I am currently using Qt Creator 1.3 to develop my project. But, I am having an issue with a QDBusAbstractAdaptor. It will build the project and run, and it will register the object with the session bus, and everything looks like it is working great.

Using the qdbusviewer I check the object that is on the session bus, it exists but my "D-Bus Interface" does not exists for the object. Only:

org.freedesktop.DBus.Properties
org.freedesktop.DBus.Interospectable
(my dbus interface) <-- MISSING

I am confused on what needs to be done for my interface to be exported on the dbus. Do I need to add something to be project file for qt creator to build the interface. Code is below:

Qt Code: 
  1. QT += sql
  2. QT += dbus
  3. QT -= gui
  4. TARGET = configd
  5. CONFIG += dbus
  6. CONFIG += console
  7. CONFIG -= app_bundle
  8. TEMPLATE = app
  9. SOURCES += main.cpp \
  10.     configdatabase.cpp \
  11.     dbusconfig.cpp \
  12.     watchconfig.cpp
  13. HEADERS += configdatabase.h \
  14.     dbusconfig.h \
  15.     watchconfig.h
