40 \class QStylePlugin-
41 \brief The QStylePlugin class provides an abstract base for custom QStyle plugins.-
42-
43 \ingroup plugins-
44 \inmodule QtWidgets-
45-
46 QStylePlugin is a simple plugin interface that makes it easy-
47 to create custom styles that can be loaded dynamically into-
48 applications using the QStyleFactory class.-
49-
50 Writing a style plugin is achieved by subclassing this base class,-
51 reimplementing the pure virtual create() function, and-
52 exporting the class using the Q_PLUGIN_METADATA() macro.-
53-
54 \snippet qstyleplugin/main.cpp 0-
55-
56 The json metadata file \c mystyleplugin.json for the plugin needs-
57 to contain information about the names of the styles the plugins-
58 supports as follows:-
59-
60 \quotefile qstyleplugin/mystyleplugin.json-
61-
62 See \l {How to Create Qt Plugins} for details.-

67/*!-
68 \fn QStyle *QStylePlugin::create(const QString& key)-
69-
70 Creates and returns a QStyle object for the given style \a key.-
71 If a plugin cannot create a style, it should return 0 instead.-
72-
73 The style key is usually the class name of the required-
74 style. Note that the keys are case insensitive. For example:-

83 moc generated code that exports the plugin, so there is no need for calling it-
84 explicitly.-
