JFormattedTextField validation

[Nicol Green]

When I was thinking which to choose JTextField or JFormattedTextField I thought that it would be much easier to program JFormattedTextField, it's name says that, too but now I am dealing with some problems. I consider that should be possible quickly to be done, but not here..

I have a

JFormattedTextField textField = new JFormattedTextField("0.");

I would like to say:

1. inputLenght, not longer then for example 20.
2. Still I cannot use FormattedFactory, because of that initial value. setEditable, or setEnabled is not working in this case.

I feel that it is some trivial solution, or, I hope! So, any tips are welcome! Thank you!

Don't know. I presume you have looked for tutorials like this one?

I think this thread would sit better on our GUIs forum, so I shall move it.

a JTextField with DocumentFilter set might suit you better

Or perhaps all you need to do is use a standard JTextField and simply parse the textfield's text within a try/catch block, catching for NumberFormatException.

Yes definitely, JFormattedTextField was not the best option in my case. I will try what you proposed, and than tell you what was the best solution.

Thanks!
