Try and nudge parents/carers towards the best practice for how to set
parental controls on a user, by linking them to appropriate external
content from people who know what they’re talking about.
This external content can vary in the translations so that parents are
pointed to appropriate localised guidelines. In the UK, for example,
this may be
https://www.nspcc.org.uk/keeping-children-safe/online-safety/.

This simplifies the UI, as nobody really understood the difference
between ‘Restrict Application Installation’ and ‘Restrict Application
Installation for Others’. Now there’s just a ‘Restrict Application
Installation’ checkbox, which controls application installation in the
home and system flatpak repos.
The underlying app-filter representation in libmalcontent still supports
restricting installation to them separately, but the UI will always set
them to the same value.
There is a suggestion that we may want to support user repos again in
future iff the user has added a remote to their user repo. However,
figuring that out for other users (which is what the admin would have to
do when setting this all up) starts to get tricky with permissions for
reading other users’ home directories. Skip that for the moment — we can
reconsider adding that option in future if someone argues a case for it.

This causes the controls on the main window to be centred at their full
width (when there’s enough window width to do so), rather than expanding
to fill the entire window.
It’s not currently possible with GTK+3 to easily set a maximum width
(of, say, 600px) to the column, without writing a custom widget (like
`HdyColumn` does).

When ordering commercial translations, at least one translator
translated these literally, eg "Sitio web de mal gusto" and
"créditos-de-traductor".
It's likely that translators familiar with GNOME would not make this
mistake, but let's be explicit anyway.
Get the system bus higher up in the application, so the same system bus
connection can be shared between different parts of the application if
needed in future.
This also means the synchronous I/O needed to connect to the bus is done
before the application UI is shown, which prevents it unnecessarily
blocking initialisation of the `MctUserControls` widget.

When unlocking malcontent-control while running as an unprivileged user
to edit *that* user’s parental controls, the `ChangeOwn` and `ReadOwn`
privileges should also be granted.
Otherwise a second polkit authorisation dialogue is popped up after
editing any of the parental controls, to get permission to save the
changes.
Signed-off-by: Philip Withnall <withnall@endlessm.com>
When malcontent-control is run as an unprivileged user (i.e. a child)
the fact that the unlock wording refers to ‘other users’ is a little
confusing, since the purpose of running malcontent-control was likely to
edit the parental controls for *this* user.
Adjust the wording to make this a little clearer.

They need to be re-used in gnome-initial-setup. The other widgets which
remain in malcontent-control don’t need to be used in g-i-s so can stay
where they are for now. They might move across to libmalcontent-ui later
if there’s a need for it.

If the user has the restrict applications dialogue open and has made
some changes, then installs/uninstalls a flatpak (for example) from
gnome-software in another window, then the list of apps in the restrict
applications dialogue will be reloaded and the user’s changes will be
lost.
Prevent that by not reloading when the set of installed apps changes.
This is not a long-term solution: ideally we’d diff the changes against
the list of apps in the restrict applications dialogue and only update
what’s changed.

Sometimes, when closing the application,
`flush_update_blacklisted_apps()` would be called after
`MctRestrictApplicationsSelector` had been destroyed, leading to a
critical.
This was because the `MctRestrictApplicationsDialog` was being disposed
early due to its `destroy-with-parent` property being set. The dispose
function of `MctUserControls` was run several times due to GTK calling
`g_object_run_dispose()`, and the critical would be emitted the second
time.
Make the dispose function’s call to `flush_update_blacklisted_apps()` be
safe for multiple dispose calls, and ensure the dialog isn’t destroyed
too early.

Add an unlock screen to the application, which is shown on startup if
the current user doesn’t have permission to view the parental controls

implies the various accounts-service actions we need.

Rather than having a scrollable listbox within a scrollable list of
widgets, move the listbox out to a separate dialogue.
This involves separating out all the code to query the apps, to get and
to set the app filter, from `MctUserControls` out into the new
`MctRestrictApplicationsSelector`. Most of it is unchanged, aside from
its interaction with the filter: the filter is now provided to the
widget by the calling code, rather than being queried by the widget
itself. The widget’s status can be queried into an
`MctAppFilterBuilder`, rather than being used to set the app filter
directly.
This commit redesigns the appearance of the relevant widgets in the main
window so that they follow the new list-box-like visual design. A
following commit will apply similar changes to the other widgest in the
main screen.

The application doesn’t hold a ref to some of the widgets it holds a
pointer to, since their ownership is controlled by the main window. The
main window’s lifecycle is controlled by the application, but its
dispose cycle runs at a slightly different time.
Hence, we should disconnect from the widget signals when we can, but
without holding a strong ref.
The error domain was renamed in libmalcontent, so we should use the new
domain rather than the compatibility defines.

This replicates the old interface from Endless’ gnome-control-center,
with no attempt to improve or rework it. That will come later.
It might not work fully.
It allows a user to be selected, and their parental controls to be
changed. It currently doesn’t filter the users.
It supports a simple ‘Loading’ screen, before displaying the main
interface. If loading fails (due to a D-Bus error with accountsservice),
an error page is displayed instead.

`ActUserManager` with an `MctCarousel` to provide an all-inclusive

It’s based off code from the user accounts panel of

over time (see
