Dbus 개체 내보내기

Question

왜 개체 내보내기가 실행되지 않습니까?

Answer 1

오류가 메인 루프를 설정하는 중입니다. 방금 GLib.MainLoop 전달하는 동안

if __name__ == '__main__': 
    from gi.repository import GLib 
    loop = GLib.MainLoop() 
    glib_main(set_as_default = True) 
    conn = DBus.SessionBus(mainloop = loop) # <**offending line**> 
    Notifier(conn, "org.freedesktop.Notifications") 
    loop.run() 

가 대신 DBusGMainLoop 필요 :

여기

if __name__ == '__main__': 
    from gi.repository import GLib 
    loop = GLib.MainLoop() 
    glib_main(set_as_default = True) 
    conn = DBus.SessionBus(mainloop=DBusGMainLoop()) <-- change to --> 
    # conn = DBus.SessionBus(mainloop = glib_main()) <-- as you have it imported --> 
    Notifier(conn, "org.freedesktop.Notifications") 
    loop.run() 

가 setting up the event loop에 대한 링크입니다 당신은 작업 주회 돌이로 DBusGMainLoop와 버스 연결을 작성해야합니다.

또한 오류 메시지에 대해 확신 할 수는 없지만 수행하려고 시도하는 것에 대한 이해에 대한 설명을 조금 더 제공하면 더 많은 답변을 얻을 수 있습니다. 가능하다면 오류 메시지가 표시됩니다.
