A QML engine uses QNetworkAccessManager for all network access. By implementing a factory, it is possible to provide the QML engine with custom QNetworkAccessManager instances with specialized caching, proxy and cookies support. To implement a factory, subclass QQmlNetworkAccessManagerFactory and implement the virtual create() method, then assign it to the relevant QML engine using QQmlEngine::setNetworkAccessManagerFactory(). Note the QML engine may create QNetworkAccessManager instances from multiple threads. Because of this, the implementation of the create() method must be \l{Reentrancy and Thread-Safety}{reentrant}. In addition, the developer should be careful if the signals of the object to be returned from create() are connected to the slots of an object that may be created in a different thread: \list \li The QML engine internally handles all requests, and cleans up any QNetworkReply objects it creates. Receiving the QNetworkAccessManager::finished() signal in another thread may not provide the receiver with a valid reply object if it has already been deleted. \li Authentication details provided to QNetworkAccessManager::authenticationRequired() must be provided immediately, so this signal cannot be connected as a Qt::QueuedConnection (or as the default Qt::AutoConnection from another thread). \endlist For more information about signals and threads, see \l {Threads and QObjects} and \l {Signals and Slots Across Threads}. The \l {Qt Quick 1} version of this class is named QDeclarativeNetworkAccessManagerFactory. \sa {qml/networkaccessmanagerfactory}{NetworkAccessManagerFactory example} */ /*! Destroys the factory. The default implementation does nothing. */ QQmlNetworkAccessManagerFactory::~QQmlNetworkAccessManagerFactory() { } /*! \fn QNetworkAccessManager *QQmlNetworkAccessManagerFactory::create(QObject *parent) Creates and returns a network access manager with the specified \a parent. This method must return a new QNetworkAccessManager instance each time it is called. Note: this method may be called by multiple threads, so ensure the implementation of this method is reentrant. */ QT_END_NAMESPACE
