I have 2 JSpinners in my application , I set the model , editor , number format for both of them. However when I run the application the second one doesn't show the fractional part initially. This Looks like focusing issue.
So first one intialized 0.0 but second one is initialized as 0; I want second one the same with first. Do I miss step here ? Here is my code below.
Here is My Code
import java.text.DecimalFormat;
import javax.swing.JSpinner;
import javax.swing.SpinnerNumberModel;
public class NewJFrame extends javax.swing.JFrame {
private final JSpinner.NumberEditor editor;
DecimalFormat format , format2 ;
private final JSpinner.NumberEditor editor1;
/**
* Creates new form NewJFrame
*/
public NewJFrame() {
initComponents();
SpinnerNumberModel model1 = new SpinnerNumberModel(0.0,-1000.0 ,1000.0,0.1);
this.jSpinner1.setModel(model1);
editor = new JSpinner.NumberEditor(this.jSpinner1);
this.jSpinner1.setEditor(editor);
format = editor.getFormat();
format.setMinimumFractionDigits(1);
SpinnerNumberModel model2 = new SpinnerNumberModel(0.0,-1000.0 ,1000.0,0.1);
this.jSpinner2.setModel(model2);
editor1 = new JSpinner.NumberEditor(this.jSpinner2);
this.jSpinner2.setEditor(editor1);
format2 = editor1.getFormat();
format2.setMinimumFractionDigits(1);
}

You can set format directly to the text field of the editors

Another option is to use a JSpinner.NumberEditor(JSpinner spinner, String decimalFormatPattern):
editor = new JSpinner.NumberEditor(this.jSpinner1, "0.0");
