    \class TQStyleFactory tqstylefactory.h
    \brief The TQStyleFactory class creates TQStyle objects.

    The style factory creates a TQStyle object for a given key with
    TQStyleFactory::create(key).

    The styles are either built-in or dynamically loaded from a style
    plugin (see \l TQStylePlugin).

    TQStyleFactory::keys() returns a list of valid keys, typically
    including "Windows", "Motif", "CDE", "MotifPlus", "Platinum",
    "SGI" and "Compact". Depending on the platform, "WindowsXP",
    "Aqua" or "Macintosh" may be available.
