Java: ArrayList with suggested phrases for an auto-complete combobox

Question

I have a method which returns an ArrayList of phrases to be used as the user types characters into a combobox. These phrases would ideally show up in a drop-down menu.

The method is in a class of its own called PhraseList .

I have a GUI class which contains a combobox. How do I go about capturing what the user types in and then get this list of phrases to pop-up in a dropdown menu?

Answer 1

Sounds like you'll need to register a DocumentListener . For more information, see How to Write a Document Listener .

Answer 2

You can extract this/these Char(s) typed into JComboBox or JTextField, by implements Document and with AttributeSet ,

Then you can determine for continious Chars sequence (I think that only for continious), startWith Char(s), contains Char(s),
