<interface name="org_kde_kwin_idle" version="1">

<description summary="User idle time manager">
|
||||
This interface allows to monitor user idle time on a given seat. The interface
|
||||
allows to register timers which trigger after no user activity was registered
|
||||
on the seat for a given interval. It notifies when user activity resumes.
|
||||
|
||||
This is useful for applications wanting to perform actions when the user is not
|
||||
interacting with the system, e.g. chat applications setting the user as away, power
|
||||
management features to dim screen, etc..
