      See Also:
        Number - Spinner Example

    - #### getStep

        Number - Spinner Example

    - #### setDefaultProperties

          public static void setDefaultProperties(SpinnerItem spinnerItemProperties)

      Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties of the class instance passed to this function. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

      Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

      Parameters:
        `spinnerItemProperties` - properties that should be used as new defaults when instances of this class are created

    - #### setMax

          public final void setMax(java.lang.Integer max)

    - #### setMin

          public final void setMin(java.lang.Integer min)

    - #### setDefaultValue

          public void setDefaultValue(java.lang.Double defaultValue)

      Description copied from class: `FormItem`
      Value used when no value is provided for this item. Note that whenever this item's value is cleared by the user or set to `null` programmatically, it will be reverted to the `defaultValue`. Developers should use the `values` object if their intention is to provide an initial value for a field in a form rather than a value to use in place of `null`.
      Overrides:
        `setDefaultValue` in class `FormItem`
      Parameters:
        `defaultValue` - defaultValue Default value is null

    - #### setDefaultValue

          public void setDefaultValue(java.lang.Integer defaultValue)

      Description copied from class: `FormItem`
      Value used when no value is provided for this item. Note that whenever this item's value is cleared by the user or set to `null` programmatically, it will be reverted to the `defaultValue`. Developers should use the `values` object if their intention is to provide an initial value for a field in a form rather than a value to use in place of `null`.
      Overrides:
        `setDefaultValue` in class `FormItem`
      Parameters:
        `defaultValue` - defaultValue Default value is null

    - #### setNextValueHandler

          public void setNextValueHandler(NextValueHandler handler)

      When `min` and `max` are both null or unspecified, the nextValueHandler is used to get the next higher value from the currentValue. The default implementation returns (currentValue + step).

      To indicate that the given currentValue is the maximum value, return currentValue again.

      Implementations should expect to be passed any value for currentValue. Also, if `step` is non-negative, the nextValueHandler must induce a monotonically increasing (non-decreasing) function; otherwise, the nextValueHandler must induce a monotonically decreasing function.

    - #### setPreviousValueHandler

          public void setPreviousValueHandler(PreviousValueHandler handler)

      When `min` and `max` are both null or unspecified, the previousValueHandler is used to get the previous lower value from the currentValue. The default implementation returns (currentValue + step) because the step parameter is based on the opposite of `this.step`.

      To indicate that the given currentValue is the minimum value, return currentValue again.

      Implementations should expect to be passed any value for currentValue. Also, if `step` is non-negative, the previousValueHandler must induce a monotonically decreasing (non-increasing) function; otherwise, the previousValueHandler must induce a monotonically increasing function.
