如何设置JSpinner的值的位置

Question

我在我的Java代码中使用了JSpinner，在JSpinner中，JSpinner的值显示在JSpinner的右侧，但我希望JSpinner的值应出现在JSpinner的左侧，所以请告诉我该怎么做那？？？

Have you tried getting the JSpinner's editor via getEditor(), and then from that getting its textfield via getTextField(). You could probably set its orientation.

import javax.swing.*;
import javax.swing.JSpinner.DefaultEditor;

public class OppositeSpinner {
   public static void main(String[] args) {
      JSpinner spinner = new JSpinner(new SpinnerNumberModel(50, 0, 100, 1));
      JFormattedTextField textField = ((DefaultEditor) spinner.getEditor()).getTextField();
      textField.setHorizontalAlignment(JTextField.LEFT);
      JOptionPane.showMessageDialog(null, spinner);
   }
}

Alternatively, you could change the Look and Feel's value for the Spinner.editorAlignment property via the UIManager.put(...) method. eg,

UIManager.put("Spinner.editorAlignment", JTextField.LEFT);

For a more complete example:

public static void main(String[] args) {
  UIManager.put("Spinner.editorAlignment", JTextField.LEFT);
  JSpinner spinner = new JSpinner(new SpinnerNumberModel(50, 0, 100, 1));
  JOptionPane.showMessageDialog(null, spinner);
}
