This is the sequel of my previous article explaining the implementation details of the signals and slots. In the Part 1, we have seen the general principle and how it works with the old syntax. How Qt Signals and Slots Work - Part 3 - Queued and Inter… In the first part, we saw that signals are just simple functions, whose body is generated by moc. They are just calling QMetaObject::activate, with an array of pointers to arguments on the stack. Proof Of Concept: Re-implementing Qt moc using libclang It's role is to handle the Qt's extension within the C++ code to offer introspection and enable the Qt signals and slots.

MOC, the Meta Object Compiler. The Qt signals/slots and property system are based on the ability to introspect the objects at runtime.QtScript and QML would have hardly been possible without that ability. C++ does not offer introspection support natively, so Qt comes with a tool to provide it.
Signals and slots are used for communication between objects. The signals and slotsThe signals and slots mechanism is type safe: The signature of a signal must match the signatureThis example illustrates that objects can work together without needing to know any information about each other.

With moc, we have turned this disadvantage into an advantage, and added the flexibilityAnother benefit is that we can explore an object's signals and slots at runtime. We can establish connections using type-safe call-by-name, without having to know the exact types of the objects we are connecting.
Automatic Connections: using Qt signals and slots the easy… One key and distinctive feature of Qt framework is the use of signals and slots to connect widgets and related actions. But as powerful the feature is, it may look compelling to a lot of developers not used to such a model... Qt Toolkit - Signals and Slots | Moc output Signals and slots are used for communication between objects. The signal/ slot mechanism is a central feature of Qt and probably the part that differs most from other toolkits. In most GUI toolkits widgets have a callback for each action they can trigger. Qt 4.5: Signals and 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 thatBy running the moc on class definitions that contain signals or slots, a C++ source file is produced which should be compiled and linked with the other...
It tells Qt not to define the moc keywords signals, slots, and emit, because these names will be used by a 3rd party library, e.g. Boost. Then to continue using Qt signals and slots with the no_keywords flag, simply replace all uses of the Qt moc keywords in your sources with the corresponding Qt macros Q_SIGNALS()
Signal & Slots Qt's event handling mechanism Signals are emitted by widgets when something happens Slots are used to handle signals Most of theSlots are normal methods Signals are just declarations used by the moc compiler. Example class Counter : public QObject { Q_OBJECT public...
