In QSA, it is possible to use Qt's meta-object system to communicate between objects created in the C++ code and objects created in a script. Qt 4's meta-object system makes this sort of extension possible, with a little bit of hackery. This article will get you started writing a dynamic signals and slots binding layer for Qt 4. Using QML Bindings in C++ Applications | Qt 4.8 Using QML Bindings in C++ Applications QML is designed to be easily extensible to and from C++. The classes in the Qt Declarative module allow QML components to be loaded and manipulated from C++, and through Qt's meta-object system , QML and C++ objects can easily communicate through Qt signals and slots. How to add one parameter to the clicked SIGNAL? | Qt Forum @ChristianMontero @ChristianMontero said in How to add one parameter to the clicked SIGNAL?. @ambershark hey one last thing :/ where could I read to understand the second option that you gave me, I mean to emit a different Clicked signal, because for the purpose of the application the next step it's to pass the text of each button to a string and I have to acces to every button as an element Passing Data to a Slot | Qt Forum Passing Data to a Slot Passing Data to a Slot.

Fortunately, the Qt folks provided a solution that can make passing extra arguments to slots relatively simple. This is the QSignalMapper class. I'll just show a partial code sample. Suppose we have two different QAction objects, and we want to connect both to the slot:
New Signal Slot Syntax - Qt Wiki
Qt Signals and Slots sending arrays of structures
Qt allows us to connect multiple signals to the same signal or slot. This can be useful when we provide the user with many ways of performing the same operation. Sometimes, however, we would like the slot to behave slightly differently depending on which widget invoked it.
New-style Signal and Slot Support — PyQt 4.12.3 Reference Guide
Signals and Slots. Signals and Slots are a feature of Qt used for communication between objects. When something happens to an object, it can emit a signal. Zero or more objects can listen for this signal using a slot, and act on it. The signal doesn’t know if anything is listening to it, and the slot doesn’t know what object called it. Mapping Many Signals to One - Qt Documentation
Qt for Beginners - Qt Wiki This section can be skipped for now if you only want to program with Qt. Just know that you need to put SIGNAL and SLOT around the signals and slots while calling connect. If you want to know how Qt works, it is better to read this. The Meta Object. Qt provides a meta-object system. Meta-object (literally "over the object") is a way to achieve ...
