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.

Getting the most of signal/slot connections : Viking Software ... Signals and slots were one of the distinguishing features that made Qt an exciting and innovative tool back in time. But sometimes you can teach new tricks to an old dog, and QObjects gained a new way to connect between signals and slots in Qt5, plus some extra features to connect to other functions which are not slots. Qt 5.5 connect fails using new signals and slots syntax with ... The problem is the way the Qt's new overloaded QObject::connect methods try to identify an object's signal from a member function pointer (MFP). It's based on a false assumption that MFP values can be cast to a void* values for equlity comparisons. The ISO C++ standard specifies that casting an MFP to void* is illegal and its behavior undefined. Qt 5 and C++11: Lambdas Are Your Friend | Custom Software ... I believe the signal/slot mechanism has found its soul mate in C++11 lambda functions. What’s this signal/slot thingy?
