"location-updated": (
    arg0: number,
    arg1: number,
    arg2: number,
    arg3: number,
    arg4: number,
    arg5: number,
    arg6: string,
    arg7: number,
    arg8: number,
) => void

Emitted when location monitoring is enabled and the location changes.

"notification-action-invoked": (
    arg0: string,
    arg1: string,
    arg2: GLib.Variant<any>,
) => void

Emitted when a non-exported action is activated on a notification.

"session-state-changed": (arg0: boolean, arg1: Xdp.LoginSessionState) => void

Emitted when session state monitoring is enabled and the state of the login session changes or the screensaver is activated or deactivated.

"spawn-exited": (arg0: number, arg1: number) => void

Emitted when a process that was spawned with Portal.spawn exits.

"update-available": (arg0: string, arg1: string, arg2: string) => void

Emitted when updates monitoring is enabled and a new update is available.

It is only sent once with the same information, but it can be sent many times if new updates appear.

"update-progress": (
    arg0: number,
    arg1: number,
    arg2: number,
    arg3: Xdp.UpdateStatus,
    arg4: string,
    arg5: string,
) => void

Emitted to indicate progress of an update installation.

It is undefined exactly how often it is sent, but it will be emitted at least once at the end with a non-zero status. For each successful operation in the update, we're also guaranteed to send exactly one signal with progress 100.

Properties - Inherited from GObject

notify: (arg0: GObject.ParamSpec) => void

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

Note that getting this signal doesn’t itself guarantee that the value of the property has actually changed. When it is emitted is determined by the derived GObject class. If the implementor did not create the property with GObject.ParamFlags.EXPLICIT_NOTIFY, then any call to g_object_set_property() results in ::notify being emitted, even if the new value is the same as the old. If they did pass GObject.ParamFlags.EXPLICIT_NOTIFY, then this signal is emitted only when they explicitly call g_object_notify() or g_object_notify_by_pspec(), and common practice is to do that only when the value has actually changed.

This signal is typically used to obtain change notification for a single property, by specifying the property name as a detail in the g_signal_connect() call, like this:

g_signal_connect (text_view->buffer, "notify::paste-target-list",
G_CALLBACK (gtk_text_view_target_list_notify),
text_view)

It is important to note that you must use [canonical parameter names][class@GObject.ParamSpec#parameter-names] as detail strings for the notify signal.
