Java Swing - a good textfield component for numbers?

Question

i am bit new to java and swing so... can someone please tell me how to utilize swing textfield component for number processing (money, decimal...) ? or can someone tell me where to find swing component witch is designed for this ? I am building a small ERP app, and standard Swing or SwingX simple do not have a good number processing component)

(FormattedTextField is no good!)

Answer 1

JSpinner is designed for numbers. But what kind of number processing do you need from the component?

Answer 2

I've implemented number fields based on JFormattedTextField.

They also support a min and a max value.

Maybe you find them useful (the library is open source):
