JSpinner in JOptionPane?

I need to put a JSpinner in a JOptionPane. Here is what I've tried:

import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.JSpinner;
import javax.swing.SpinnerNumberModel;

public static void main(String[] args) {
SpinnerNumberModel sModel = new SpinnerNumberModel(0, 0, 30, 1);
JSpinner spinner = new JSpinner(sModel);
JOptionPane.showInputDialog(spinner);
}


Which results in:

How do I remove the textbox?

Answer

You have to use showMessageDialog.

SpinnerNumberModel sModel = new SpinnerNumberModel(0, 0, 30, 1);
JSpinner spinner = new JSpinner(sModel);
JOptionPane.showMessageDialog(null, spinner);

For still having a cancel button, use:

int option = JOptionPane.showOptionDialog(null, spinner, "Enter valid number", JOptionPane.OK_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, null, null);
if (option == JOptionPane.CANCEL_OPTION)
{
    // user hit cancel
} else if (option == JOptionPane.OK_OPTION)
{
    // user entered a number
}
