pypanel volume control

not long ago i tried to use xfce4, and i really disliked that thunar depends on gnome libs for some stuff.
so i started to think about moving to another DE or even WM.
i wanted really fast and light one.
so now i'm trying OpenBox.

it doesn't have own panel, so i use pypanel.
the only thing i dislike about it is the lack of volume control.

so i wrote my own.
here's the patch against pypanel-2.4: http://wakeroid.googlepages.com/pypanel-volume.diff

and you'll need to add this to .pypanelrc:

VOLUME = N # where N is volume control position, 0 to disable
import alsaaudio;
mixer = alsaaudio.Mixer('PCM')

def volumeButtonEvent (pp, button):
 if button == 4:
     mixvolume = mixer.getvolume()[0]
     mixvolume += 5
     if mixvolume > 100:
         mixvolume = 100
     mixer.setvolume (mixvolume)
 elif button == 5:
     mixvolume = mixer.getvolume()[0]
     mixvolume -= 5
     if mixvolume < 0:
         mixvolume = 0
     mixer.setvolume (mixvolume)
