43 : : * MctUserControls:
44 : : *
45 : : * A group of widgets which allow setting the parental controls for a given
46 : : * user.
47 : : *
48 : : * If #MctUserControls:user is set, the current parental controls settings for
49 : : * that user will be loaded and displayed, and any changes made via the controls
50 : : * will be automatically saved for that user (potentially after a short
51 : : * timeout).
52 : : *
53 : : * If #MctUserControls:user is unset (for example, if setting the parental
54 : : * controls for a user account which hasn’t yet been created), the controls can
55 : : * be initialised by setting:
56 : : * * #MctUserControls:app-filter
57 : : * * #MctUserControls:user-account-type
58 : : * * #MctUserControls:user-locale
59 : : * * #MctUserControls:user-display-name
60 : : *
61 : : * When #MctUserControls:user is unset, changes made to the parental controls
62 : : * cannot be saved automatically, and must be queried using
63 : : * mct_user_controls_build_app_filter(), then saved by the calling code.
64 : : *
65 : : * As parental controls are system settings, privileges are needed to view and
66 : : * edit them (for the current user or for other users). These can be acquired
67 : : * using polkit. #MctUserControls:permission is used to query the current
68 : : * permissions for getting/setting parental controls. If it’s %NULL, or if
69 : : * permissions are not currently granted, the #MctUserControls will be
70 : : * insensitive.
