What is the use of the Qt::Desktop window flag?
-
The "documentation":http://doc.qt.nokia.com/stable/qt.html shows:
Qt::Desktop 0x00000010 | Window Indicates that this widget is the desktop. This is the type for QDesktopWidget.Other flags in the same series tell the WM what type of window it is dealing with: does this flag turn the window into the desktop? (That sounds not really probable). What else would you use this flag for then?

There is a special widget called "QDesktopWidget":http://doc.qt.nokia.com/latest/qdesktopwidget.html, which allows for accessing screen information on multi-head systems. You cannot use it directly and you will have to use QApplication::desktop() to retrieve it.
The Qt::Desktop flag is (at least as far as I know) used internally only to distinguish the QDesktopWidget from other widgets and is not passed to any window manager.
