See \l {How to Create Qt Plugins} for details. - - \sa QScriptEngine::importExtension(), {Creating QtScript Extensions} -*/ - -/*! - \fn 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. \c{com.mycompany.MyProduct}). - - \sa initialize() -*/ - -/*! - \fn void QScriptExtensionPlugin::initialize(const QString& key, QScriptEngine *engine) - - Initializes the extension specified by \a key in the given \a engine. - The key must come from the set of keys(). - - \sa keys() -*/ - -/*! - Constructs a script extension plugin with the given \a parent. - - Note that this constructor is invoked automatically by the - Q_EXPORT_PLUGIN2() macro, so there is no need for calling it - explicitly. -*/ -QScriptExtensionPlugin::QScriptExtensionPlugin(QObject *parent) - : QObject(parent) -{ -} - -/*! - 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. -*/ -QScriptExtensionPlugin::~QScriptExtensionPlugin() -{ -} - -/*! - - This function is provided for convenience when reimplementing - initialize(). It splits the given \a key on \c{'.'} (dot), and - ensures that there's a corresponding path of objects in the - environment of the given \a 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 \c{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. - - \sa initialize() -*/ -QScriptValue QScriptExtensionPlugin::setupPackage( - const QString &key, QScriptEngine *engine) const -{ - QStringList components = key.split(QLatin1Char('.')); - QScriptValue o = engine->globalObject(); - for (int i = 0; i < components.count(); ++i) { - QScriptValue oo = o.property(components.at(i)); - if (!oo.isValid()) { - oo = engine->newObject(); - o.setProperty(components.at(i), oo); - } - o = oo; - } - return o; -} - -QT_END_NAMESPACE - -#endif // QT_NO_SCRIPT |
