Changing contents of a JList variable

  Asked By: Ryan    Date: Feb 22    Category: Java    Views: 14859
  

I'm trying to change the contents of a JList variable. From what I
remember, I used removeAll() and added a new list within a function.
The following code may contain some errors with regards to exact
function calls.

String[] data = {"a","b","c","d","e","f","g"};
JList list = new JList(data);
changelist(); //only clears list but does not reinitialize variable

void changelist()
{
list.removeAll();
String[] newdata = {"a","b","c","d","e","f","g"};
list = new JList(newdata);
}

Does anybody know what's wrong with this code or if there are
alternatives for creating a URL Address Bar similar in most Web
Browsers?

Try using 'setListData' method.
You don't have to use removeAll().

String[] newdata = {"a","b","c","d","e","f","g"};
list.setListData(newdata);
