Yes. The SIGNAL / SLOT macros convert its parameter to a string constant, 
QObject::connect takes const char*.
The string is then parsed by QMetaObject::normalizedSignature, removing spaces 
etc.
The great advantage of this approach is that it works with DBus, QtScript, QML 
etc. The disadvantage is that connect arguments are not checked by the 
compiler - I manage again and again to include parameter names in connect.
