Basic Example of using a pure python Signal/Slot implementation ...
I am having difficulty grasping what happens when for eg. two different signals are connected to two different slots and when one slot is not done, the other slots' signal is emitted (for both slots connected to their respective signals in a direct connection) where the application only has "one" thread. Threads and QObjects | Qt 4.8 Signals and Slots Across Threads. Qt supports these signal-slot connection types: Auto Connection (default) If the signal is emitted in the thread which the receiving object has affinity then the behavior is the same as the Direct Connection.

Qt - Signals and Slots | qt Tutorial Signals and slots are used for communication between objects. The signals and slots mechanism is a central feature of Qt. In GUI programming, when we change one widget, we often want another widget to be notified. More generally, we want objects of any kind to be able to communicate with one another.
In Qt, signals and slots have taken over from these messy function pointers.A protected slots: section contains slots that this class and its subclasses may connect signals to. This is intended for slots that are part of the class' implementation rather than its interface towards the rest of the world.
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.
Operations are scheduled and performed when control returns to Qt's event loop. When the operation is finished, QTcpSocket emits a signal.
