It wraps some -low-level platform-specific services and is intended to act as the -foundation for higher-level application classes such as -<a href="http://developer.gnome.org/devel/gtk/GtkApplication.html"><span class="type">GtkApplication</span></a> or <span class="type">MxApplication</span>. In general, you should not use -this class outside of a higher level framework. -</p> -<p> -GApplication provides convenient life cycle management by maintaining -a <em class="firstterm">use count</em> for the primary application instance. -The use count can be changed using <a class="link" href="GApplication.html#g-application-hold" title="g_application_hold ()"><code class="function">g_application_hold()</code></a> and -<a class="link" href="GApplication.html#g-application-release" title="g_application_release ()"><code class="function">g_application_release()</code></a>. If it drops to zero, the application exits. -Higher-level classes such as <a href="http://developer.gnome.org/devel/gtk/GtkApplication.html"><span class="type">GtkApplication</span></a> employ the use count to -ensure that the application stays alive as long as it has any opened -windows. -</p> -<p> -Another feature that GApplication (optionally) provides is process -uniqueness. Applications can make use of this functionality by -providing a unique application ID. If given, only one application -with this ID can be running at a time per session. The session -concept is platform-dependent, but corresponds roughly to a graphical -desktop login. When your application is launched again, its -arguments are passed through platform communication to the already -running program. The already running instance of the program is -called the <em class="firstterm">primary instance</em>; for non-unique -applications this is the always the current instance. -On Linux, the D-Bus session bus is used for communication. -</p> -<p> -If used, the expected form of an application identifier is very close -to that of of a -<a class="ulink" href="http://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-names-interface" target="_top">DBus bus name</a>. -Examples include: "com.example.MyApp", "org.example.internal-apps.Calculator". -For details on valid application identifiers, see <a class="link" href="GApplication.html#g-application-id-is-valid" title="g_application_id_is_valid ()"><code class="function">g_application_id_is_valid()</code></a>. -</p> -<p> -On Linux, the application identifier is claimed as a well-known bus name -on the user's session bus. This means that the uniqueness of your -application is scoped to the current session. It also means that your -application may provide additional services (through registration of other -object paths) at that bus name. The registration of these object paths -should be done with the shared GDBus session bus. Note that due to the -internal architecture of GDBus, method calls can be dispatched at any time -(even if a main loop is not running). For this reason, you must ensure that -any object paths that you wish to register are registered before <a class="link" href="GApplication.html" title="GApplication"><span class="type">GApplication</span></a> -attempts to acquire the bus name of your application (which happens in -<a class="link" href="GApplication.html#g-application-register" title="g_application_register ()"><code class="function">g_application_register()</code></a>). Unfortunately, this means that you cannot use -<a class="link" href="GApplication.html#g-application-get-is-remote" title="g_application_get_is_remote ()"><code class="function">g_application_get_is_remote()</code></a> to decide if you want to register object paths. -</p> -<p> -GApplication also implements the <a class="link" href="GActionGroup.html" title="GActionGroup"><span class="type">GActionGroup</span></a> and <a class="link" href="GActionMap.html" title="GActionMap"><span class="type">GActionMap</span></a> -interfaces and lets you easily export actions by adding them with -<a class="link" href="GActionMap.html#g-action-map-add-action" title="g_action_map_add_action ()"><code class="function">g_action_map_add_action()</code></a>.

The actions are also exported on -the session bus, and GIO provides the <a class="link" href="GDBusActionGroup.html" title="GDBusActionGroup"><span class="type">GDBusActionGroup</span></a> wrapper to -conveniently access them remotely.
