Most convenient way from qDebug to log...

I need to add a persistent log to my app. My idea is to transform the qDebug calls:
qDebug << "blablablablablabla " << variable1 << "blablabla" << variable2;
logInformation() << "blablablablablabla " << variable1 << "blablabla" << variable2;
that should do this:
QTextSream textStream; textStream << "blablablablablabla " << variable1 << "blablabla" << variable2; qDebug << textStream.readAll(); m_myLog.logInformation(textStream.readAll());
Which is the most convenient way to do the transformation with the less effort, in your opinion?
I would have thought of doing a sort of subclassing of the QDebug class, going to redefine some methods / operators, to obtain the same form of call. I don't know if it's feasible, I'm still thinking about it.
You should install custom log handler instead: qInstallMessageHandler.
This gives you full control over all logs, without any need to change existing calls - you can still use qDebug(), qWarning() etc.
