This message is sent to a window after its size has changed.

WM_SIZE fwSizeType = wParam; 
    nWidth = LOWORD(lParam); 
    nHeight = HIWORD(lParam);

Parameters

  Specifies the type of resizing requested. It must be the following value.

  Value	Description
  SIZE_RESTORED	The window has been resized, but neither the SIZE_MINIMIZED nor the SIZE_MAXIMIZED value applies.
  SIZE_MINIMIZED	The window has been minimized.
  SIZE_MAXIMIZED	The window has been maximized.
  SIZE_MAXSHOW	The window has been maximized and is displayed.

Return Value

Remarks

If the SetScrollPos or MoveWindow function is called for a child window as a result of the WM_SIZE message, the bRedraw parameter should be nonzero to cause the window to be repainted.

Although the width and height of a window are 32-bit values, the nWidth and nHeight parameters of the WM_SIZE message contain only the low-order 16 bits.
