Qt WARNING: QObject::connect: No such signal QApplication::screenRemoved(QScreen *)

The following error occurs when running my virtual box 5.1 from terminal in Debian 8 and this error when I close virtualbox:

Qt WARNING: QObject::disconnect: No such signal QApplication::screenRemoved(QScreen *)

What should I do?

Answer Source

The "screenRemoved" is a singnal from "QGuiApplication".

And "QApplication" iherits "QGuiApplication".

It is all good. But this method is there from Qt5.4 version.


Please check your QT version. May be it is bit older.
