adesklet au premier plan

Salut,

j'aimerais placer un desklet adesklet au premier plan, c'est-à-dire au-dessus d'un panel gnome. Malheureusement, je ne vois pas comment faire...
Il semble que cette option ne soit pas dans les options générales de config des desklets, mais je suis prêt à trifouiller un peu le code du desklet en question pour l'adapter (je l'ai déjà adapté à ce que je souhaitais...)

Source du desklet en question :

#!/usr/bin/env python

This is a simple little desklet that displays a text-based digital clock.

The font, font size, font color, and time format are configurable.

The font color is specified as an HTML-style hexadecimal value, eg "#FFFFFF" for
white, "#00FF00" for green, etc.

The most useful formatting strings for the time display are:

    %H  Hour (24-hour clock) as a decimal number [00,23].
    %I  Hour (12-hour clock) as a decimal number [01,12].
    %M  Minute as a decimal number [00,59].
    %p  Locale's equivalent of either AM or PM.
    %S  Second as a decimal number [00,61].

Though the complete lineup of Python strformat() formatting strings is available
if you happen to want additional options.  For a complete list, refer to:
    
    http://docs.python.org/lib/module-time.html

Like the other demo adesklets packages, you can just run this script from its
final location on your disk to start it.

    This is the asimpleclock.py desklet configuration file.  Each instance of
    the desklet gets a separate Python dictionary that holds its 
    configuration.  You can adjust the font, font color, font size, and output
    format as you see fit.

    Valid fonts are:
        * Vera
        * Whatever you have installed
       
    Font color is an HTML-style hexadecimal number, eg "#FF0000" for red.

    Font size is a plain old integer.

    The format string can use any of the normal Python time formatting strings.

Re : adesklet au premier plan

passer un desklet au premier plan me serait très utile aussi, je m'étonne de ne trouver aucune aide sur internet (et pourtant je cherche (mal ?)) pour une action qui me parrait aussi indispensable !

Alors toutes les belles captures d'écran des magnifiques bureaux qu'on trouve , et où on apperçoit des jolies barres d'outils, sur ces bureaux la , les deklets ne pourraient pas se trouvaient au premier plan ? Les barres d'outils ne servent que lorsqu'aucune fenêtre n'est ouverte ? Je ne comprends pas !
