"""Activity implementation code for Sugar-based activities
|
||||
|
||||
Each activity within the OLPC environment must provide two
|
||||
dbus services. The first, patterned after the
|
||||
|
||||
sugar.activity.activityfactory.ActivityFactory
|
||||
|
||||
class is responsible for providing a "create" method which
|
||||
takes a small dictionary with values corresponding to a
|
||||
|
||||
sugar.activity.activityhandle.ActivityHandle
|
||||
|
||||
describing an individual instance of the activity.
|
||||
|
||||
Each activity so registered is described by a
|
||||
|
||||
sugar.activity.bundle.Bundle
|
||||
|
||||
instance, which parses a specially formatted activity.info
|
||||
file (stored in the activity directory's ./activity
|
||||
subdirectory). The
|
||||
|
||||
sugar.activity.bundlebuilder
|
||||
|
||||
module provides facilities for the standard setup.py module
|
||||
which produces and registers bundles from activity source
|
||||
directories.
|
||||
|
||||
Once instantiated by the ActivityFactory's create method,
|
||||
each activity must provide an introspection API patterned
|
||||
after the
|
||||
|
||||
sugar.activity.activityservice.ActivityService
|
||||
|
||||
class. This class allows for querying the ID of the root
|
||||
window, requesting sharing across the network, and basic
|
||||
"what type of application are you" queries.

"""Base class for activities written in Python
|
||||
|
||||
This is currently the only definitive reference for what an
|
||||
activity must do to participate in the Sugar desktop.
|
||||
|
||||
A Basic Activity
|
||||
|
||||
All activities must implement a class derived from 'Activity' in this class.
|
||||
The convention is to call it ActivitynameActivity, but this is not required as
|
||||
the activity.info file associated with your activity will tell the sugar-shell
|
||||
which class to start.
|
||||
|
||||
For example the most minimal Activity:
|
||||
|
||||
|
||||
from sugar.activity import activity
|
||||
|
||||
class ReadActivity(activity.Activity):
|
||||
pass
|
||||
|
||||
To get a real, working activity, you will at least have to implement:
|
||||
__init__(), read_file() and write_file()
|
||||
|
||||
Aditionally, you will probably need a at least a Toolbar so you can have some
|
||||
interesting buttons for the user, like for example 'exit activity'
|
||||
|
||||
See the methods of the Activity class below for more information on what you
|
||||
will need for a real activity.

"""This is the base Activity class that all other Activities derive from.
|
||||
This is where your activity starts.
|
||||
|
||||
To get a working Activity:
|
||||
0. Derive your Activity from this class:
|
||||
class MyActivity(activity.Activity):
|
||||
...
|
||||
|
||||
1. implement an __init__() method for your Activity class.
|
||||
|
||||
Use your init method to create your own ActivityToolbar which will
|
||||
contain some standard buttons:
|
||||
toolbox = activity.ActivityToolbox(self)
|
||||
|
||||
Add extra Toolbars to your toolbox.
|
||||
|
||||
You should setup Activity sharing here too.
|
||||
|
||||
Finaly, your Activity may need some resources which you can claim
|
||||
here too.
|
||||
|
||||
The __init__() method is also used to make the distinction between
|
||||
being resumed from the Journal, or starting with a blank document.
|
||||
|
||||
2. Implement read_file() and write_file()
|
||||
Most activities revolve around creating and storing Journal entries.
|
||||
For example, Write: You create a document, it is saved to the Journal
|
||||
and then later you resume working on the document.
|
||||
|
||||
read_file() and write_file() will be called by sugar to tell your
|
||||
Activity that it should load or save the document the user is working
|
||||
on.
|
||||
|
||||
3. Implement our Activity Toolbars.
|
||||
The Toolbars are added to your Activity in step 1 (the toolbox), but
|
||||
you need to implement them somewhere. Now is a good time.
|
||||
|
||||
There are a number of standard Toolbars. The most basic one, the one
|
||||
your almost absolutely MUST have is the ActivityToolbar. Without
|
||||
this, you're not really making a proper Sugar Activity (which may be
|
||||
okay, but you should really stop and think about why not!) You do
|
||||
this with the ActivityToolbox(self) call in step 1.
|
||||
|
||||
Usually, you will also need the standard EditToolbar. This is the one
|
||||
which has the standard copy and paste buttons. You need to derive
|
||||
your own EditToolbar class from sugar.EditToolbar:
|
||||
class EditToolbar(activity.EditToolbar):
|
||||
...
|
||||
|
||||
See EditToolbar for the methods you should implement in your class.
|
||||
|
||||
Finaly, your Activity will very likely need some activity specific
|
||||
buttons and options you can create your own toolbars by deriving a
|
||||
class from gtk.Toolbar:
|
||||
class MySpecialToolbar(gtk.Toolbar):
|
||||
...
|
||||
|
||||
4. Use your creativity. Make your Activity something special and share
|
||||
it with your friends!
|
||||
|
||||
Read through the methods of the Activity class below, to learn more about
|
||||
how to make an Activity work.
|
||||
|
||||
Hint: A good and simple Activity to learn from is the Read activity. To
|
||||
create your own activity, you may want to copy it and use it as a template.

the file itself cannot be changed externally, but the title, description

notice changes, this is the time to record the originals.
