Support for Signals and Slots — PyQt 5.10.1 Reference Guide A signal may be connected to many slots. A signal may also be connected to another signal. Signal arguments may be any Python type. A slot may be connected to many signals. Connections may be direct (ie. synchronous) or queued (ie. asynchronous). Connections may be made across threads. Signals may be disconnected. Development/Tutorials/Python introduction to signals and slots Signals do nothing alone, but once connected to a slot, the code in the slot will be executed whenever the signal is emitted. In the Python programs, every function is a slot. It is possible to connect one signal to multiple slots, and to connect slots consecutively. "How to use QThread in the right way (Part 1)" — 1+1=10 Aug 05, 2013 · The signal timeout() emitted from main thread, As timer and worker live in different threads, their connection type is queued connection. The slot get called in its living thread, which is the sub-thread. Thanks to a mechanism called queued connections, it is safe to connect signals and slots across different threads.

Fundamentals of Qt - Objects in Qt, part 2/3 - Signals and slots… Thread-Safety - 1.49.0 - It is expected that slot objects will be created then connected to a signal in a single thread. Once they have been copied into a signal's slot list, they are protected by the mutex associated with each signal-slot connection. The signals2::trackable class does NOT provide thread-safe automatic connection management. In particular, it leaves Threads and QObjects | Qt 5.12 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. Otherwise, the behavior is the same as the Queued Connection."

Problem with signal-slot connection across threads [SOLVED ... 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?

Communicating with the Main Thread - InformIT Nov 06, 2009 · The solution for communicating from a secondary thread to the main thread is to use signal–slot connections across threads. Normally, the signals and slots mechanism operates synchronously, meaning that the slots connected to a signal are invoked immediately when the signal is emitted, using a direct function call.
