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. Multithreaded programming for multicore architectures with Qt ...

Signals and Slots. In Qt, we have an alternative to the callback technique: We use signals and slots. A signal is emitted when a particular event occurs. Qt's widgets have many predefined signals, but we can always subclass widgets to add our own signals to them. A slot is a function that is called in response to a particular signal. Qt 4.7.0: Threads and QObjects On the other hand, you can safely emit signals from your QThread::run() implementation, because signal emission is thread-safe. Signals and Slots Across Threads. Qt supports these signal-slot connection types: Auto Connection (default) The behavior is the same as the Direct Connection, if the emitter and receiver are in the same thread. The How to Use Signals and Slots - Qt Wiki A developer can choose to connect to a signal by creating a function (a slot) and calling the connect() function to relate the signal to the slot. Qt's signals and slots mechanism does not require classes to have knowledge of each other, which makes it much easier to develop highly reusable classes.
