Qt in Education The Qt object model and the signal slot Qt events signals and slots properties memory management. The QObject QObject is the base class to most Qt classes. Examples of exceptions are: Classes that need to be lightweight such as graphical primitives Data containers (QString, QList, QChar, etc) Classes that needs to be copyable, as QObject s

QGraphicsObject Class Reference - SourceForge.net Detailed Description. The QGraphicsObject class provides a base class for all graphics items that require signals, slots and properties. The class extends a QGraphicsItem with QObject's signal/slot and property mechanisms. Implementing my own signal slot mechanism using C++11 I programmed in C# and I used the Qt framework. Both of them have their own signal slot mechanism which are really powerful. I looked at several implementations in C++ and based on what I learnt from Signals and Slots in Qt5 - Woboq As you might have seen in the previous example, the slot was just declared as public and not as slot. Qt will indeed call directly the function pointer of the slot, and will not need moc introspection anymore. (It still needs it for the signal) But what we can also do is connecting to any function or functor: Qt Fundamentals: Qt Basics - Aalborg Universitet
