Theory of Signals and Callbacks. In version 2.0, the signal system has been moved from GTK to GLib, therefore the functions and types explained in this section have a "g_" prefix rather than a "gtk_" prefix. We won't go into details about the extensions which the GLib 2.0 signal system has relative to the GTK 1.2 signal system.

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. Callbacks, events, signals and slots - it.toolbox.com However, the biggest reason I love Qt so much is the Signals and Slots model it uses. All of the programming languages and frameworks based on those programming languages have some method of communicating between different objects or functions. Chapter 29. Boost.Signals - 1.61.0 The Boost.Signals library is an implementation of a managed signals and slots system. Signals represent callbacks with multiple targets, and are also called publishers or events in similar systems. Signals are connected to some set of slots, which are callback receivers (also called event targets or subscribers), which are called when the ...

Signals and slots is a handy pattern for situations where one or more objects need to be informed of changes occuring elsewhere in the program much like a callback. Unlike callbacks, with this library it's possible to have multiple functions called on the occurence of an event. Implementation of Delegates in C++ using Signal and Slot ...
