Attach JTextField with String property

Hi,

I would like to bind a JTextField with a String in such a way that an
update of JTextField content results in a modification of the String.

Actually it's no more no less than ui-model relation. I searched
around JTextField(Document) constructor, PlainDocument...

Thanks a lot.

Since Strings are immutable that would be impossible.
Perhaps if you elaborate on your end goal, an alternative solution could be
suggested.
You probably just need to add a DocumentListener to the JTextFields
Document.

Would overriding the JTextField's createDefaultModel() method to
return your own version of a PlainDocument object work? The PlainDocument
could be initialized with a class that contains whatever needs to be
modified (say, what the String points to).
