Table of Contents
Description§
Gnome::Gtk4::LockButton is a widget to obtain and revoke authorizations needed to operate the controls.
UNKNOWN image§
=for image :class<inline> :src<asset_files/images/lock-button.png> :width<30\%>It is typically used in preference dialogs or control panels.
The required authorization is represented by a Gnome::Gio::Permission object. Concrete implementations of Gnome::Gio::Permission may use PolicyKit or some other authorization framework. To obtain a PolicyKit-based Gnome::Gio::Permission, use polkit_permission_new()`.
If the user is not currently allowed to perform the action, but can obtain the permission, the widget looks like this:

=for image :class<inline> :src<asset_files/images/lockbutton-locked.png> :width<30\%>and the user can click the button to request the permission. Depending on the platform, this may pop up an authentication dialog or ask the user to authenticate in some other way. Once the user has obtained the permission, the widget changes to this:

=for image :class<inline> :src<asset_files/images/lockbutton-unlocked.png> :width<30\%>and the permission can be dropped again by clicking the button. If the user is not able to obtain the permission at all, the widget looks like this:
UNKNOWN image§
=for image :class<inline> :src<asset_files/images/lockbutton-sorry.png> :width<30\%>If the user has the permission and cannot drop it, the button is hidden.
The text (and tooltips) that are shown in the various cases can be adjusted with the text-lock, text-unlock, tooltip-lock, tooltip-unlock and tooltip-not-authorized properties.
