      org.freedesktop.GeoClue2.Client:
      @short_description: The Application-specific client API

      This is the interface you use to retrieve location information and receive
      location update signals from GeoClue service. You get the client object to
      use this interface on from
      <link linkend="gdbus-method-org-freedesktop-GeoClue2-Manager.GetClient">
      org.freedesktop.GeoClue2.Manager.GetClient()</link> method.

  <interface name="org.freedesktop.GeoClue2.Client">
    <!--
        Location:

        Current location as path to a
        <link linkend="gdbus-org.freedesktop.GeoClue2.Location">
        org.freedesktop.GeoClue2.Location</link> object. Please note that this
        property will be set to "/" (D-Bus equivalent of null) initially, until
        Geoclue finds user's location. You want to delay reading this property
        until your callback to #org.freedesktop.GeoClue2.Client::LocationUpdated
        signal is called for the first time after starting the client.

    <property name="Location" type="o" access="read"/>

    <!--
        DistanceThreshold:

        Contains the current distance threshold in meters. This value is used
        by the service when it gets new location info. If the distance moved is
        below the threshold, it won't emit the LocationUpdated signal.
        The default value is 0. When DistanceThreshold is zero, it always emits
        the signal.

    <!--
        TimeThreshold:

        Contains the current time threshold in seconds. This value is used
        by the service when it gets new location info. If the time since the
        last update is below the threshold, it won't emit the LocationUpdated
        signal. The default value is 0. When TimeThreshold is zero, it always
        emits the signal.

        DesktopId:

        The desktop file id (the basename of the desktop file). This property
        must be set by applications for authorization to work.

    <property name="DesktopId" type="s" access="readwrite"/>

    <!--
        RequestedAccuracyLevel:

        The level of accuracy requested by client, as
        <link linkend="GClueAccuracyLevel">GClueAccuracyLevel</link>.

        Please keep in mind that the actual accuracy of location information is
        dependent on available hardware on your machine, external resources
        and/or how much accuracy user agrees to be confortable with.
    -->
    <property name="RequestedAccuracyLevel" type="u" access="readwrite"/>

    <!--
        Active:

        If client is active, i-e started successfully using
        org.freedesktop.GeoClue2.Client.Start() and receiving location updates.

        Please keep in mind that geoclue can at any time stop and start the
        client on user (agent) request. Applications that are interested in
        in these changes, should watch for changes in this property.

    <!--
        Start:

        Start receiving events about the current location. Applications should
        hook-up to #org.freedesktop.GeoClue2.Client::LocationUpdated signal
        before calling this method.
    -->
    <method name="Start"/>

    <!--
        Stop:

        Stop receiving events about the current location.

        LocationUpdated:
        @old: old location as path to a #org.freedesktop.GeoClue2.Location object
        @new: new location as path to a #org.freedesktop.GeoClue2.Location object

        The signal is emitted every time the location changes.
        The client should set the DistanceThreshold property to control how
        often this signal is emitted.
