* MctUserControls:
|
||
*
|
||
* A group of widgets which allow setting the parental controls for a given
|
||
* user.
|
||
*
|
||
* If #MctUserControls:user is set, the current parental controls settings for
|
||
* that user will be loaded and displayed, and any changes made via the controls
|
||
* will be automatically saved for that user (potentially after a short
|
||
* timeout).
|
||
*
|
||
* If #MctUserControls:user is unset (for example, if setting the parental
|
||
* controls for a user account which hasn’t yet been created), the controls can
|
||
* be initialised by setting:
|
||
* * #MctUserControls:app-filter
|
||
* * #MctUserControls:user-account-type
|
||
* * #MctUserControls:user-locale
|
||
* * #MctUserControls:user-display-name
|
||
*
|
||
* When #MctUserControls:user is unset, changes made to the parental controls
|
||
* cannot be saved automatically, and must be queried using
|
||
* mct_user_controls_build_app_filter(), then saved by the calling code.
|
||
*
|
||
* As parental controls are system settings, privileges are needed to view and
|
||
* edit them (for the current user or for other users). These can be acquired
|
||
* using polkit. #MctUserControls:permission is used to query the current
|
||
* permissions for getting/setting parental controls. If it’s %NULL, or if
|
||
* permissions are not currently granted, the #MctUserControls will be
|
||
* insensitive.
