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

Syntax

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

Parameters

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

    SIZE_MAXIMIZED

    The window has been maximized.

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.
