jspinner

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)); for JSpinner you have to implements SpinnerNumberModel import javax.swing.*; public class SpinnerModelTest { public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { public void run() { new SpinnerModelTest().makeUI(); } }); } public void makeUI() { SpinnerModel

I am writing part of my program which read data from a txt file. I have problem when I want to set value of JSpinner by setValue(object). My data is double so I need to convert it to object, but how? LoadData open = new LoadData(); data.setFz(open.giveAwayData()); spinner_1.setValue(data.getFz()); // Fz is double Try casting it to Double (with capital): spinner_1.setValue((Double) data.getFz()); bcsb1001 Use Double.valueOf(data.getFz()) . An explanation of the differences between primitives and boxed primitives can be found here ; basically, primitives have better performance but the boxed

I'm using a jSpinner to set the time with format "HH:MM" and it works fine. My problem is I want to set my jSpinner to "00:00" when the window is activated, and once jSpinner is clicked I want the value to be changed to the "HH:MM" format. And I can't do it myself, the jSpinner value doesn't change it is still "00:00". Please help me. Thank you in advance. Assuming that your are using a SpinnerDateModel , then the value that the JSpinner is managing is java.util.Date . You need to create a Date instance which has it's hour/minute fields set to midnight Calendar cal = Calendar.getInstance();

I am working in a java swing application. In that application i have to take time input from user. I need to make a JSpinner for the time, only in the hh:mm am/pm format. i searched in properties but could not get this format. Please suggest me some way to display time in hh:mm am/pm format. I thank to all your valuable suggestions. You can set an editor and a date model like this: SpinnerDateModel model = new SpinnerDateModel(); model.setCalendarField(Calendar.MINUTE); spinner= new JSpinner(); spinner.setModel(model); spinner.setEditor(new JSpinner.DateEditor(spinner, "h:mm a")); Thanks for

i'm using a JSpinner like a table cell editor, i have one annoying problem: The cell remains in NON-editable mode until i click into it, for NON-editable i mean that i can't write into it(it has not focus so it doesn't accept inputs keyboard) but i can change the value with up-down arrows(of keyboard). So, what i have to do to focus my table cell as soon as i press a key when it is selected? Except for that problem my SpinnerEditor class works quite well. Thanks all. Here's a complete example. It does more than just put the JSpinner in the table, so you can read it and take what you need. I

I'm making an application that uses a JSpinner with a max number 30,I should choose a value from this JSpinner and tape a String to the JTextField and the result will appear in the Textarea,when I compile I have many problems concerning the method jSpinner1State,can any one help me because I don't know where is my problem. This is my code of the method JSpinner: jSpinner1.addChangeListener(this); private void jSpinner1StateChanged(javax.swing.event.ChangeEvent evt) { // TODO add your handling code here: Object sp=jSpinner1.getValue(); int i =Integer.parseInt(sp.toString() ); String targetIP

I'm creating a JSpinner and setting a NumberEditor with a custom format. But no matter what I do the format uses "." instead of ",", not according to my locale (pt_BR). priceSpinner = new JSpinner(); priceSpinner.setEditor(new JSpinner.NumberEditor(priceSpinner, "0.00")); Is it possible to use "," instead of "." as a decimal separator? By specifying a custom format pattern you are telling the JRE to ignore your locale and use that specific format. If you are simply after a spinner for numbers to two decimal places, use setModel() instead of setEditor() which will create a NumberEditor for you:
