Connect to GAuthorizeMethod signal.

Emitted when a method is invoked by a remote caller and used to determine if the method call is authorized.

Note that this signal is emitted in a thread dedicated to handling the method call so handlers are allowed to perform blocking IO. This means that it is appropriate to call e.g.

polkit_authority_check_authorization_sync()

with the

POLKIT_CHECK_AUTHORIZATION_FLAGS_ALLOW_USER_INTERACTION

flag set.

If false is returned then no further handlers are run and the signal handler must take a reference to invocation and finish handling the call (e.g. return an error via [gio.dbus_method_invocation.DBusMethodInvocation.returnError]).

Otherwise, if true is returned, signal emission continues. If no handlers return false, then the method is dispatched. If interface has an enclosing #GDBusObjectSkeleton, then the #GDBusObjectSkeleton::authorize-method signal handlers run before the handlers for this signal.

The default class handler just returns true.

Please note that the common case is optimized: if no signals handlers are connected and the default class handler isn't overridden (for both interface and the enclosing #GDBusObjectSkeleton, if any) and #GDBusInterfaceSkeleton:g-flags does not have the [gio.types.DBusInterfaceSkeletonFlags.HandleMethodInvocationsInThread] flags set, no dedicated thread is ever used and the call will be handled in the same thread as the object that interface belongs to was exported in.

Parameters

`callback`	signal callback delegate or function to connect `bool callback(gio.dbus_method_invocation.DBusMethodInvocation invocation, gio.dbus_interface_skeleton.DBusInterfaceSkeleton dBusInterfaceSkeleton)` `invocation` A #GDBusMethodInvocation. (optional) `dBusInterfaceSkeleton` the instance the signal is connected to (optional) `Returns` true if the call is authorized, false otherwise.
`after`	Yes.After to execute callback after default handler, No.After to execute before (default)

Returns

Signal ID
