关于SetWindowPos函数的用法,该如何处理
关于SetWindowPos函数的用法
唉！外语学的不太好，CSDN上的解释看的不是太懂
还望那位大哥指点指点
不胜感激。。。。
------解决方案--------------------
CSDN上的解释?MSDN吧?
函数作用主要是设定窗口尺寸,MSDN还是要学会看的,最起码基本的要能看懂,不然挺麻烦的,把每个函数的格式都记下不太可能

Syntax
BOOL SetWindowPos( HWND hWnd,
HWND hWndInsertAfter,
int X,
int Y,
int cx,
int cy,
UINT uFlags
);
Parameters
hWnd
[in] Handle to the window.
hWndInsertAfter
[in] Handle to the window to precede the positioned window in the Z order. This parameter must be a window handle or one of the following values.
HWND_BOTTOM
Places the window at the bottom of the Z order. If the hWnd parameter identifies a topmost window, the window loses its topmost status and is placed at the bottom of all other windows.
HWND_NOTOPMOST
Places the window above all non-topmost windows (that is, behind all topmost windows). This flag has no effect if the window is already a non-topmost window.
HWND_TOP
Places the window at the top of the Z order.
HWND_TOPMOST
Places the window above all non-topmost windows. The window maintains its topmost position even when it is deactivated.
For more information about how this parameter is used, see the following Remarks section.
X
[in] Specifies the new position of the left side of the window, in client coordinates.
Y
[in] Specifies the new position of the top of the window, in client coordinates.
cx
[in] Specifies the new width of the window, in pixels.
cy
[in] Specifies the new height of the window, in pixels.
uFlags
[in] Specifies the window sizing and positioning flags. This parameter can be a combination of the following values.
SWP_ASYNCWINDOWPOS
If the calling thread and the thread that owns the window are attached to different input queues, the system posts the request to the thread that owns the window. This prevents the calling thread from blocking its execution while other threads process the request.
SWP_DEFERERASE
Prevents generation of the WM_SYNCPAINT message.
SWP_DRAWFRAME
Draws a frame (defined in the window 's class description) around the window.
SWP_FRAMECHANGED
Applies new frame styles set using the SetWindowLong function. Sends a WM_NCCALCSIZE message to the window, even if the window 's size is not being changed. If this flag is not specified, WM_NCCALCSIZE is sent only when the window 's size is being changed.
SWP_HIDEWINDOW
Hides the window.
SWP_NOACTIVATE
Does not activate the window. If this flag is not set, the window is activated and moved to the top of either the topmost or non-topmost group (depending on the setting of the hWndInsertAfter parameter).
SWP_NOCOPYBITS
Discards the entire contents of the client area. If this flag is not specified, the valid contents of the client area are saved and copied back into the client area after the window is sized or repositioned.
SWP_NOMOVE
Retains the current position (ignores X and Y parameters).
SWP_NOOWNERZORDER
Does not change the owner window 's position in the Z order.
SWP_NOREDRAW
Does not redraw changes. If this flag is set, no repainting of any kind occurs. This applies to the client area, the nonclient area (including the title bar and scroll bars), and any part of the parent window uncovered as a result of the window being moved. When this flag is set, the application must explicitly invalidate or redraw any parts of the window and parent window that need redrawing.
SWP_NOREPOSITION
Same as the SWP_NOOWNERZORDER flag.
SWP_NOSENDCHANGING
Prevents the window from receiving the WM_WINDOWPOSCHANGING message.
