76 \brief The QStyleFactory class creates QStyle objects. -

77 -

78 \ingroup appearance -

79 \inmodule QtWidgets -

80 -

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

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

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

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

85 plugin (see QStylePlugin). -

86 -

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

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

89 Depending on the platform, "windowsxp", "windowsvista", "gtk" -

90 and "macintosh" may be available. -

91 Note that keys are case insensitive. -

92 -

93 \sa QStyle -

94 */ -

95 -

96 /*! -

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

98 returns 0 if no matching style is found. -

99 -

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

101 matching style. -
