As you know, a mutex must be used between threads sharing data. There is also the problem of sharing Qt implicitly shared objects between threads. I can see that you pass a QString (implicitly shared) from the worker object to the main GUI thread using a signal and slot.
Signals and slots are used for communication between objects. The signals and slots mechanism is a central feature of Qt and probably the part that differs most from the features provided by other frameworks. Qt Signals & Slots: How they work | nidomiro The standard use-case of Signals & Slots is interacting with the UI from the code while remaining responsive. This is nothing more than a specific version of „communicating between threads“. Another benefit of using them is loosely coupled objects. The QObject emitting the Signal does not know the Slot- QObject and vice versa Support for Signals and Slots — PyQt 5.11 Reference Guide Support for Signals and Slots¶ One of the key features of Qt is its use of signals and slots to communicate between objects. Their use encourages the development of reusable components. A signal is emitted when something of potential interest happens. A slot is a Python callable.

When a user takes an action — clicking on a button, selecting a value in a combo box, typing in a text box — the widget in question emits a signal.This signal does nothing, by itself; it must be connected to a slot, which is an object that acts as a recipient for a signal and, given one, acts on it. pyqt5/examples/threads at master · baoboa/pyqt5 · GitHub PyQt makes it easier than ever to write multithreaded applications. More classes have been made usable from non-GUI threads, and the signals and slots mechanism can now be used to communicate between threads. Additionally, it is now possible to move objects between threads.
Signals and slots is a language construct introduced in Qt for communication between objects which makes it easy to implement the observer pattern while avoiding boilerplate code.The concept is that GUI widgets can send signals containing event information which can be received by other widgets / controls using special functions known as slots. This is similar to C/C++ function pointers, but ...
