How Qt Signals and Slots Work - Part 2 - Qt5 New Syntax New overloads. The first one is the one that is much closer to the old syntax: you connect a signal from the sender to a slot in a receiver object. The two other overloads are connecting a signal to a static function or a functor object without a receiver. They are very similar and we will only analyze the first one in this article. c++ - signal slot issue in qt 5 - Stack Overflow You're using variable names, not function signatures, in your signal and slot names. You've got a signal connected to another signal, which is valid but doesn't do what you want (it's usually used to chain stuff like this: SomeChildWidget's signal -> MyClass1's signal -> MyClass2's slot). Copied or Not Copied: Arguments in Signal-Slot Connections? The conclusion from the above results is that we should pass arguments to signals and slots by const reference and not by value. This advice is true for both direct and queued connections. Even if the sender of the signal and the receiver of the slot are in different threads, we should still pass arguments …

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.
