ah oki, je pense que le mieux c'est d'utiliser la méthode AddSubIcons, et de récupérer l'objet org.cairodock.CairoDock.subapplet, puis de l'utiliser comme l'objet org.cairodock.CairoDock.applet pour agir sur les icônes du sous-dock.

Bon toujours en train de m'amuser avec python et dbus j'aimerais comprendre comment faire pour executer une commade toutes les x secondes ou millisecondes...

Je voudrais donner l'impression d'un CD qui tourne sans faire perdre trop de CPU donc il me faut une boucle et puis j'ai pense a quatres images se repetant d'un CD a intervalle regulier cela pourrait donner l'impression de rotation...

Pour l'instant c'est a l'etat de test mais je pense qu'avec plein d'images de CD cette impression pourrait le faire en reduisant au max la conso CPU..

pour executer une commade toutes les x secondes ou millisecondes...

tu utilises un g_timeout (une fonction de la GLib, la syntaxe exacte en python je ne sais pas

)

toujours dans ma recherche sur python je suis sur du code que je comprends pas du moins que j'arrive pas a faire marcher...

..

J'ai retrouve la version de spectrolet en python pure donc on a pas besoin de screenlet pour l'installer mais celle-ci n'est plus supporte par la version de python il me dit que

/home/taiebot/Bureau/Spectrolet-0.1a1-r10/Spectrolet.py:210: DeprecationWarning: os.popen3 is deprecated. Use the subprocess module.
audio_stream = os.popen3( "pacat -r -d %s" % device )

donc avec le code suivant

    for stream in audio_stream:
        stream.close( )

parce que os.popen() et os.popen3() ne sont plus supportes .. donc faudrait les remplacer par

http://docs.python.org/library/subprocess.html#subprocess-replacements

moi je suis paume mais ca serait un bon debut pour avoir un spectre de musique dans le dock...si quelqu'un pouvait m'aider..

Ben deja il faut importer le module subprocess

from subprocess import Popen

subprocess apparement contient un class Popen qui te permet de remplacer entre autre popen et popen3

os.popen( "pactl list | grep monitor" )

deviendrait

Popen("pactl list | grep monitor", shell=True)

par contre pour le reste tu va devoir bidouiller un peu car Popen ne connait pas readline

sinon quel version de Python tu utilises?

comment ca hors de porte?

je ne comprends pas ce que tu veux dire?

Voila ce que ca donne dans un CLI de python.

>>>import subprocess
>>> subprocess.Popen("pactl list | grep monitor", shell=True)
<subprocess.Popen object at 0x7f4b15a3fcd0>
>>> Monitor Source: alsa_output.pci-0000_00_07.0.analog-stereo.monitor
Name: alsa_output.pci-0000_00_07.0.analog-stereo.monitor
device.class = "monitor"

ce n'est pas complique ensuite d'extraire la ligne qui t'interresse....j'essaierais ce soir et je te tiens au courant.

Le probleme c'est qu'il y a l'autre aussi...

device = os.popen( "pactl list | grep monitor" ).readline( ).strip( )[len( "Name: " ):]

audio_stream = os.popen3( "pacat -r -d %s" % device )

si je comprends bien il trouve bien tout mais apres je sais pas quoi en faire il faut que os.popen3 reconnaisse aussi pactL
