I'm building a small application in netbeans,I use a JSpinner component to set the quantity of a product.How can I set the spinner to take only positive values?Is there a choice inside Netbeans that I can set or a method for the JSpinner ?

EXTRA:

spinner.setModel(new SpinnerNumberModel(0, 0, 20, 1));

public void makeUI() { SpinnerModel modeltau = new SpinnerNumberModel(0.0002, 0.0001, 100.0000, 0.0001); JSpinner spinner = new JSpinner(modeltau); ((JSpinner.NumberEditor) spinner.getEditor()).getFormat().setMaximumFractionDigits(4); JFrame frame = new JFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.add(spinner); frame.pack(); frame.setLocationRelativeTo(null); frame.setVisible(true); @jzd - yeah, I had been wondering about those many old references as well. Until I noticed that they come up very high (I remember even as first, cannot reproduce it right now - searching for 'JSpinner' 1.4.2 is second in the list) in a google search. kleopatra Nov 10, 2011 at 9:54 Yes some of the older API's are high on Google's results but I think that is just because there are so many links on the web pages that goolge crawls that point to the old APIs. jzd Nov 10, 2011 at 12:27
