@ronaldon so which line is line 80? Seems it is the copy constructor for QFile Does a copy constructor for QFile even exist in the framework?

filenameis of typeQString.MainWindow::loadFile(QFile fileName)is the signature [from your stackoverflow post, thanks to @Christian-Ehrlicher, where unlike here you give the necessary information], so accepts aQFile, with an unhelpfully-named formal parameter. [Furthermore, this is passing-by-value-copy, which is not allowed forQFileas it is derived fromQObject.]- So
MainWindow::loadFile(fileName);is not going to work.
What else is there to say?
Also, it's not very fair to those who try to answer here that you post the same question, with more detail, on stackoverflow, do not reference that here, say there that you have your answer, and leave this question here still open....
