Exporting exisiting GObject with GDBus.

[Nicolas CANIART <nicolas caniart net>]

Hi,

  I have been trying to wrap my head around this issue, but after a
few trials and lots of headaches I am still not exactly sure how to
proceed.

I have an interface that is partly implemented by an abstract base
class, then fully implemented by a few (final) classes. I would like
to export the Iface interface via D-Bus (it defines a few methods, 1
(construct-only) property and 2 signals: data-received, closed), on
instances of any of the final classes.

What would be the best way to proceed:
  - redesign the class hierarchy, inserting the GDBusObjectSkeleton
derivated class provided by gdbus-codegen somewhere in here). Then
what needs to be overridden what's need not.

  - create new classes to wrap the intances of the existing classes
and expose them through D-Bus.

  - Or am I "doomed" ? I don't think it has been intended to be used
that way (exporting existing non-dbus objects) and I think that I
should not have defined the Iface interface but have used the D-Bus
interface directly.

My class hierarchy looks like this:

  Iface  (Interface) <--implements-- IfaceBase (Abs. Class)
                                         ^
                                         |
       +---------------------------------+
       |            |        |
  SerialIface   UdpIface  TcpIface


Thanks in advance for any advice, explanation, simple example.
Regards, Nicolas.
