Re : adesklet: Calendar et transparence [resolu]

c est bon j ai reussi en modifiant le script Calenda.py

#!/usr/bin/env python
"""
Calendar.py - darkliquid <darkliquid@darkliquid.co.uk>, 2005

Simple, adesklets calendar script:
Basically, this should simply grab the output
of the calendar.month() function and display
on the screen using the fonts defined from the
config file. Eventually, I plan to add more
functionality to this so that different fonts
for various parts can be altered and then who knows?
