How Do I Refresh Components in a Java Swing GUI?
I have a JList that is defined as
private final JList _list = new JList(getList());
where getList() returns a String array.
I can change the String array elsewhere in the GUI so how can I have the JList refresh with the new options everytime I make a change? Is there some sort of
function that I could call?
I also have the same problem with a JTextArea defined as
private final JTextArea _textArea = new JTextArea(getMessage());
where getMessage() returns a string. How can I have them refresh?
