| 释义 | AdjustWindowRectEx 语法： BOOL AdjustWindowRectEx( LPRECT lpRect, DWORD dwStyle, BOOL bMenu, DWORD dwExStyle ); AdjustWindowRectEx函数 该AdjustWindowRectEx函数计算窗口的矩形所需的大小，对客户所需的大小的矩形。矩形窗口然后可以传递给CreateWindowEx函数创建一个窗口的客户区域所需的大小。 参数 lpRect [中，out]指向一个矩形结构，它包含的坐标顶级所需的客户区左，右下角的角落。当函数返回时，结构包含的坐标顶级窗口的左侧和右下角的角落，以满足所需的客户区。 dwStyle [in]指定窗口，其所需的大小，计算窗口样式。请注意，您不能指定WS_OVERLAPPED风格。 bMenu [in]指定窗口是否有一个菜单。 dwExStyle [in]指定窗口，其所需的大小，计算扩展窗口风格。有关更多信息，请参阅CreateWindowEx。 返回值 如果函数成功，返回值为非零。 如果函数失败，返回值是零。为了获得更多错误信息，调用GetLastError。 备注 客户端矩形是最小的矩形完全包含客户端区。矩形窗口是最小的矩形完全包含的窗口，其中包括客户区和非工作区。 该AdjustWindowRectEx函数不添加额外的空间时，菜单栏换行到两个或更多的行。 该AdjustWindowRectEx函数不考虑WS_VSCROLL或WS_HSCROLL样式。为了说明滚动条，调用SM_CXVSCROLL或SM_CYHSCROLL GetSystemMetrics函数。 功能信息 最低DLL版本 user32.dll 在Winuser.h中HeaderDeclared，头文件：winuser.h import libraryUser32.lib 最低操作系统Windows 95，Windows NT 3.1 UnicodeImplemented为Unicode版本。 参见 视窗概述，CreateWindowEx，RECT ＝＝英文原文＝＝AdjustWindowRectEx Function The AdjustWindowRectEx function calculates the required size of the window rectangle, based on the desired size of the client rectangle. The window rectangle can then be passed to the CreateWindowEx function to create a window whose client area is the desired size. Syntax BOOL AdjustWindowRectEx( LPRECT lpRect, DWORD dwStyle, BOOL bMenu, DWORD dwExStyle ); Parameters lpRect [in, out] Pointer to a RECT structure that contains the coordinates of the top-left and bottom-right corners of the desired client area. When the function returns, the structure contains the coordinates of the top-left and bottom-right corners of the window to accommodate the desired client area. dwStyle [in] Specifies the window style of the window whose required size is to be calculated. Note that you cannot specify the WS_OVERLAPPED style. bMenu [in] Specifies whether the window has a menu. dwExStyle [in] Specifies the extended window style of the window whose required size is to be calculated. For more information, see CreateWindowEx. Return Value If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. To get extended error information, call GetLastError . Remarks A client rectangle is the smallest rectangle that completely encloses a client area. A window rectangle is the smallest rectangle that completely encloses the window, which includes the client area and the nonclient area. The AdjustWindowRectEx function does not add extra space when a menu bar wraps to two or more rows. The AdjustWindowRectEx function does not take the WS_VSCROLL or WS_HSCROLL styles into account. To account for the scroll bars, call the GetSystemMetrics function with SM_CXVSCROLL or SM_CYHSCROLL.
