A "session" is a kind of record of the state of the system, e.g. which applications were run at start up and which applications are currently running. 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. Use QSettings to save and restore an individual application's settings, e.g. window positions, recently used files, etc. .PP -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. +TQSessionManager provides an interface between the application and the session manager so that the program can work well with the session manager.

You ask for permission by calling allowsInteraction() or, if it's really urgent, allowsErrorInteraction(). TQt does not enforce this, but the session manager may. .PP 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(). .PP -For sophisticated session managers provided on Unix/X11, QSessionManager offers further possibilites to fine-tune an application's session management behavior: setRestartCommand(), setDiscardCommand(), setRestartHint(), setProperty(), requestPhase2().
