| /** The SessionManager service provides an interface to the session manager |
| of the desktop. A session manager keeps track of applications that are |
| running when the desktop shuts down and starts them again in the same |
| state they were left when the desktop starts up the next time. To be able |
| to do this the session manager needs cooperation from applications; |
| applications have to provide sufficient information to be started again as |
| well as restore the state they were left in. The normal flow of operation |
| looks like this: |
| |
| <ol> |
| <li>The user starts the desktop shutdown.</li> |
| <li>The session manager informs all its connected applications |
| about the pending shutdown.</li> |
| <li>Each application saves its current state; while doing this it may |
| <ul> |
| <li>The application may request to interact with the user (e.g. to ask |
| where to save documents). This request is necessary because at any one |
| time only one application can iteract with the user. The session manager |
| coordinates these requests and grants every application in need of user |
| interaction a timeslot in which it may interact with the user</li> |
| <li>try to cancel the whole shutdown; the session manager may or may |
| not honor that request.</li> |
| </ul> |
| </li> |
| <li>After saving is done the session manager signals all applications |
| to exit.</li> |
| <li>Applications answer the exit message by disconnecting from the |
| session manager.</li> |
| <li>After all applications have exited or a reasonable timeout the |
| session manager kills all remaining applications and finally lets the |
| desktop shut down.</li> |
