Let's start with a bit of history. QMetaType was introduced in Qt 4.0. It was created in order to have the possibility to have asynchronous signals and slots ( Qt::QueuedConnection). The future of moc » Thiago Macieira's blog In fact, you can’t see this, but the old Qt historical repository began with moc being imported into CVS (files moc.l and moc.y). Since then, it’s been rewritten a couple of times, most recently for Qt 4 with a hand-written parser. Don’t be sub-class when subclassing | -Wmarc Let's get started by looking at some code: namespace MyProject { /*! \brief QLabel for MyProject This class is a drop-in replacement for QLabel. We need to subclass all widgets we use, because QStyle doesn't let us do all the things we want … Defending Qt | Those Darn Geeks
Qt in Education The Qt object model and the signal slot
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.
