Thread: Changing colors of items in list dynamically based on external parameter

My requirement:

I have a JList with the list of some store names.
There is a function that checks the online connectivity of the store or the current state of the store.
Based on the return value of the function, I need to highlight those store names correspondingly.

I understand that the JList has a one-dimensional array model. Hence, I cannot save an extra column of data ie. store name, status in the model.

Is there a way I can use that external parameter 'status' in my ListCellRenderer to change the colors of items in my list?

Please give me some pointers.

I got the color rendering done by using an array of objects for every list item.

Now, I have to retrieve a list item based on the selected value. My list model contains 3 columns. But when I retrieve using Object obj = listModel.getselectedItem(index), it returns an Object which is of type Object[3] . However, when I try to access obj[0], i get an error saying it is not an array of objects. The return type of getSelectedItem is an Object. So, I am stuck with this conversion now.

Any ideas?
