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);
}
}
}
