Подробное описание
The QStylePlugin class provides an abstract base for custom QStyle plugins.
QStylePlugin is a simple plugin interface that makes it easy to create custom styles that can be loaded dynamically into applications using the QStyleFactory class.
Writing a style plugin is achieved by subclassing this base class, reimplementing the pure virtual keys() and create() functions, and exporting the class using the Q_EXPORT_PLUGIN2() macro. See How to Create Qt Plugins for details.
See also QStyleFactory and QStyle.
Описание функций-членов
QStylePlugin::QStylePlugin ( QObject * parent = 0 )
Constructs a style plugin with the given parent.
Note that this constructor is invoked automatically by the Q_EXPORT_PLUGIN2() macro, so there is no need for calling it explicitly.
QStylePlugin::~QStylePlugin ()
Destroys the style plugin.
Note that Qt destroys a plugin automatically when it is no longer used, so there is no need for calling the destructor explicitly.
QStyle * QStylePlugin::create ( const QString & key ) [pure virtual]
Creates and returns a QStyle object for the given style key. If a plugin cannot create a style, it should return 0 instead.
The style key is usually the class name of the required style. Note that the keys are case insensitive. Например:
QStringList MyStylePlugin::keys() const
{
return QStringList() << "Rocket" << "StarBuster";
}
QStyle *MyStylePlugin::create(const QString &key)
{
QString lcKey = key;
if (lcKey == "rocket") {
return new RocketStyle;
} else if (lcKey == "starbuster") {
return new StarBusterStyle;
}
return 0;
}

QStringList QStylePlugin::keys () const [pure virtual]
Returns the list of style keys this plugin supports.
These keys are usually the class names of the custom styles that are implemented in the plugin.
