Qt DBus Monitor Method Calls

[geocool]

I'm using QtQuick 2 And C++ in my application.(Qt 5.2)
I would like to monitor dbus method calls and I don't know if this is possible from Qt DBus Library.
For example I would like monitor Notify method of org.freedesktop.Notifications service.
I have created a question in "stackoverflow":http://stackoverflow.com/questions/22592042/qt-dbus-monitor-method-calls but it hasn't get much attention.

Any help appreciated.
