I have continued a bit on my track to do a real model view separation for the Citation Dialog. In this new scheme, QCitation is the controller and the model at the same time, it inherits ControlCitation and it doesn't know about the view. QCitationDialog is the view, it is using QCitation to get its model and for communication with the core; it is inheriting Dialog::View directly.

In frontend/qt4/Dialog.C, we use these class like this:

    } else if (name == "citation") {
        QCitation * ci = new QCitation(*dialog);
        dialog->setController(ci);
        dialog->setView(new QCitationDialog(*dialog, ci));
        dialog->bc().bp(new NoRepeatedApplyReadOnlyPolicy);

Now, it should be possible to define another view like this:

    } else if (name == "citation-inline") {
        QCitation * ci = new QCitation(*dialog);
        dialog->setController(ci);
        dialog->setView(new QCitationInline(*dialog, ci));

All the citation functionalities are not there yet but the basic ones are there. There are still a few "intelligence" still to be transfered from the view to the dialog.
