77 \brief The QStyleFactory class creates QStyle objects. -

78 -

79 \ingroup appearance -

80 \inmodule QtWidgets -

81 -

82 The QStyle class is an abstract base class that encapsulates the -

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

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

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

86 plugin (see QStylePlugin). -

87 -

88 The valid keys can be retrieved using the keys() -

89 function. Typically they include "windows" and "fusion". -

90 Depending on the platform, "windowsxp", "windowsvista" -

91 and "macintosh" may be available. -

92 Note that keys are case insensitive. -

93 -

94 \sa QStyle -

95 */ -

96 -

97 /*! -

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

99 returns 0 if no matching style is found. -

100 -

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

102 matching style. -

103 -

104 \note The keys used are case insensitive. -
