The #GApplication wraps some + * low-level platform-specific services; it's expected that most + * software will use a higher-level application class such as + * #GtkApplication or #MxApplication. + * + * In addition to single-instance-ness, #GApplication provides support + * for 'actions', which can be presented to the user in a platform-specific + * way (e.g. Windows 7 jump lists). Note that these are just simple actions + * without parameters. For more flexible scriptability, implementing a + * a separate D-Bus interface is recommended, see e.g. + * <xref linkend="gdbus-convenience"/>. + * + * 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>. + * Examples include: "com.example.MyApp" "org.example.internal-apps.Calculator" + * For convenience, the restrictions on application identifiers are reproduced + * here: + * <itemizedlist> + * <listitem>Application identifiers must contain only the ASCII characters "[A-Z][a-z][0-9]_-" and must not begin with a digit.</listitem> + * <listitem>Application identifiers must contain at least one '.'

The implementation + * exports an object at the object path that is created by replacing '.' with + * '/' in the application identifier (e.g. the object path for the + * application id 'org.gtk.TestApp' is '/org/gtk/TestApp').
