Signals and Slots in Qt5 - Woboq No compile time check: All the checks are done at run-time by parsing the strings. That means if you do a typo in the name of the signal or the slot, it will compile but the connection will not be made, and you will only notice a warning in the standard output. Since it operates on the strings, the type names of the slot must match exactly the ... I STRONGLY NEED to know slot where signal is connected to. It uses LOTS of Qt features and I cannot turn to other framework. I will not implement another signal-slot subsystem by my own.

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. Since signals and slots are type-safe, type errors are reported as warnings and do not cause crashes to occur. For example, if a Quit button's What do I do if a slot is not invoked? - KDAB Qt automatically breaks a signal/slot connection if either the sender or the receiver are destroyed (or if context object is destroyed, when using the new connection syntax and connecting to free functions).
