Yes as I can concatenate the list to a single string that is displayed on 
the QML side with the correct content.

Nope, just normal names.

QML side:

Combobox {
	id: buddyBox
	model: buddyList
}



C++ side:

QStringList QMLManger::buddyList() const
{
	QStringList buddies;
	struct dive *d;
	int i = 0;
	for_each_dive (i, d) {
		buddies << d->buddy;
	}
	buddies.removeDuplicates();
	return buddies;
}
