The documentation you want is at
http://doc.trolltech.com/4.5/qt.html#ConnectionType-enum. This describes the
different behaviors available when signals and threads interact.

The default connection type is Qt:Autoconnect which behaves differently
based on if you are send a signal to your own thread or to a different
thread.
