Qt was the first library that allowed to handle an event in a method of a specific object instance - which is what you actually want most of the time. Unfortunately Qt Signal/Slots are not really well integrated into the language. This is mainly due to the preprocessor mechanism that works only on the declarations.

See full list on wiki.qt.io You can't call Qt functions from Unix signal handlers. The standard POSIX rule applies: You can only call async-signal-safe functions from signal handlers. See Signal Actions for the complete list of functions you can call from Unix signal handlers. But don't despair, there is a way to use Unix signal handlers with Qt.

So from Qt 4.6, a new internal signal index which only includes the signal index is used. While developing with Qt, you only need to know about the absolute method index. But while browsing the Qt's QObject source code, you must be aware of the difference between those three. How Connecting Works.

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.Here is the code of a signal, as generated by moc: (from part 1)
