How Qt Signals and Slots Work - Woboq The connection mechanism uses a vector indexed by signals. But all the slots waste space in the vector and there are usually more slots than signals in an object. 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. Qt for Beginners - Qt Wiki This section can be skipped for now if you only want to program with Qt. Just know that you need to put SIGNAL and SLOT around the signals and slots while calling connect. If you want to know how Qt works, it is better to read this. The Meta Object.

Signals & Slots | Qt Core 5.12.3 Signals and slots are loosely coupled: A class which emits a signal neither knows nor cares which slots receive the signal. Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's parameters at the right time. Signals and slots can take any number of arguments of any type.

The connection mechanism uses a vector indexed by signals. But all the slots waste space in the vector and there are usually more slots than signals in an object. 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.

The signal/slot argument lists is not compatible (*) The elements marked with a (*) do not fully apply to the new connection syntax, which performs checks at compile-time. When QObject::connect() fails it returns false and it emits a warning which gets typically printed on the console, if you have one, or in Creator’s output pane.
