JFormattedTextField

[dcalladi]

Hi Guys,
I'm looking the syntax for a input mask that will allow me to input
1.23, 12.34, 123.45 into the JFormattedTextField
i found something like ###.## but that doesn't work
but something like ###-## wud work.
just wondering if anyone knows how to do this with a mask or currency format or number format

you have to set NumberFormat for JFormattedTextField, maybe use JSpinner with SpinnerNumberModel

            public AbstractFormatter getFormatter(JFormattedTextField tf) {

                format.setMinimumFractionDigits(2);
