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... где сгенерированный код «Qt Signals/Slots editor»?

Clang Developers - Proposal: parsing Qt signals/slots… I would like to add support for recognising Qt's signal/slot mechanism to clang by using attributes.Qt's meta-type system also allows for "invokable methods", which can be called/invoked withoutThis is equivalent to how moc (Qt's Meta-Object Compiler) generates the meta-object for a QObject.
Technical FAQ - Qt Wiki
Signals & Slots | Qt 4.8 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 (or Q_SIGNAL), c++ - How usable is Qt without its preprocessing step So for using Qt with a primary reason for OpenGL software, it actually works fine without MOC. However, I can't see how a full application could be developed without using MOC. Which is a shame. This Qt MOC thing is a pain. I don't understand why so many C++ developers seem to find it … Signals & Slots — Qt for Python 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() Using std::function as parameter for slot and signal | Qt
How Qt Signals and Slots Work
Signals and slots are Qt mechanism, in process of compilations using moc (meta-object compiler), it is changed to callback functions.With that said, signals and slots can certainly be used without QEvents, although you’ll find that the original impetus for activating a signal will often be some kind of... Qt signals and slots for newbies - Qt Wiki
Verdigris is a header-only library that can be used with Qt. It uses macros to create a QMetaObject that is binary compatible with Qt's own QMetaObject without requiring moc. In other words, you can use Verdigris macros in your Qt or QML …
Note: Since the program is empty and has no QObject on his own, neither moc nor Verdigris were used. Qt5 and Qt4 themselves were compiled with moc as usual. Signals/Slots run-time performance. I built the Qt benchmarks for testing connecting and emitting of Qt signals. There is no difference between Verdigris or the normal Qt. Qt Signals and Slots - KDAB Use the information provided my the moc to nd the index of the signal and of the slot Keep in an internal map which signal is connected to what slots When emitting a signal, QMetaObject::activate is called. It calls qt metacall (generated by moc) with the slot index which call the actual slot

The Independent Qt Tutorial - Chapter 2 The signals and slots are what makes the different Qt components as reuseable as they are. They provide a mechanism through which it is possible to expose interfaces that can be freely interconnected. Qt fundamentals - BlackBerry Native Qt is a cross-platform application framework that's used to develop UI-driven apps. Qt uses and extends C++ through a code generator called the MOC (meta-object compiler). Qt Framework | Linux Touchscreen
