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.

Qt connects widgets by means of a nice designed scheme based on the idea that objectS may send signalS of different typeS to a single objectThis is a screenshot of the example code running. The main application creates dialogs A and B and then connects the signal from A to the signal slot in B.

Determine signals connected to a given slot in Qt - Stack ... There is no way to safely iterate the list of signal-slot connections without holding Qt's internal mutexes/semaphores. The signals and slots can come and go at any time, so at best you'd get a list that is not guaranteed to be correct - and thus useless. Whatever hooking you do in QObject::connect is by itself insufficient. The data you get ...
