\class QStyleFactory
\brief The QStyleFactory class creates QStyle objects.
\ingroup appearance
\inmodule QtWidgets
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" and "fusion".
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.
