GUI crash using threads

That looks kind of OK.
Can you make a qDebug() output in MainWindow::Emissio_estat() and see if it gets called?

Btw, the Forum has code tags for posting code snippets. code and /code in square brackets

Thank you very much for your replay, and sorry for the late of mine.
Finally I've fixed the mistake, it was about another part of the code...
Eventhough thanks a lot!
