81 \brief The QStyleFactory class creates QStyle objects. -

82 -

83 \ingroup appearance -

84 \inmodule QtWidgets -

85 -

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

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

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

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

90 plugin (see QStylePlugin). -

91 -

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

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

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

95 and "macintosh" may be available. -

96 Note that keys are case insensitive. -

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

106 matching style. -
