[Evolution-hackers] How do I detect changes in the sync_offline checkbox?

[Jules Colding <colding omesc com>]

Hi,

Is there a standard way to detect whenever a user checks or un-checks
the "Copy folder content locally for offline operation" check box(*)
short of creating a thread to check periodically? 

A call-bak function or something like that?


Thanks,
