Hello,
I explain my problem and I hope that someone may give me the solution.

Currently I am developing a small application with graphical interfaces and that with Java and Qt

So I create a QTable (a table) and within each line there are QLabels for text and a button that emits a signal.

My table is composed of several lines and therefore more buttons, I want to know what is the button that issued the last signal or in other words which button was clicked.

I searched the web for a few hours but no way because the solution is either in C + + and I can not transcribe it in java or I have not found the solution.

thank you
