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 … Moc myths debunked All the moc generated tables go in const arrays that are stored in the shareable read-only data segment. CopperSpice, on the other hand, registers the QMetaObject data (information about signals, slots and properties) at run time. How Qt Signals and Slots Work Qt is well known for its signals and slots mechanism. But how does it work? In this blog post, we will explore the internals of QObject and QMetaObject and discover how signals and slot work under the hood.

Traditional syntax: SIGNAL and SLOT() QtCore.SIGNAL() and QtCore.SLOT() macros allow Python to interface with Qt signal and slot delivery mechanisms. This is the old way of using signals and slots. The example below uses the well known clicked signal from a QPushButton.The connect method has a non python-friendly syntax. How to Use Signals and Slots - Qt Wiki A developer can choose to connect to a signal by creating a function (a slot) and calling the connect() function to relate the signal to the slot. Qt's signals and slots mechanism does not require classes to have knowledge of each other, which makes it much easier to develop highly reusable classes.

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()

(For an explanation of the inner working of the signals and slots, read one of my previous articles: How Qt signals and slots work.)
