Hi
I have a JPanel that uses a cardLayout with several "cards" that are added dinamically in my application. The labels that I use in the cards, however, may change during the application. So, How do I get a "card" from the layout to update (without showing the card)?
I've tryed to add the card to an ArrayList, but when I change the card in the List, the card in the layout does not change.....

Do you really need to get the panel? What you need is a public property that allows you to change the label. Are your panels separate classes? Can you add a property to the class that holds the label?:
public void setMyLabel(String s)
{
myLabel.setText(s);
}
Or perhaps you could use the observer pattern if you want to loosen your connections as much as possible. Anything is possible with enough indirection.
I do have a public method "setMyLabel". But how can I set the label on the right Panel without getting the panel? I have several panels with different text labels to set...
And, As I've said, I've tried to add the panels to a List, so I can get then later, but when I update the panels on the list, the modifications do not appear...
