  long WindowStyle
);

Return Values

Possible return values include the following:

Remarks

This method is a thin wrapper over the SetWindowLong function and must be treated with care. In particular, you should retrieve the current styles and then add or remove flags. With some exceptions, flags allowed by the Windows CreateWindow function are acceptable. However, do not use this method to change the window size, and do not use the following flags:

  • WS_DISABLED
  • WS_HSCROLL
  • WS_ICONIC
  • WS_MAXIMIZE
  • WS_MINIMIZE
  • WS_VSCROLL
