qt documentation: The new Qt5 connection syntax. Example. The conventional connect syntax that uses SIGNAL and SLOT macros works entirely at runtime, which has two drawbacks: it has some runtime overhead (resulting also in binary size overhead), and there's no compile-time correctness checking. The new syntax addresses both issues. Before checking the syntax in an example, we'd better know ... c++ - Connecting overloaded signals and slots in Qt 5 ...

The QApplication class has a slot quit() function, which can be called when you want to terminate your application.
The code inside the Worker's slot would then execute in a separate thread. However, you are free to connect the Worker's slots to any signal, from any object, in any thread. It is safe to connect signals and slots across different threads, thanks to a mechanism called queued connections.
