Detailed Description

When a notification is received it displays a pulsing icon, that is specified as part of the notification, at the top left corner of the screen. This icon stays in there for just a few seconds.

The received notification can be found at the activities tray. It is represented by a button with a notification badge.

The button's palette displays, at the bottom of the palette, all the notifications that are related to the same entity. Entities can be basically anything, ie., the journal, activities or even scripts running in background.

Every notification must belong to an entity. If one notification is sent, that notification should create a new icon if and only if there is not a previous icon for the same entity.

If one entity receives more than 5 notifications, scrolling will be used to limit the space.

Benefit to Sugar

This would be nice for chat, calenders, and any other kind of even that the user should be aware of. It would help bring us into line with the other desktop environs.

Scope

The current implementation covers all the building blocks that are required for journal, activities and system message notifications. At the moment, only system messages are implemented, using these same building blocks.

UI Design

http://wiki.sugarlabs.org/go/Design_Team/Proposals/Notifications

How To Test

For system notifications you can run this script, ie., from Terminal activity:

   import dbus
   BUS_NAME = 'org.freedesktop.Notifications'
   OBJ_PATH = '/org/freedesktop/Notifications'
   IFACE_NAME = 'org.freedesktop.Notifications'
   bus = dbus.SessionBus()
   notify_obj = bus.get_object(BUS_NAME,OBJ_PATH)
   notifications = dbus.Interface(notify_obj,IFACE_NAME)
   notifications.Notify("Software Update", 0, , "New activities are available!", "Please check your activities list", [], {'x-sugar-icon-name': 'module-updater'}, -1)

User Experience

These messages notifications should not distract the user, as they are displayed in each notification area.
