A session manager keeps track of applications that are 37cdf0e10cSrcweir running when the desktop shuts down and starts them again in the same 38cdf0e10cSrcweir state they were left when the desktop starts up the next time. To be able 39cdf0e10cSrcweir to do this the session manager needs cooperation from applications; 40cdf0e10cSrcweir applications have to provide sufficient information to be started again as 41cdf0e10cSrcweir well as restore the state they were left in. The normal flow of operation 42cdf0e10cSrcweir looks like this: 43cdf0e10cSrcweir 44cdf0e10cSrcweir <ol> 45cdf0e10cSrcweir <li>The user starts the desktop shutdown.</li> 46cdf0e10cSrcweir <li>The session manager informs all its connected applications 47cdf0e10cSrcweir about the pending shutdown.</li> 48cdf0e10cSrcweir <li>Each application saves its current state; while doing this it may 49cdf0e10cSrcweir <ul> 50cdf0e10cSrcweir <li>The application may request to interact with the user (e.g. to ask 51cdf0e10cSrcweir where to save documents). This request is necessary because at any one 52cdf0e10cSrcweir time only one application can iteract with the user. The session manager 53cdf0e10cSrcweir coordinates these requests and grants every application in need of user 54cdf0e10cSrcweir interaction a timeslot in which it may interact with the user</li> 55cdf0e10cSrcweir <li>try to cancel the whole shutdown; the session manager may or may 56cdf0e10cSrcweir not honor that request.</li> 57cdf0e10cSrcweir </ul> 58cdf0e10cSrcweir </li> 59cdf0e10cSrcweir <li>After saving is done the session manager signals all applications 60cdf0e10cSrcweir to exit.</li> 61cdf0e10cSrcweir <li>Applications answer the exit message by disconnecting from the 62cdf0e10cSrcweir session manager.</li> 63cdf0e10cSrcweir <li>After all applications have exited or a reasonable timeout the 64cdf0e10cSrcweir session manager kills all remaining applications and finally lets the 65cdf0e10cSrcweir desktop shut down.</li> 66cdf0e10cSrcweir*/ 67cdf0e10cSrcweirservice SessionManager 68cdf0e10cSrcweir{ 69cdf0e10cSrcweir /** XSessionManagerClient (of which there can only be one instance per 70cdf0e10cSrcweir process) provides an application's interface to the session manager. 71cdf0e10cSrcweir It keeps track of every listener inside the application and multiplexes 72cdf0e10cSrcweir the session manager's signals as well as requests to the session manager. 73cdf0e10cSrcweir */ 74cdf0e10cSrcweir interface XSessionManagerClient; 75cdf0e10cSrcweir 76cdf0e10cSrcweir}; 77cdf0e10cSrcweir 78cdf0e10cSrcweir}; }; }; }; 79cdf0e10cSrcweir 80cdf0e10cSrcweir#endif 81
