Long Term Support Release New Features in Qt 5.15 - Qt 6.0 Development. A Deeper Look at Signals and Slots ScottCollins2005.12.19 what are signals and slots? Slots, slots everywhere. By Ramon Talavera Qt connects widgets by means of a nice designed scheme based on the idea that objectS may send signalS of different typeS to a single object instance. 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. Signals and slots are used for communication between objects. The signals and slots mechanism is a central feature of Qt and probably the part that differs most from the features provided by other frameworks. Signals and slots are made possible by Qt's meta-object system.
