There seems to be two ways to do this. One is using one of the QScreen 
signals:

   http://doc.qt.io/qt-5/qscreen.html

However, another one seems to be using QDesktopWidget signals:

   http://doc.qt.io/qt-5/qdesktopwidget.html

QApplication has static functions to get the current QDesktopWidget, the 
current QScreen primary screen and all screens. It also has signals to 
get notified of screen changes.
