Tichy is a python applets manager for embedded devices.
The goal of the project is to make it easy to write many kind of applications for openmoko using the python language.
Tichy provides the following things :
- Graphics User Interface widgets
- Services registering and Requesting (for example an application that wants to send a message will request for an application implementing the message sending service)
- Tasklets system (This allow to write callback waiting process as if they were threads)
- Abstraction of Item / View
- A plug in system that make it easy to add new functionalities / applets to tichy
How to write an applets / plug-ins for tichy ?
Unfortunately There is currently no documentation.
Fortunately it is very easy to do. If you want to write a new applet, you just need to create a new directory in tichy/test/plugins/apps/. You can have a look at the other plug-ins to get an idea of how to do it. A basic app look like this :
import tichy import tichy.gui as gui import tichy.item as item from tichy.application import Application class MyApp(Application): name = "My Application" icon = 'icon.png' # to be found in the app directory def run(self, parent): w = gui.Window(parent, modal = True) # We run into a new modal window # Create a new frame with a "back" button on top frame = gui.ApplicationFrame(w, self, back_button=True) # This box is used to store the widgets box = gui.Box(frame, axis=1) # Create a text item text = item.Text('click to edit', editable = True) # Put a view of the item on the screen text.view(box) # Add a button button = gui.Button(box) gui.Label(button, "click me") def on_click(b): # "yield" means "block until the tasklet returns" yield gui.Message(w, you just clicked the button) button.connect('clicked', on_click) yield Wait(frame, 'back') # Wait until the back button is clicked w.close() # Don't forget to close the window

The sources can be found from svn repository on project.openmoko :
svn checkout svn://svn.projects.openmoko.org/svnroot/tichy
Running on the desktop
Thanks to the service system, that allows to provide several version of the same service, Tichy can run as well on a desktop computer as on the neo. When run on a desktop, tichy will simulate phone functionalities, when run on the neo, it will use the Framework.
To run it on the desktop, make sure you have python-pygames installed
sudo apt-get install python-pygame
Then just download the sources, then go into test, and run
Running on neo
You will need to compile some files, see the README for more information on how to do it.
You need python 2.5 and some libraries installed :
A package is available for it in Openmoko Testing and unstable feed. Unfortunately tichy won't work yet, because of a bug in python-pygame in openmoko feeds.
