The 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 MoveWindow(
HWND hWnd,
int X,
int Y,
int nWidth,
int nHeight,
BOOL bRepaint
);
Parameters
- hWnd Handle to the window.
- X Specifies the new position of the left side of the window.
- Y Specifies the new position of the top of the window.
- nWidth Specifies the new width of the window.
- nHeight Specifies the new height of the window.
- bRepaint Specifies 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 ValueIf the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
RemarksIf 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
programming - windows - WM_WINDOWPOSCHANGING,
[programming:windows:WM_WINDOWPOSCHANGED,
programming:windows:WM_MOVE,
programming - windows - WM_SIZE, and
programming - windows - WM_NCCALCSIZE messages to the window.
