Sample code demonstrating multi monitor support in Qt
I need a sample code which demonstrates an application using multi monitor support on desktop.
Basically the application's main window should run on primary screen and its child widgets on other secondary screens.
See "QDesktopWidget":http://qt-project.org/doc/qt-5/qdesktopwidget.html and "QScreen":http://qt-project.org/doc/qt-5/qscreen.html.
QScreen and friends will not really help you here since they represent displays that are connected. AFAIK there is nothing that could tell you the potential maximum number of screens.
