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.
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".
The application will be marked as "not running" as soon as app
is
destroyed. The application launcher as well as shortcut actions will
remain in the menu. To completely remove the application section
from the Messaging Menu, call messaging_menu_app_unregister().
void
messaging_menu_app_unregister (MessagingMenuApp *app);
Completely removes the app
from the Messaging Menu. If the
application's launcher and shortcut actions should remain in the
menu, destroying app
with g_object_unref() suffices.
Note: app
will remain valid and usable after this call.
void messaging_menu_app_set_status (MessagingMenuApp *app,MessagingMenuStatus status);
Notify the Messaging Menu that the chat status of app
has changed to
status
.
Connect to the ::status-changed signal to receive notification about the user changing their global chat status through the Messaging Menu.
This function does nothing for applications whose desktop file does not include X-MessagingMenu-UsesChatSection.
void messaging_menu_app_insert_source (MessagingMenuApp *app,gint position,const gchar *id,GIcon *icon,const gchar *label);
Inserts a new message source into the section representing app
. Equivalent
to calling messaging_menu_app_insert_source_with_time() with the current
time.
It is an error to insert a source with an id
which already exists. Use
messaging_menu_app_has_source() to find out whether there is such a source.
void messaging_menu_app_append_source (MessagingMenuApp *app,const gchar *id,GIcon *icon,const gchar *label);
Appends a new message source to the end of the section representing app
.
Equivalent to calling messaging_menu_app_append_source_with_time() with the
current time.
It is an error to add a source with an id
which already exists. Use
messaging_menu_app_has_source() to find out whether there is such a source.
void messaging_menu_app_insert_source_with_count (MessagingMenuApp *app,gint position,const gchar *id,GIcon *icon,const gchar *label,guint count);
Inserts a new message source into the section representing app
and
initializes it with count
.
To update the count, use messaging_menu_app_set_source_count().
It is an error to insert a source with an id
which already exists. Use
messaging_menu_app_has_source() to find out whether there is such a source.
void messaging_menu_app_append_source_with_count (MessagingMenuApp *app,const gchar *id,GIcon *icon,const gchar *label,guint count);
Appends a new message source to the end of the section representing app
and
initializes it with count
.
To update the count, use messaging_menu_app_set_source_count().
It is an error to add a source with an id
which already exists. Use
messaging_menu_app_has_source() to find out whether there is such a source.
void messaging_menu_app_insert_source_with_time (MessagingMenuApp *app,gint position,const gchar *id,GIcon *icon,const gchar *label,gint64 time);
Inserts a new message source into the section representing app
and
initializes it with time
. Use messaging_menu_app_insert_source() to
insert a source with the current time.
To change the time, use messaging_menu_app_set_source_time().
It is an error to insert a source with an id
which already exists. Use
messaging_menu_app_has_source() to find out whether there is such a source.
void messaging_menu_app_append_source_with_time (MessagingMenuApp *app,const gchar *id,GIcon *icon,const gchar *label,gint64 time);
Appends a new message source to the end of the section representing
app
and initializes it with time
. Use
messaging_menu_app_append_source() to append a source with the
current time.
To change the time, use messaging_menu_app_set_source_time().
It is an error to insert a source with an id
which already exists. Use
messaging_menu_app_has_source() to find out whether there is such a source.
void messaging_menu_app_append_source_with_string (MessagingMenuApp *app,const gchar *id,GIcon *icon,const gchar *label,const gchar *str);
Appends a new message source to the end of the section representing app
and
initializes it with str
.
To update the string, use messaging_menu_app_set_source_string().
It is an error to insert a source with an id
which already exists. Use
messaging_menu_app_has_source() to find out whether there is such a source.
void messaging_menu_app_insert_source_with_string (MessagingMenuApp *app,gint position,const gchar *id,GIcon *icon,const gchar *label,const gchar *str);
Inserts a new message source into the section representing app
and
initializes it with str
.

Removes the source corresponding to source_id
from the menu.
gboolean messaging_menu_app_has_source (MessagingMenuApp *app,const gchar *source_id);
void messaging_menu_app_set_source_label (MessagingMenuApp *app,const gchar *source_id,const gchar *label);
Changes the label of source_id
to label
.
void messaging_menu_app_set_source_icon (MessagingMenuApp *app,const gchar *source_id,GIcon *icon);

needs attention.
void messaging_menu_app_remove_attention (MessagingMenuApp *app,const gchar *source_id);
Stop indicating that source_id
needs attention.
This function does not need to be called when the source is removed
with messaging_menu_app_remove_source() or the user has activated the
source.
