Java Autocomplete TextField (Ajax style)

Question

I need to create a JTextField (or any component where I can type something) and it has to offer a list of dynamicaly populated values. When I type a new character, the propositions are updated (Like Ajax does)

One particularity is that the user can only choose a value that was populated. I need that for my users to select an existing city from a database.

What would be the easiest way to make it with Swing ?

Thank you.

Did you search the forum? The fact that an "autocomplete" tag exists would indicate that questions of this type have been asked before. — camickr, Jan 17 '12 at 15:54

You can implements Auto complete ComboBox / JFextField based on standard Java API, there aren't any issues with Focus or Caret nor with performance for largiest Arrays for autocompleted JComboBox and JTextField

I have used the JIDE Common Layer for autocompletion in Java Swing. Take a look at the WebStart demo.

It's free and open source, and if the provided autocompletion options don't quite match what you are trying to do I found it really easy to plug in my own logic.
