I'm trying to make a card game.

some classes I have are: CardModel, CardView; DeckModel, DeckView.

The deck model has a list of card model, According to MVC, if I want to send a card to a deck, I can add the card model to the deck model, and the card view will be added to the deck view by a event handler.

So I have a addCard(CardModel m) in the DeckModel class, but if I want to send a event to add the card view of that model to the deck view, I only know let the model has a reference to view.

So the question is: If the card model and deck model have to have a reference to their view classes to do it? If not, how to do it better?

Update, the code:

public class DeckModel {
private ArrayList<CardModel> cards;

private ArrayList<EventHandler> actionEventHandlerList;

public void addCard(CardModel card){
    cards.add(card);

    //processEvent(event x);
    //must I pass a event that contain card view here?
}

CardModel getCards(int index){
    return cards.get(index);

}

public synchronized void addEventHandler(EventHandler l){
    if(actionEventHandlerList == null)
        actionEventHandlerList = new ArrayList<EventHandler>();

    if(!actionEventHandlerList.contains(l))
        actionEventHandlerList.add(l);
}

public synchronized void removeEventHandler(EventHandler l){
    if(actionEventHandlerList!= null && actionEventHandlerList.contains(l))
        actionEventHandlerList.remove(l);
}

private void processEvent(Event e){
    ArrayList list;

    synchronized(this){
        if(actionEventHandlerList!= null)
            list = (ArrayList)actionEventHandlerList.clone();
        else
            return;
    }
    for(int i=0; i<actionEventHandlerList.size(); ++i){
        actionEventHandlerList.get(i).handle(e);
    }
}
}
