How Qt Signals and Slots Work - Part 2 - Qt5 New Syntax This is the sequel of my previous article explaining the implementation details of the signals and slots. In the Part 1 , we have seen the general principle and how it works with the old syntax.
This is C++ fundamentals, and has nothing to do with Qt. Third: The connect function takes its signal or slot arguments (within SIGNAL() and SLOT() macros) always without the class or namespace scope arguments, only the pure method name with the argument types. ...
