QScriptExtensionPlugin::QScriptExtensionPlugin(QObject *parent = Q_NULLPTR)

Constructs a script extension plugin with the given parent.

Note that this constructor is invoked automatically by the Q_PLUGIN_METADATA() macro, so there is no need for calling it explicitly.

QScriptExtensionPlugin::~QScriptExtensionPlugin()

Destroys the script extension 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] void QScriptExtensionPlugin::initialize(const QString &key, QScriptEngine *engine)

Initializes the extension specified by key in the given engine. The key must come from the set of keys().

See also keys().

[pure virtual] QStringList QScriptExtensionPlugin::keys() const

Returns the list of keys this plugin supports.

These keys are usually the names of the "modules" or "packages" that are implemented in the plugin (e.g. com.mycompany.MyProduct).

See also initialize().

QScriptValue QScriptExtensionPlugin::setupPackage(const QString &key, QScriptEngine *engine) const

This function is provided for convenience when reimplementing initialize(). It splits the given key on '.' (dot), and ensures that there's a corresponding path of objects in the environment of the given engine, creating new objects to complete the path if necessary. E.g. if the key is "com.trolltech", after the call to setupPackage() the script expression com.trolltech will evaluate to an object. More specifically, the engine's Global Object will have a property called "com", which in turn has a property called "trolltech".

Use this function to avoid global namespace pollution when installing your extensions in the engine.
