The D-Bus signatures are explained here:
http://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-signatures

However, it might be way more convenient to use the QT4_ADD_DBUS_INTERFACE 
CMake macro together with the XML introspection file to let the build process 
generate an interface class for you. You can then do method calls as on a 
local object and in most cases do not have to worry about D-Bus types.

Cheers,
Kevin
