser.h中HeaderDeclared，头文件：winuser.h import libraryUser32.lib 最低经营systemsWindows 98时，Windows NT 4.0 SP4中 参见 视窗概述，ChildWindowFromPoint，点 ＝＝英文原文＝＝RealChildWindowFromPoint Function The RealChildWindowFromPoint function retrieves a handle to the child window at the specified point. The search is restricted to immediate child windows; grandchildren and deeper descendant windows are not searched. Syntax HWND RealChildWindowFromPoint( HWND hwndParent, POINT ptParentClientCoords ); Parameters hwndParent [in] Handle to the window whose child is to be retrieved. ptParentClientCoords [in] Specifies a POINT structure that defines the client coordinates of the point to be checked. Return Value The return value is a handle to the child window that contains the specified point. Remarks RealChildWindowFromPoint treats HTTRANSPARENT areas of a standard control differently from other areas of the control; it returns the child window behind a transparent part of a control. In contrast, ChildWindowFromPoint treats HTTRANSPARENT areas of a control the same as other areas. For example, if the point is in a transparent area of a groupbox, RealChildWindowFromPoint returns the child window behind a groupbox, whereas ChildWindowFromPoint returns the groupbox. However, both APIs return a static field, even though it, too, returns HTTRANSPARENT.
