EggSMClient provides 'session management' support for applications. This means a number of things:
- logout notification and negotiation
- application state saving
- restarting of applications with saved state
EggSMClient supports this functionality to varying degrees on Windows and OS X, as well as with XSMP and D-Bus based session managers in X11.
Starting with GTK+ 3.4, GtkApplication supports logout notification and negotiation similar to EggSMClient.
|EggSMClient::quit-requested||instead of calling will_quit (FALSE,...) in response to this signal, install an inhibitor|
|EggSMClient::quit||the “shutdown” signal|
|egg_sm_client_will_quit||instead of calling will_quit (FALSE,...), install an inhibitor|
At this point, GtkApplication has no special support for state saving and restarting. Applications can use GSettings or GKeyFile and save as much state as they see fit in response to “shutdown” or whenever they consider appropriate.
