Features/Messages Notification

Summary

The current icons-only notification system is generally ineffective to fully communicate different kind of system events. This feature provides a set of extensions to the current system to display simple text messages.

This feature will be use for special events and communications, it is not intended to replace the current logging system and Log activity viewer.

Detailed Description

Extends our support for the fd.o Desktop Notifications protocol

This feature requires a some re-factoring of jarabe.frame.notification(NotificationIcon, NotificationWindow) widgets.

Also, requires minimal extensions to jarabe.frame.frame(Frame) to extract the notification text message details.

Plus, since the corner notifications icons can't be seen for long periods of time (to avoid visual spam), a new tray bar can be added to the left side of the bottom frame window. This tray will contain current session's notifications.

Benefit to Sugar

Messages notification capabilities, useful in many different scenarios.

Scope

UI Design

Notification icons show up as usual, when clicking on icons a palette will show up with summary and body information. A new horizontal tray is added in the left side of the bottom frame, this works as a historical registry of current session notifications.

How To Test

Running this python script should work (provided by Gonzalo Odiard):

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("HelloWorld",0,'',"Summary","Body",[],{},-1)

Internet-Links in Notifications

This would help in navigating ta any internet-link, by simply clicking on the link.
There are two cases possible
- No instance of "Browse" is open. In this case, following sequence of steps happen ::
  - User clicks on the link in the notification.
  - "Browse" opens (in a new window, obviously) and the URL is loaded.
- There is an instance of "Browse" already open. In this case,
  - User clicks on the link.
  - The window gets switched to the "Browse" window (if not already).
  - The URL is loaded.
