Change notification
|

|
|

GConf requires you to call gconf_client_add_dir() and
|
|
Packit |
ae235b |
gconf_client_notify_add() to get change notification. With
|
|
Packit |
ae235b |
GSettings, this is not necessary; signals get emitted automatically
|
|
Packit |
ae235b |
for every change.
|
|
Packit |

|
|

|
|

The “changed” signal is emitted for each changed key.
|
|
Packit |
ae235b |
There is also a “change-event” signal that you can handle
|
|
Packit |
ae235b |
if you need to see groups of keys that get changed at the same time.

GSettings also notifies you about changes in writability of keys,
|
|
Packit |
ae235b |
with the “writable-changed” signal (and the
|
|
Packit |
ae235b |
“writable-change-event” signal).
