Multithreading PyQt applications with QThreadPool Apr 15, 2017 · Qt provides the signals and slots framework which allows you to do just that and is thread-safe, allowing safe communication directly from running threads to your GUI frontend. Signals allow you to .emit values, which are then picked up elsewhere in your code by slot functions which have been linked with .connect. Custom Type Sending Example | Qt 4.8 Since the signals and slots mechanism is only concerned with the type, we can simplify the signatures of both the signal and slot when we make the connection. When the user clicks on the Send message button in either window, the message shown will be emitted in a signal that the other window will receive and display. Further Reading 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. Otherwise, the behavior is the same as the Queued Connection." How To Really, Truly Use QThreads; The Full Explanation

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. PyQt Signals and Slots - Tutorials Point The signal on its own does not perform any action. Instead, it is ‘connected’ to a ‘slot’. The slot can be any callable Python function. In PyQt, connection between a signal and a slot can be achieved in different ways. Following are most commonly used techniques − QtCore.QObject.connect(widget, QtCore.SIGNAL(‘signalname’), slot ...
