MoveWindow function

Changes the position and dimensions of the specified window. For a top-level window, the position and dimensions are relative to the upper-left corner of the screen. For a child window, they are relative to the upper-left corner of the parent window's client area.

Syntax


BOOL WINAPI MoveWindow(
  _In_  HWND hWnd,
  _In_  int X,
  _In_  int Y,
  _In_  int nWidth,
  _In_  int nHeight,
  _In_  BOOL bRepaint
);

Parameters

hWnd [in]

Type: HWND

A handle to the window.

X [in]

Type: int

The new position of the left side of the window.

Y [in]

Type: int

The new position of the top of the window.

nWidth [in]

Type: int

The new width of the window.

nHeight [in]

Type: int

The new height of the window.

bRepaint [in]

Type: BOOL

Indicates whether the window is to be repainted. If this parameter is TRUE, the window receives a message. If the parameter is FALSE, 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 moving a child window.

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

If the bRepaint parameter is TRUE, the system sends the WM_PAINT message to the window procedure immediately after moving the window (that is, the MoveWindow function calls the UpdateWindow function). If bRepaint is FALSE, the application must explicitly invalidate or redraw any parts of the window and parent window that need redrawing.

MoveWindow sends the WM_WINDOWPOSCHANGING, WM_WINDOWPOSCHANGED, WM_MOVE, WM_SIZE, and WM_NCCALCSIZE messages to the window.
