    90     \class QStyleFactory

    91     \brief The QStyleFactory class creates QStyle objects.

    92 

    93     \ingroup appearance

    94 

    95     The QStyle class is an abstract base class that encapsulates the

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

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

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

    99     plugin (see QStylePlugin).

   100 

   101     The valid keys can be retrieved using the keys()

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

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

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

   105     Note that keys are case insensitive.

   106 

   107     \sa QStyle

   109 

   110 /*!

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

   112     returns 0 if no matching style is found.

   113 

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

   115     matching style.

   116 

   117     \note The keys used are case insensitive.
