Hello,

Thanks for your answer.

But I took care of calling sender() as soon as I enter in the slot,
to store its value in a variable before printing it.
And it *works* in C++, so why not here ?
Now, each button to a different slot is not the solution here : this
is an example program, the real program contains a dynamically-build
form: so I've no idea of the real number of buttons (it may vary between
about 10, to more than 50...)

So, how to do in those cases ?

Sorry, this was mistyped :
