The QQmlNetworkAccessManagerFactory class creates QNetworkAccessManager instances for a QML engine.
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 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:
The Qt Quick 1 version of this class is named QDeclarativeNetworkAccessManagerFactory.
See also Network Access Manager Factory Example.
Destroys the factory. The default implementation does nothing.
[pure virtual]QNetworkAccessManager *QQmlNetworkAccessManagerFactory::create(QObject *parent)
Creates and returns a network access manager with the specified 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.
