Migrating from EggSMClient to GtkApplication
Migrating from EggSMClient to GtkApplication
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 | GtkApplication |
|---|---|
EggSMClient::quit-requested |
instead of calling will_quit(FALSE,...) in response to this signal, install an inhibitor |
EggSMClient::quit |
the GApplication::shutdown signal |
EggSMClient::quit-cancelled |
no replacement |
egg_sm_client_will_quit() |
instead of calling will_quit(FALSE,...), install an inhibitor |
egg_sm_client_end_session() |
no replacement |
As of the writing of this page, 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.
