QStylePlugin::​QStylePlugin(QObject * parent = 0)

Constructs a style plugin with the given parent.

Note that this constructor is invoked automatically by the moc generated code that exports the plugin, 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.

[pure virtual] QStyle * QStylePlugin::​create(const QString & key)

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. For example:

QStyle *MyStylePlugin::create(const QString &key)
{
    QString lcKey = key.toLower();
    if (lcKey == "rocket") {
        return new RocketStyle;
    } else if (lcKey == "starbuster") {
        return new StarBusterStyle;
    }
    return 0;
}
