## D-Bus D-Bus — The D-Bus Services |

## Types and Values

#define | CAJA_ACTIONS_DBUS_SERVICE

## Includes

    #include <caja-actions/na-dbus.h>

## Description

Caja-Actions™, through its tracker plugin, exposes several D-Bus interfaces. These interfaces may be queried in order to get information about current selection, Caja-Actions™ status, and so on.

To be really clear, Caja-Actions™ relies on Caja™ in order to be able to register its own D-Bus services via the tracker plugin.

If Caja™ does not run, or the tracker plugin is not loaded at Caja™ startup, then these D-Bus services will not be available.

## Functions

## Types and Values

### CAJA_ACTIONS_DBUS_SERVICE

    #define CAJA_ACTIONS_DBUS_SERVICE            "org.caja-actions.DBus"

This is the « well-known » name that Caja-Actions™ reserves on D-Bus session bus.

### CAJA_ACTIONS_DBUS_TRACKER_PATH

    #define CAJA_ACTIONS_DBUS_TRACKER_PATH       "/org/caja_actions/DBus/Tracker"

The D-Bus path of the tracker object.

When requested through the `Introspect` of the

`Introspectable` D-Bus interface, the

tracker object returns following information:

        dbus-send \
          --session \
          --type=method_call \
          --print-reply \
          --dest=org.caja-actions.DBus \
            /org/caja_actions/DBus/Tracker \
              org.freedesktop.DBus.Introspectable.Introspect

### CAJA_ACTIONS_DBUS_TRACKER_IFACE

    #define CAJA_ACTIONS_DBUS_TRACKER_IFACE  	"org.caja_actions.DBus.Tracker.Properties1"

An interface defined on the tracker object, identified by its `CAJA_ACTIONS_DBUS_TRACKER_PATH` D-Bus path.
