Akonadi DBus Interface Contacts

[Klaas Freitag]

Hi,

in Kraft [1], I have a nice connector to Akonadi to read contacts, that 
works basically like this (example):

--
     Akonadi::ContactSearchJob *csjob = new Akonadi::ContactSearchJob( 
this );
     csjob->setLimit( 1 );
     csjob->setQuery(ContactSearchJob::ContactUid , uid, 
ContactSearchJob::ExactMatch);

     csjob->setProperty("UID", uid);
     connect( csjob, SIGNAL( result( KJob* ) ), this, SLOT( 
searchResult( KJob* ) ) );
     csjob->start();
     ...
--

That works nicely and users (and myself) are happy.

But with an AppImage of Kraft, this connection does not work any more 
because of the bin dependency into the host system. AppImage builds have 
a hard time to connect to the host Akonadi. That is an unfortunate downside.

To solve that, I was wondering if a connection via DBus would help. If 
Kraft could
1. query single contacts by the Uid, and
2. get a list of all contacts (with limited set of attributes) of a 
resource to build a model for a selection widget
from Akonadi Contacts via DBus, that would solve the problem in the 
AppImage.

Is that assumption right? Is Akonadi offering such a DBus interface?
If so, is there any example code somewhere?

Thanks for enlighten me,

Klaas
