JFormattedTextField display commas and accept decimal points
I am using to JFormattedTextField for inputting numbers with decimal points. The following is the formatter.
public static AbstractFormatterFactory createFormatter() {
final NumberFormat format = NumberFormat.getInstance();
final InternationalFormatter formatter = new InternationalFormatter(format);
formatter.setValueClass(Double.class);
formatter.setAllowsInvalid(false);
formatter.setOverwriteMode(true);
formatter.setCommitsOnValidEdit(true);
return new DefaultFormatterFactory(formatter, formatter, formatter);
}
With setAllowsInvalid(false) periods are ignored, but commas are added every 3 digits as desired. With setAllowsInvalid(true) periods are accepted, but commas are not displayed until the focus changes.
Is there a way to have both behaviors?

I have, but what are you suggesting the extended class do/override?

Yes, you can override that method and create logic similar in order to support both..

What is the method you are referring to? The check on allow invalid is within the formatter and uses a private variable.

I believe that JFormattedTextField is made to format differently when editing versus displaying and that was the root of my problem. I have found a very good, if not old, article on using JFormattedTextField that puts everything together nicely. http://www.drdobbs.com/jvm/java-better-interfaces-via-jformattedtex/224700979
