i have a jlist which i have implemented the ListCellRenderer .this list consists of images and other stuff whcih is quite expensive for continuous updates.. just like any messenger contact list my list has statuses changing. i can do an update on the list but thats quite an expensive operation. any clues on how to update one item in the list ?
You objects that are represented in the list should belong to a ListModel and then you can iterator over the list model, get the item you need to update, and make your changes. The model will then update the view for you.
