+ Constructs an application object with \a argc command line arguments
+ in \a argv. If \a GUIenabled is TRUE, a GUI application is
+ constructed, otherwise a non-GUI (console) application is created.
+ If \a SMEnabled is TRUE, session management support is enabled (default).
+
+ Set \a GUIenabled to FALSE for programs without a graphical user
+ interface that should be able to run without a window system.
+
+ Set \a SMEnabled to FALSE to disable session management.
+ Session management cannot be enabled at a later time if disabled here.
+
+ On X11, the window system is initialized if \a GUIenabled is TRUE.
+ If \a GUIenabled is FALSE, the application does not connect to the
+ X-server.
+ On Windows and Macintosh, currently the window system is always
+ initialized, regardless of the value of GUIenabled. This may change in
+ future versions of Qt.
+
+ The following example shows how to create an application that
+ uses a graphical interface when available.
