- * SECTION:polkitlockbutton

- * @title: PolkitLockButton

- * @short_description: Widget for obtaining/revoking authorizations

- * @stability: Stable

- *

- * #PolkitLockButton is a widget that can be used in control panels to

- * allow users to obtain and revoke authorizations needed for the

- * control panel UI to function.

- *

- * If the user lacks the authorization but authorization can be

- * obtained through authentication, the widget looks like this

- * <mediaobject id="lock-button-locked">

- * <imageobject>

- * <imagedata fileref="polkit-lock-button-locked.png" format="PNG"/>

- * </imageobject>

- * </mediaobject>

- * and the user can click the button to obtain the authorization. This

- * will pop up an authentication dialog.

- * Once authorization is obtained, the widget changes to this

- * <mediaobject id="lock-button-unlocked">

- * <imageobject>

- * <imagedata fileref="polkit-lock-button-unlocked.png" format="PNG"/>

- * </imageobject>

- * </mediaobject>

- * and the authorization can be dropped by clicking the button.

- * If the user is not able to obtain authorization at all, the widget

- * looks like this

- * <mediaobject id="lock-button-unlocked-not-authorized">

- * <imageobject>

- * <imagedata fileref="polkit-lock-button-not-authorized.png" format="PNG"/>

- * </imageobject>

- * </mediaobject>

- * If the user is authorized (either implicitly via the .policy file

- * defaults or through e.g. Local Authority configuration) and no

- * authentication is necessary and the Authority Implementation

- * supports lock-down, the widget looks like this

- * <mediaobject id="lock-button-unlocked-lock-down">

- * <imageobject>

- * <imagedata fileref="polkit-lock-button-lock-down.png" format="PNG"/>

- * </imageobject>

- * </mediaobject>

- * allowing the user to lock down the action. The lockdown can be

- * removed by right clicking the button - the user can discover this

- * through the tooltip. If the Authority implementation does not

- * support lockdown, the widget will be hidden.

- *

- * Finally, if the user is not authorized but authorization can be

- * obtained and the obtained authorization will be a one-shot

- * authorization, the widget will be hidden. This means that any

- * attempt to use the Mechanism that requires authorization for the

- * specified action will always prompt for authentication. This

- * condition happens exactly when

- * (!polkit_lock_button_get_is_authorized() &&

- * polkit_lock_button_get_can_obtain() &&

- * !polkit_lock_button_get_is_visible()) is %TRUE.

- *

- * Typically #PolkitLockButton is only useful for actions where

- * authorization is obtained through authentication (and retained) or

- * where users are implictly authorized (cf. the defaults specified in

- * the <literal>.policy</literal> file for the action) but note that

- * this behavior can be overridden by the Authority implementation.

- *

- * The typical usage of this widget is like this:

- * <programlisting>

- * static void

- * update_sensitivity_according_to_lock_button (FooBar *bar)

- * {

- * gboolean make_sensitive;

- *

- * make_sensitive = FALSE;

- * if (polkit_lock_button_get_is_authorized (POLKIT_LOCK_BUTTON (bar->priv->lock_button)))

- * {

- * make_sensitive = TRUE;

- * }

- * else

- * {

- * /<!-- -->* Catch the case where authorization is one-shot - this means

- * * an authentication dialog will be shown every time a widget the user

- * * manipulates calls into the Mechanism.

- * *<!-- -->/

- * if (polkit_lock_button_get_can_obtain (POLKIT_LOCK_BUTTON (bar->priv->lock_button)) &&

- * !polkit_lock_button_get_is_visible (POLKIT_LOCK_BUTTON (bar->priv->lock_button)))

- * make_sensitive = TRUE;

- * }

- *

- *

- * /<!-- -->* Make all widgets relying on authorization sensitive according to

- * * the value of make_sensitive.

- * *<!-- -->/

- * }

- *

- * static void

- * on_lock_button_changed (PolkitLockButton *button,

- * gpointer user_data)

- * {

- * FooBar *bar = FOO_BAR (user_data);

- *

- * update_sensitivity_according_to_lock_button (bar);

- * }

- *

- * static void

- * foo_bar_init (FooBar *bar)

- * {

- * /<!-- -->* Construct other widgets *<!-- -->/

- *

- * bar->priv->lock_button = polkit_lock_button_new ("org.project.mechanism.action-name");

- * g_signal_connect (bar->priv->lock_button,

- * "changed",

- * G_CALLBACK (on_lock_button_changed),

- * bar);

- * update_sensitity_according_to_lock_button (bar);

- *

- * /<!-- -->* Pack bar->priv->lock_button into widget hierarchy *<!-- -->/

- * }

- * </programlisting>
