Signals and slots - Wikipedia 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 The constraints - GNOME The first thread to create such a slot should be regarded as owning the relevant object for the purpose of creating further slots referencing any of its non-static methods using that function, or nulling those slots by disconnecting them or destroying the trackable Qt 4.4.3: Thread Support in Qt Qt provides thread support in the form of platform-independent threading classes, a thread-safe way of posting events, and signal-slot connections across threads. This makes it easy to develop portable multithreaded Qt applications and take advantage of

This is possible because each thread is allowed to have its own event loop.
