Qt is a cross-platform application framework that's used to develop UI-driven apps. Qt uses and extends C++ through a code generator called the MOC (meta-object compiler).
Qt signal slots and gmock - Google Groups You didn't declare rxsignal as a slot. You made it a regular public function, hence why it says no slot exists by that name. However, the Qt moc cannot parse the mock macro. So you cannot directly declare MOCK_METHODs as ... Copied or Not Copied: Arguments in Signal-Slot Connections ...

How Qt Signals and Slots Work - Woboq Qt is well known for its signals and slots mechanism. But how does it work? In this blog post, we will explore the internals of QObject and QMetaObject and discover how signals and slot work under the hood. In this blog article, I show portions of Qt5 code, sometimes edited for formatting and brevity. Qt signal-slot duplication code avoidance | Qt Forum @arsinte_andrei said in Qt signal-slot duplication code avoidance:. you made me confused about what you need - you can have many classes that emit the very same name signal (like readyread - in qtcpsocket, qabstractsocket, qudpsocket and so on...) but you make the difference between them when you use connect... - you have to select the sender.. so how can it be any confusions at all??
I am quite new to Qt and I have worked away with their slots & signals without too many problems until in one occasion on a new project, I was not able to get my signal connected to my slot… that kept me stuck for a good while, double checking that I had done all I thought was necessary for it to work correctly (QObject inheritance, proper ...
this is, we stated the sender object's name, the signal we want to connect, the receiver object's name and the slot to connect the signal to.
