    \class QStyleFactory

    \brief The QStyleFactory class creates QStyle objects.

    \ingroup appearance

    The QStyle class is an abstract base class that encapsulates the

    look and feel of a GUI. QStyleFactory creates a QStyle object

    using the create() function and a key identifying the style. The

    styles are either built-in or dynamically loaded from a style

    plugin (see QStylePlugin).

    The valid keys can be retrieved using the keys()

    function. Typically they include "windows", "motif", "cde",

    "plastique" and "cleanlooks".  Depending on the platform,

    "windowsxp", "windowsvista" and "macintosh" may be available.

    Note that keys are case insensitive.

    \sa QStyle

*/

/*!

    Creates and returns a QStyle object that matches the given \a key, or

    returns 0 if no matching style is found.

    Both built-in styles and styles from style plugins are queried for a

    matching style.

    \note The keys used are case insensitive.
