Detailed Description

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 method, then assign it to the relevant QML engine using setNetworkAccessManagerFactory() .

Note the QML engine may create QNetworkAccessManager instances from multiple threads. Because of this, the implementation of the method must be reentrant . In addition, the developer should be careful if the signals of the object to be returned from are connected to the slots of an object that may be created in a different thread:

  • The QML engine internally handles all requests, and cleans up any QNetworkReply objects it creates. Receiving the signal in another thread may not provide the receiver with a valid reply object if it has already been deleted.

  • Authentication details provided to must be provided immediately, so this signal cannot be connected as a QueuedConnection (or as the default AutoConnection from another thread).

For more information about signals and threads, see Threads and QObjects and Signals and Slots Across Threads.
