## 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()`
