Estou tentando escrever um ambiente de desktop que suporte o menu global Antes de começar a minha tarefa principal No PyQt, estou tentando fazer com que o código dbus funcione com QtDBus como prova de conceito. Aqui está a saída impressa e a assinatura do método que obtive de d-feet:
GetMenus() -> (Array of [Struct of (Uint32,String,Object Path)] menus)
[(60817412L, u':1.155', '/com/canonical/menu/3A00004'),
(58725289L, u':1.151', '/com/canonical/menu/38013A9'),
(58720393L, u':1.151', '/com/canonical/menu/3800089'),
(62916305L, u':1.159', '/com/canonical/menu/3C006D1'),
(54526127L, u':1.129', '/com/canonical/menu/34000AF'),
(58725701L, u':1.151', '/com/canonical/menu/3801545'),
(25167093L, u':1.22', '/com/canonical/menu/18004F5'),
(58726237L, u':1.151', '/com/canonical/menu/380175D'),
(60825279L, u':1.155', '/com/canonical/menu/3A01EBF'),
(58721371L, u':1.151', '/com/canonical/menu/380045B'),
(25165828L, u':1.22', '/com/canonical/menu/1800004')]
Este é o código que escrevi no PyQt esperando algo semelhante:
from PyQt4.QtGui import QApplication
from PyQt4.QtDBus import QDBus
from PyQt4.QtDBus import QDBusConnection
from PyQt4.QtDBus import QDBusInterface
desktop = QApplication([])
session_bus_connection = QDBusConnection.sessionBus()
service_name = 'com.canonical.AppMenu.Registrar'
service_path = 'com/canonical/AppMenu/Registrar'
interface = 'com.canonical.AppMenu.Registrar'
menu = QDBusInterface(service_name, service_path, interface, QDBusConnection.sessionBus())
reply = menu.call('GetMenus')
print reply.arguments()
desktop.exec_()
Esta é a saída que recebo do código acima:
christopher@xx-pc:~/Documents/Code$ python desktop_dbus.py

This is normally a bug in some application using the D-Bus library.

QDBusConnection: error: could not send message to service "com.canonical.AppMenu.Registrar" path "com/canonical/AppMenu/Registrar" interface "org.freedesktop.DBus.Introspectable" member "Introspect":

Alguém pode me dizer por que a mensagem não está sendo enviada?
