Gtk 3, python, appindicator, icône de désactivation près de l'étiquette

Question

J'écris openindows appindicator de site en python, mais je n'ai besoin que d'étiquette de texte dans l'indicateur sans icône. Mais quand je pars "" alors montrez-moi l'icône vide. Pourquoi, j'ai seulement besoin de texte. Dans Ubuntu 12.04, python-appindicator n'a pas besoin d'une icône si vous laissez "" alors ne pas charger une icône vide, mais dans Ubuntu 14.04, laissez l'icône vide. Comment désactiver l'icône? Des idées?

La seule façon que j'ai trouvé est d'utiliser soit votre propre icône mince invisible ou d'utiliser une ubuntu existante fine et subtile, comme .png ou /usr/share/unity/icons/panel-shadow.png Vous pouvez implémenter un peu des deux:

icon_image = os.path.dirname(__file__) + "/my_thin_inv_icon.png" 
if not os.path.isfile(icon_image): 
    icon_image = "/usr/share/unity/icons/panel-shadow.png" 

self.ind = appindicator.Indicator.new("Weather",icon_image,appindicator.IndicatorCategory.APPLICATION_STATUS)
