/**
* SECTION:messaging-menu
* @title: MessagingMenuApp
* @short_description: An application section in the messaging menu
* @include: messaging-menu.h
*
* A #MessagingMenuApp represents an application section in the
* Messaging Menu. An application section is tied to an installed
* application through a desktop file id, which must be passed to
* messaging_menu_app_new().
*
* To register the application with the Messaging Menu, call
* messaging_menu_app_register(). This signifies that the application
* should be present in the menu and be marked as "running".
*
* The first menu item in an application section represents the
* application itself, using the name and icon found in the associated
* desktop file. Activating this item starts the application.
*
* Following the application item, the Messaging Menu inserts all
* shortcut actions found in the desktop file. Actions whose
* NotShowIn keyword contains "Messaging Menu" or whose
* OnlyShowIn keyword does not contain "Messaging Menu"
* will not appear (the
* desktop file specification contains a detailed explanation of
* shortcut actions.) An application cannot add, remove, or change
* these shortcut items while it is running.
*
* Next, an application section contains menu items for message sources.
* What exactly constitutes a message source depends on the type of
* application: an email client's message sources are folders
* containing new messages, while those of a chat program are persons
* that have contacted the user.
*
* A message source is represented in the menu by a label and optionally
* also an icon. It can be associated with either a count, a time, or
* an arbitrary string, which will appear on the right side of the menu
* item.
*
* When the user activates a source, the source is immediately removed
* from the menu and the "activate-source" signal is emitted.
*
* Applications should always expose all the message sources available.
* However, the Messaging Menu might limit the amount of sources it
* displays to the user.
*
* The Messaging Menu offers users a way to set their chat status
* (available, away, busy, invisible, or offline) for multiple
* applications at once. Applications that appear in the Messaging Menu
* can integrate with this by setting the
* "X-MessagingMenu-UsesChatSection" key in their desktop file to True.
* Use messaging_menu_app_set_status() to signify that the application's
* chat status has changed. When the user changes status through the
* Messaging Menu, the ::status-changed signal will be emitted.
*
* If the application stops running without calling
* messaging_menu_app_unregister(), it will be marked as "not running".
* Its application and shortcut items stay in the menu, but all message
* sources are removed. If messaging_menu_app_unregister() is called,
* the application section is removed completely.
*
* More information about the design and recommended usage of the
* Messaging Menu is available at https://wiki.ubuntu.com/MessagingMenu.
