Enclosing class:
  `JSpinner`

public static class JSpinner.NumberEditor extends JSpinner.DefaultEditor
An editor for a `JSpinner` whose model is a `SpinnerNumberModel`. The value of the editor is displayed with a `JFormattedTextField` whose format is defined by a `NumberFormatter` instance whose `minimum` and `maximum` properties are mapped to the `SpinnerNumberModel`.

Since:
  1.4

- ## Constructor Details

  - ### NumberEditor

    public NumberEditor(JSpinner spinner)
    Construct a `JSpinner` editor that supports displaying and editing the value of a `SpinnerNumberModel` with a `JFormattedTextField`. `This` `NumberEditor` becomes both a `ChangeListener` on the spinner and a `PropertyChangeListener` on the new `JFormattedTextField`.
    Parameters:
      `spinner` - the spinner whose model `this` editor will monitor
    Throws:
      `IllegalArgumentException` - if the spinners model is not an instance of `SpinnerNumberModel`
    See Also:
      - `getModel()`
      - `getFormat()`
      - `SpinnerNumberModel`

  - ### NumberEditor

    public NumberEditor(JSpinner spinner, String decimalFormatPattern)
    Construct a `JSpinner` editor that supports displaying and editing the value of a `SpinnerNumberModel` with a `JFormattedTextField`. `This` `NumberEditor` becomes both a `ChangeListener` on the spinner and a `PropertyChangeListener` on the new `JFormattedTextField`.
    Parameters:
      `spinner` - the spinner whose model `this` editor will monitor
      `decimalFormatPattern` - the initial pattern for the `DecimalFormat` object that's used to display and parse the value of the text field.
    Throws:
      `IllegalArgumentException` - if the spinners model is not an instance of `SpinnerNumberModel` or if `decimalFormatPattern` is not a legal argument to `DecimalFormat`
    See Also:
      - `JSpinner.DefaultEditor.getTextField()`
      - `SpinnerNumberModel`
      - `DecimalFormat`

- ## Method Details

  - ### getFormat

    public DecimalFormat getFormat()
    Returns the `java.text.DecimalFormat` object the `JFormattedTextField` uses to parse and format numbers.
    Returns:
      the value of `getTextField().getFormatter().getFormat()`.
    See Also:
      - `JSpinner.DefaultEditor.getTextField()`
      - `DecimalFormat`

  - ### getModel

    public SpinnerNumberModel getModel()
    Return our spinner ancestor's `SpinnerNumberModel`.
    Returns:
      `getSpinner().getModel()`
    See Also:
      - `JSpinner.DefaultEditor.getSpinner()`
      - `JSpinner.DefaultEditor.getTextField()`
