-  \class QApplication
-  \brief The QApplication class manages the GUI application's control
-  flow and main settings.
-
-  \ingroup application
-  \mainclass
-
-  It contains the main event loop, where all events from the window
-  system and other sources are processed and dispatched. It also
-  handles the application's initialization and finalization, and
-  provides session management. It also handles most system-wide and
-  application-wide settings.
-
-  For any GUI application that uses Qt, there is precisely one
-  QApplication object, no matter whether the application has 0, 1, 2
-  or more windows at any time. For non-GUI Qt applications, use
-  QCoreApplication instead, which doesn't depend on the \l QtGui
-  library.
-
-  The QApplication object is accessible through the instance()
-  function which return a pointer equivalent to the global qApp
-  pointer.
-
-  QApplication's main areas of responsibility are:
-  \list
-
-  \o It initializes the application with the user's desktop settings
-  such as palette(), font() and doubleClickInterval(). It keeps track
-  of these properties in case the user changes the desktop globally, for
-  example through some kind of control panel.
-
-  \o It performs event handling, meaning that it receives events
-  from the underlying window system and dispatches them to the relevant
-  widgets. By using sendEvent() and postEvent() you can send your own
-  events to widgets.
-
-  \o It parses common command line arguments and sets its internal
-  state accordingly. See the \link QApplication::QApplication()
-  constructor documentation\endlink below for more details about this.
-
-  \o It defines the application's look and feel, which is
-  encapsulated in a QStyle object. This can be changed at runtime
-  with setStyle().
-
-  \o It specifies how the application is to allocate colors.
-  See setColorSpec() for details.
-
-  \o It provides localization of strings that are visible to the user
-  via translate().
-
-  \o It provides some magical objects like the desktop() and the
-  clipboard().
-
-  \o It knows about the application's windows. You can ask which
-  widget is at a certain position using widgetAt(), get a list of
-  topLevelWidgets() and closeAllWindows(), etc.
-
-  \o It manages the application's mouse cursor handling,
-  see setOverrideCursor()
-
-  \o On the X window system, it provides functions to flush and sync
-  the communication stream, see flushX() and syncX().
-
-  \o It provides support for sophisticated \link
-  session.html session management \endlink. This makes it possible
-  for applications to terminate gracefully when the user logs out, to
-  cancel a shutdown process if termination isn't possible and even to
-  preserve the entire application's state for a future session. See
-  isSessionRestored(), sessionId() and commitData() and saveState()
-  for details.
-
-  \endlist
-
-  Since the QApplication object does so much initialization, it
-  \e{must} be created before any other objects related to the user
-  interface are created.
-
-  Since it also deals with common command line arguments, it is
-  usually a good idea to create it \e before any interpretation or
-  modification of \c argv is done in the application itself.

-  \o -bg or \c -background \e color, sets the default background color
-        and an application palette (light and dark shades are calculated).
-  \o -fg or \c -foreground \e color, sets the default foreground color.
-  \o -btn or \c -button \e color, sets the default button color.

-
-  A session manager in a desktop environment (in which Qt GUI
-  applications live) keeps track of a session, which is a group of
-  running applications, each of which has a particular state. The
-  state of an application contains (most notably) the documents the
-  application has open and the position and size of its windows.
-
-  The session manager is used to save the session, e.g. when the
-  machine is shut down, and to restore a session, e.g. when the
-  machine is started up. We recommend that you use QSettings to save
-  an individual application's settings, e.g. window positions,
-  recently used files, etc. When the application is restarted by the
-  session manager, you can restore the settings.
-
-  QSessionManager provides an interface between the application
-  and the session manager so that the program can work well with the
-  session manager. In Qt, session management requests for action are
-  handled by the two virtual functions QApplication::commitData()
-  and QApplication::saveState(). Both provide a reference to a
-  session manager object as argument, to allow the application to
-  communicate with the session manager. The session manager can only
-  be accessed through these functions.
-
-  No user interaction is possible \e unless the application gets
-  explicit permission from the session manager. You ask for permission
-  by calling allowsInteraction() or, if it's really urgent,
-  allowsErrorInteraction(). Qt does not enforce this, but the session
-  manager may.
-
-  You can try to abort the shutdown process by calling cancel(). The
-  default commitData() function does this if some top-level window
-  rejected its closeEvent().
-
-  For sophisticated session managers provided on Unix/X11, QSessionManager
