Any idea how I can add a text listener on to a JTextField, that triggers when the text changes and as an action modifies the JTextField's text.
I have tried using addInputMethodListener
which seems to be appropriate but it doesn't seem to work. I have also tried textField.getDocument().addDocumentListener()
but this throws java.lang.IllegalStateException: Attempt to mutate in notification
when I try to modify textField's text.
