\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",
"plastique" and "cleanlooks". 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.
