Is an event loop always necessary on the thread that is supposed to execute the connected slot? It seems that emitting the signal works even if I don't have an event loop, and if the connected slot is on the same thread it executes directly. So basically once I want cross thread signals and slots, I need an event loop on the thread with the slots?

Signals and Slots. In Qt, we have an alternative to the callback technique: We use signals and slots. A signal is emitted when a particular event occurs. Qt's widgets have many predefined signals, but we can always subclass widgets to add our own signals to them. A slot is a function that is called in response to a particular signal.
Signals and slots are loosely coupled: A class which emits a signal neither knows nor cares which slots receive the signal. Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's parameters at the right time. Signals and slots can take any number of arguments of any type. Threads Events QObjects - Qt Wiki
