(integer) May be used in conjunction with winclass or ctype to specify window-style flags. This is equivalent to the “dwStyle” parameter in the WIN32 API CreateWindowsEx() function (consult the Microsoft documentation for details). As with winclass, these flags are only practical if they affect the appearance or other characteristic of the control without changing the way it interacts with the application.
