* @title: GApplication
* @short_description: Core application class
+ * @include: gio/gio.h
*
- * A #GApplication is the foundation of an application, unique for a
- * given application identifier. The GApplication class wraps some
+ * A #GApplication is the foundation of an application. It wraps some
* low-level platform-specific services and is intended to act as the
* foundation for higher-level application classes such as
* #GtkApplication or #MxApplication. In general, you should not use
* this class outside of a higher level framework.
*
- * One of the core features that GApplication provides is process
- * uniqueness, in the context of a "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
- * <firstterm>primary instance</firstterm>.
- *
- * Before using GApplication, you must choose an "application identifier".
- * The expected form of an application identifier is very close to that of
- * of a <ulink url="http://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-names-interface">DBus bus name</ulink>.
+ * GApplication provides convenient life cycle management by maintaining
+ * a "use count" for the primary application instance. The use count can
+ * be changed using g_application_hold() and g_application_release(). If
+ * it drops to zero, the application exits. Higher-level classes such as
+ * #GtkApplication employ the use count to ensure that the application
+ * stays alive as long as it has any opened windows.
+ *
+ * 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 "primary instance"; for non-unique applications this is
+ * the always the current instance. On Linux, the D-Bus session bus
+ * is used for communication.
+ *
+ * The use of #GApplication differs from some other commonly-used
+ * uniqueness libraries (such as libunique) in important ways. The
+ * application is not expected to manually register itself and check
+ * if it is the primary instance. Instead, the main() function of a
+ * #GApplication should do very little more than instantiating the
+ * application instance, possibly connecting signal handlers, then
+ * calling g_application_run(). All checks for uniqueness are done
+ * internally. If the application is the primary instance then the
+ * startup signal is emitted and the mainloop runs. If the application
+ * is not the primary instance then a signal is sent to the primary
+ * instance and g_application_run() promptly returns. See the code
+ * examples below.
+ *
+ * If used, the expected form of an application identifier is very close
+ * to that of of a
+ * [DBus bus name](http://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-names-interface).
* Examples include: "com.example.MyApp", "org.example.internal-apps.Calculator".
- * For details on valid application identifiers, see
- * g_application_id_is_valid().
+ * For details on valid application identifiers, see g_application_id_is_valid().
*
- * The application identifier is claimed by the application 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
- * #GApplication attempts to acquire the bus name of your application
- * (which happens in g_application_register()). Unfortunately, this
- * means that you can not use g_application_get_is_remote() to decide if
- * you want to register object paths.

+ *
+ * GApplication also implements the #GActionGroup and #GActionMap
+ * interfaces and lets you easily export actions by adding them with
+ * g_action_map_add_action(). When invoking an action by calling
+ * g_action_group_activate_action() on the application, it is always
+ * invoked in the primary instance. The actions are also exported on
+ * the session bus, and GIO provides the #GDBusActionGroup wrapper to
+ * conveniently access them remotely. GIO provides a #GDBusMenuModel wrapper
+ * for remote access to exported #GMenuModels.
+ *
+ * There is a number of different entry points into a GApplication:
+ *
+ * - via 'Activate' (i.e. just starting the application)
+ *
+ * - via 'Open' (i.e. opening some files)
+ *
+ * - by handling a command-line
+ *
+ * - via activating an action
*
- * GApplication provides convenient life cycle management by maintaining
- * a <firstterm>use count</firstterm> for the primary application instance.
- * The use count can be changed using g_application_hold() and
- * g_application_release(). If it drops to zero, the application exits.
- *
- * GApplication also implements the #GActionGroup interface and lets you
- * easily export actions by adding them with g_application_set_action_group().
- * When invoking an action by calling g_action_group_activate_action() on
- * the application, it is always invoked in the primary instance.
- *
- * There is a number of different entry points into a #GApplication:
- * <itemizedlist>
- * <listitem>via 'Activate' (i.e. just starting the application)</listitem>
- * <listitem>via 'Open' (i.e. opening some files)</listitem>
- * <listitem>by handling a command-line</listitem>
- * <listitem>via activating an action</listitem>
- * </itemizedlist>
* The #GApplication::startup signal lets you handle the application
* initialization for all of these in a single place.
*
- * Regardless of which of these entry points is used to start the application,
- * GApplication passes some <firstterm id="platform-data">platform
- * data</firstterm> from the launching instance to the primary instance,
- * in the form of a #GVariant dictionary mapping strings to variants.
- * To use platform data, override the @before_emit or @after_emit virtual
- * functions in your #GApplication subclass. When dealing with
- * #GApplicationCommandline objects, the platform data is directly

+/**
+ * GApplicationClass:
+ * @startup: invoked on the primary instance immediately after registration
+ * @shutdown: invoked only on the registered primary instance immediately
+ * after the main loop terminates
+ * @activate: invoked on the primary instance when an activation occurs
+ * @open: invoked on the primary instance when there are files to open
+ * @command_line: invoked on the primary instance when a command-line is
+ * not handled locally
+ * @local_command_line: invoked (locally) when the process has been invoked
+ * via commandline execution (as opposed to, say, D-Bus activation - which
+ * is not currently supported by GApplication). The virtual function has
+ * the chance to inspect (and possibly replace) the list of command line
+ * arguments. See g_application_run() for more information.
+ * @before_emit: invoked on the primary instance before 'activate', 'open',
+ * 'command-line' or any action invocation, gets the 'platform data' from
+ * the calling instance
+ * @after_emit: invoked on the primary instance after 'activate', 'open',
+ * 'command-line' or any action invocation, gets the 'platform data' from
+ * the calling instance
+ * @add_platform_data: invoked (locally) to add 'platform data' to be sent to
+ * the primary instance when activating, opening or invoking actions
+ * @quit_mainloop: Used to be invoked on the primary instance when the use
+ * count of the application drops to zero (and after any inactivity
+ * timeout, if requested). Not used anymore since 2.32
+ * @run_mainloop: Used to be invoked on the primary instance from
+ * g_application_run() if the use-count is non-zero. Since 2.32,
+ * GApplication is iterating the main context directly and is not
+ * using @run_mainloop anymore
+ * @dbus_register: invoked locally during registration, if the application is
+ * using its D-Bus backend. You can use this to export extra objects on the
+ * bus, that need to exist before the application tries to own the bus name.
+ * The function is passed the #GDBusConnection to to session bus, and the
+ * object path that #GApplication will use to export is D-Bus API.
+ * If this function returns %TRUE, registration will proceed; otherwise
+ * registration will abort. Since: 2.34
+ * @dbus_unregister: invoked locally during unregistration, if the application
+ * is using its D-Bus backend. Use this to undo anything done by the
+ * @dbus_register vfunc. Since: 2.34

+ * point, the application can inspect the values pointed to by @arg_data
+ * in the given #GOptionEntrys.
+ *
+ * Unlike #GOptionContext, #GApplication supports giving a %NULL
+ * @arg_data for a non-callback #GOptionEntry. This results in the
+ * argument in question being packed into a #GVariantDict which is also
+ * passed to #GApplication::handle-local-options, where it can be
+ * inspected and modified. If %G_APPLICATION_HANDLES_COMMAND_LINE is
+ * set, then the resulting dictionary is sent to the primary instance,
+ * where g_application_command_line_get_options_dict() will return it.
+ * This "packing" is done according to the type of the argument --
+ * booleans for normal flags, strings for strings, bytestrings for
+ * filenames, etc. The packing only occurs if the flag is given (ie: we
+ * do not pack a "false" #GVariant in the case that a flag is missing).
+ *
+ * In general, it is recommended that all commandline arguments are
+ * parsed locally. The options dictionary should then be used to
+ * transmit the result of the parsing to the primary instance, where
+ * g_variant_dict_lookup() can be used. For local options, it is
+ * possible to either use @arg_data in the usual way, or to consult (and
+ * potentially remove) the option from the options dictionary.
+ *
+ * This function is new in GLib 2.40. Before then, the only real choice
+ * was to send all of the commandline arguments (options and all) to the
+ * primary instance for handling. #GApplication ignored them completely
+ * on the local side. Calling this function "opts in" to the new
+ * behaviour, and in particular, means that unrecognised options will be
+ * treated as errors. Unrecognised options have never been ignored when
+ * %G_APPLICATION_HANDLES_COMMAND_LINE is unset.
+ *
+ * If #GApplication::handle-local-options needs to see the list of
+ * filenames, then the use of %G_OPTION_REMAINING is recommended. If
+ * @arg_data is %NULL then %G_OPTION_REMAINING can be used as a key into
+ * the options dictionary. If you do use %G_OPTION_REMAINING then you
+ * need to handle these arguments for yourself because once they are
+ * consumed, they will no longer be visible to the default handling
+ * (which treats them as filenames to be opened).

* to pass %NULL if @argv is not available or commandline handling is not
- * required.
- *
- * First, the local_command_line() virtual function is invoked.
- * This function always runs on the local instance. It gets passed a pointer
- * to a %NULL-terminated copy of @argv and is expected to remove the arguments
- * that it handled (shifting up remaining arguments). See
- * <xref linkend="gapplication-example-cmdline2"/> for an example of
- * parsing @argv manually. Alternatively, you may use the #GOptionContext API,
- * after setting <literal>argc = g_strv_length (argv);</literal>.
- *
- * The last argument to local_command_line() is a pointer to the @status
- * variable which can used to set the exit status that is returned from
- * g_application_run().
- *
- * If local_command_line() returns %TRUE, the command line is expected
- * to be completely handled, including possibly registering as the primary
- * instance, calling g_application_activate() or g_application_open(), etc.
- *
- * If local_command_line() returns %FALSE then the application is registered
- * and the #GApplication::command-line signal is emitted in the primary
- * instance (which may or may not be this instance). The signal handler
- * gets passed a #GApplicationCommandline object that (among other things)
- * contains the remaining commandline arguments that have not been handled
- * by local_command_line().
- *
- * If the application has the %G_APPLICATION_HANDLES_COMMAND_LINE
- * flag set then the default implementation of local_command_line()
- * always returns %FALSE immediately, resulting in the commandline
- * always being handled in the primary instance.
- *
- * Otherwise, the default implementation of local_command_line() tries
- * to do a couple of things that are probably reasonable for most
- * applications. First, g_application_register() is called to attempt
- * to register the application. If that works, then the command line
- * arguments are inspected. If no commandline arguments are given, then
- * g_application_activate() is called. If commandline arguments are
- * given and the %G_APPLICATION_HANDLES_OPEN flag is set then they
- * are assumed to be filenames and g_application_open() is called.
- *
- * If you need to handle commandline arguments that are not filenames,
- * and you don't mind commandline handling to happen in the primary
- * instance, you should set %G_APPLICATION_HANDLED_COMMAND_LINE and
- * process the commandline arguments in your #GApplication::command-line
- * signal handler, either manually or using the #GOptionContext API.
+ * required. Note that on Windows, @argc and @argv are ignored, and
+ * g_win32_get_command_line() is called internally (for proper support
+ * of Unicode commandline arguments).
+ *
+ * #GApplication will attempt to parse the commandline arguments. You
+ * can add commandline flags to the list of recognised options by way of
+ * g_application_add_main_option_entries(). After this, the
+ * #GApplication::handle-local-options signal is emitted, from which the
+ * application can inspect the values of its #GOptionEntrys.
+ *
+ * #GApplication::handle-local-options is a good place to handle options
+ * such as `--version`, where an immediate reply from the local process is
+ * desired (instead of communicating with an already-running instance).
+ * A #GApplication::handle-local-options handler can stop further processing
+ * by returning a non-negative value, which then becomes the exit status of
+ * the process.
+ *
+ * What happens next depends on the flags: if
+ * %G_APPLICATION_HANDLES_COMMAND_LINE was specified then the remaining
+ * commandline arguments are sent to the primary instance, where a
+ * #GApplication::command-line signal is emitted. Otherwise, the
+ * remaining commandline arguments are assumed to be a list of files.
+ * If there are no files listed, the application is activated via the
+ * #GApplication::activate signal. If there are one or more files, and
+ * %G_APPLICATION_HANDLES_OPEN was specified then the files are opened
+ * via the #GApplication::open signal.
*
* If you are interested in doing more complicated local handling of the
* commandline then you should implement your own #GApplication subclass
* and override local_command_line(). In this case, you most likely want
* to return %TRUE from your local_command_line() implementation to
* suppress the default handling. See
- * <xref linkend="gapplication-example-cmdline2"/> for an example.
+ * [gapplication-example-cmdline2.c][gapplication-example-cmdline2]
+ * for an example.
*
* If, after the above is done, the use count of the application is zero
* then the exit status is returned immediately. If the use count is
- * non-zero then the mainloop is run until the use count falls to zero,
- * at which point 0 is returned.
- *
- * If the %G_APPLICATION_IS_SERVICE flag is set, then the exiting at
- * use count of zero is delayed for a while (ie: the instance stays
- * around to provide its <emphasis>service</emphasis> to others).
+ * non-zero then the default main context is iterated until the use count
+ * falls to zero, at which point 0 is returned.
+ *
+ * If the %G_APPLICATION_IS_SERVICE flag is set, then the service will
+ * run for as much as 10 seconds with a use count of zero while waiting
+ * for the message that caused the activation to arrive. After that,
+ * if the use count falls to zero the application will exit immediately,
+ * except in the case that g_application_set_inactivity_timeout() is in
+ * use.
+ *
+ * This function sets the prgname (g_set_prgname()), if not already set,
+ * to the basename of argv[0]. Since 2.38, if %G_APPLICATION_IS_SERVICE
+ * is specified, the prgname is set to the application ID. The main
+ * impact of this is is that the wmclass of windows created by Gtk+ will
+ * be set accordingly, which helps the window manager determine which
+ * application is showing the window.
+ *
+ * Since 2.40, applications that are not explicitly flagged as services
+ * or launchers (ie: neither %G_APPLICATION_IS_SERVICE or
+ * %G_APPLICATION_IS_LAUNCHER are given as flags) will check (from the
+ * default handler for local_command_line) if "--gapplication-service"
+ * was given in the command line. If this flag is present then normal
+ * commandline processing is interrupted and the
+ * %G_APPLICATION_IS_SERVICE flag is set. This provides a "compromise"
+ * solution whereby running an application directly from the commandline
+ * will invoke it in the normal way (which can be useful for debugging)
+ * while still allowing applications to be D-Bus activated in service
+ * mode. The D-Bus service file should invoke the executable with
+ * "--gapplication-service" as the sole commandline argument. This
+ * approach is suitable for use by most graphical applications but
+ * should not be used from applications like editors that need precise
+ * control over when processes invoked via the commandline will exit and
+ * what their exit status will be.
