Connect for "proxyAuthenticationRequired" requires for registration of the QNetworkProxy



  • I need handle the signal proxyAuthenticationRequired of QNetworkAccessManager and show dialog. I wrote

    @ QObject::connect(nam, SIGNAL(proxyAuthenticationRequired(QNetworkProxy,QAuthenticator*)),
    mainWin, SLOT(onProxyAuthenticationRequired(QNetworkProxy, QAuthenticator*)));@

    where mainWin is a class for main window. But in console i see follow messages

    @QObject::connect: Cannot queue arguments of type 'QNetworkProxy'
    (Make sure 'QNetworkProxy' is registered using qRegisterMetaType().)@

    I knew about typedef and qRegisterMetaType, but I thought that QNetworkProxy should already be registered.



  • And instead it's not. :-)
    What's the problem in doing that?



  • I would bet a penny that

    @
    #include <QNetworkProxy>
    // or
    #include <QNetworkAccessManager>
    @

    in the source file that establishes the connection will cure the error.
