Description

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.

Functions

messaging_menu_app_append_source ()

messaging_menu_app_register ()

void
messaging_menu_app_register (MessagingMenuApp *app);

Registers app with the Messaging Menu.

If the application doesn't already have a section in the Messaging Menu, one will be created for it. The application will also be marked as "running".
