WM_SIZE

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

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

Parameters

• fwSizeType
  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 SIZE_MAXIMIZED value applies.

• nWidth
  Value of the low-order word of lParam. Specifies the new width of the client area.

• nHeight
  Value of the high-order word of lParam. Specifies the new height of the client area.

Return Values

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.
