I have not paid enough attention to kafka for some time. So I'm plesently surprised
to see you got this far in so little time ;)

What confuses me is that I can not load/display a html file in the CVS version. I
am sure this has been done allready since you are thinking about ways to edit it.

Confused...

This is an implementation thing. I can not comment on this without knowing the code ;)

I was personally thinking a bit more pluggable.
In the view you catch the mouseclick like this:

KafkaView::contentsMousePressEvent(MousePressEvent *e ) {
    // We get called by QT when something is clicked.

    // pluginType1 is a QList of plugins that want to get notified 
    // when another node has been selected.
    // for instance QList<PluginBase> pluginType;    
    for (unsigned int i=0; i < pluginType1->count(); i++) {
        pluginType1->at(i)->setCurrentSelectedObject(node);
    }
}


The objectEditor is a plugin and thus inharits from the pluginbase. Therefor
it must implement the setCurrentSelectedObject method. This can be done as follows.

KafkaObjectEditor::setCurrentSelectedObject(BaseDomObject *object) {
    case object->type(); {
        "P":   // set up text editing gui
          break;
        "TABLE": // set up table editing gui
         break;
    }
}
