QThreads general usage - Qt Wiki The main thing in this example to keep in mind when using a QThread is that it's not a thread. It's a wrapper around a thread object. This wrapper provides the signals, slots and methods to easily use the thread object within a Qt project. To use it, prepare a QObject … 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. Qt.ConnectionType BlockingQueuedConnection public static final Qt.ConnectionType BlockingQueuedConnection Same as QueuedConnection , except that the current thread blocks until the slot has been delivered.This connection type should only be used for receivers in a different thread. Note that misuse of this type can lead to dead locks in your application.

The second connects the thread's started() signal to the processing() slot in the worker, causing it to start. Then the clean-up: when the worker instance emits finished(), as we did in the example, it will signal the thread to quit, i.e. shut down. We then mark the worker instance using the same finished() signal for deletion.
