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 WINAPI AdjustWindowRectEx(
  _Inout_  LPRECT lpRect,
  _In_     DWORD dwStyle,
  _In_     BOOL bMenu,
  _In_     DWORD dwExStyle
);

Parameters

lpRect [in, out]

Type: LPRECT

A 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]

Type: DWORD

The window style of the window whose required size is to be calculated. Note that you cannot specify the WS_OVERLAPPED style.

bMenu [in]

Type: BOOL

Indicates whether the window has a menu.

dwExStyle [in]

Type: DWORD

The extended window style of the window whose required size is to be calculated.

Return value

Type:

Type: BOOL

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.
