Je travaille généralement sur un système Linux, mais j'ai une situation où j'ai besoin d'écrire une application client qui s'exécuterait sur Windows en tant que service. Quelqu'un peut-il m'aider ou diriger vers, sur la façon de créer une application MenuBar (par exemple comme dropbox) pour l'environnement Windows, qui démarre au démarrage du système d'exploitation et l'icône se trouve dans la barre des tâches et en cliquant sur l'icône de l'application présente un menu.
Mon langage de script est python. Merci.
Pour ce faire, utilisez le module pywin32 (Python for Windows Extensions) .
Pour le faire fonctionner au démarrage, vous pouvez jouer avec les services, mais il est en fait beaucoup plus facile d'installer un lien vers l'exe dans le "dossier de démarrage" des utilisateurs.

Il y a (au moins) quelques bibliothèques ouvertement disponibles pour cela maintenant:
Je viens de commencer à utiliser infi.systray
dans un projet, et ça a bien marché pour moi. Voici le peu de code dont vous avez besoin pour faire quelque chose de très basique (tiré de leurs documents):
from infi.systray import SysTrayIcon
def say_hello(systray):
print("Hello, World!")
menu_options = (("Say Hello", None, say_hello),)
systray = SysTrayIcon("icon.ico", "Example tray icon", menu_options)
systray.start()
