public class DateRangeItem extends CanvasItem
Allows a user to select an absolute or relative range of dates via two `RelativeDateItem`s (if `allowRelativeDates` is true) or two `DateItems`.

The item's `data type` is expected to be one of "date" or "datetime" and dictates whether the dates in the range include a time portion. If unset and the item's form is databound, the data type is detected from the associated `dataSource field`. If there is no such field, or the form is not databound, the default data type value is "date".

DateRangeItem is just a convenience relative to using two `RelativeDateItem` or `DateItem` controls in a form, then using `FormItem.operator` and `FormItem.criteriaField` to cause them to produce a date range. If you need more control over layout, validation, event handling or any other aspect of appearance or behavior, stop using DateRangeItem and use two DateItem/RelativeDateItem controls directly instead.

    public static void changePickerIconDefaults(FormItemIcon defaults)

  - ### getAbsoluteDateTimeItemConstructor

    public String getAbsoluteDateTimeItemConstructor()
    The `FormItem` class to create when `allowRelativeDates` is false, and the `DateRangeItem`'s type is "datetime".
    Returns:
      Current absoluteDateTimeItemConstructor value. Default value is "DateTimeItem"
    See Also:
      - `FieldType`

  - ### getAbsoluteItemConstructor

    public String getAbsoluteItemConstructor()
    The `FormItem` class to create when `allowRelativeDates` is false, but the `DateRangeItem` does not have type "datetime".
    Returns:
      Current absoluteItemConstructor value. Default value is "DateItem"
    See Also:
      - `FieldType`

  - ### setAllowRelativeDates

    public DateRangeItem setAllowRelativeDates(Boolean allowRelativeDates)
    Whether to allow the user to specify relative dates (via `RelativeDateItem`s) or whether dates are absolute (via `DateItem`s).
    Parameters:
      `allowRelativeDates` - New allowRelativeDates value. Default value is false
    Returns:
      `DateRangeItem` instance, for chaining setter calls

  - ### getAllowRelativeDates

    public Boolean getAllowRelativeDates()
    Whether to allow the user to specify relative dates (via `RelativeDateItem`s) or whether dates are absolute (via `DateItem`s).
    Returns:
      Current allowRelativeDates value. Default value is false

  - ### getDateRangeForm

    public DynamicForm getDateRangeForm()
    `DynamicForm` `com.smartgwt.client.types.AutoChild` automatically created by the dateRangeItem and applied to the item as `this.canvas`.

    This DynamicForm contains the "from" and "to" fields the user will interact with to actually select a date-range. Note that as a standard autoChild, developers may customize this form by modifying `dateRangeProperties`.

    This component is an AutoChild named "dateRangeForm". For an overview of how to use and configure AutoChildren, see `Using AutoChildren`.

    Returns:
      Current dateRangeForm value. Default value is null

  - ### setFieldLayout

    public DateRangeItem setFieldLayout(DateFieldLayout fieldLayout)
    Controls the placement of the `toField` and `fromField` in the `dateRangeForm`.

    Note that we don't recommend "horizontal" placement for mobile, and we also don't recommend it for `allowRelativeDates` mode, since `RelativeDateItem` changes width drastically during editing, which causes a lot of unpleasant side-to-side shifting of controls.

    Parameters:
      `fieldLayout` - New fieldLayout value. Default value is "vertical"
    Returns:
      `DateRangeItem` instance, for chaining setter calls

  - ### getFieldLayout

    public DateFieldLayout getFieldLayout()
    Controls the placement of the `toField` and `fromField` in the `dateRangeForm`.

    Note that we don't recommend "horizontal" placement for mobile, and we also don't recommend it for `allowRelativeDates` mode, since `RelativeDateItem` changes width drastically during editing, which causes a lot of unpleasant side-to-side shifting of controls.

    Returns:
      Current fieldLayout value. Default value is "vertical"

  - ### setFormula

    public DateRangeItem setFormula(UserFormula formula)
    Not applicable to a DateRangeItem.
    Overrides:
      `setFormula` in class `FormItem`
    Parameters:
      `formula` - New formula value. Default value is null
    Returns:
      `DateRangeItem` instance, for chaining setter calls
    See Also:
      - `FormulaFields overview and related methods`

  - ### getFormula

    public UserFormula getFormula()
    Not applicable to a DateRangeItem.
    Overrides:
      `getFormula` in class `FormItem`

  - ### setDefaultProperties

    public static void setDefaultProperties(DateRangeItem dateRangeItemProperties)
    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:
      `dateRangeItemProperties` - properties that should be used as new defaults when instances of this class are created
    See Also:
      - `SGWTProperties`

  - ### setFromDate

    public void setFromDate(Date fromDate)
    Initial value for the "from" date. Sets the `fromDate` for this DateRangeItem.
    Parameters:
      `fromDate` - the date from which this item should start it's range. Default value is today

  - ### getFromDate

    public Date getFromDate()
    Initial value for the "from" date.
    Returns:
      java.util.Date

  - ### getValue

    public DateRange getValue()
    Retrieves the current value of this dateRangeItem. The return value is a `DateRange` object that excludes start and end values if they aren't set.
    Overrides:
      `getValue` in class `FormItem`
    Returns:
      the current value of this item

  - ### setValue

    public void setValue(DateRange value)
    Sets the value for this dateRangeItem. The value parameter is a `DateRange` object that optionally includes both start and end values.
    Parameters:
      `value` - the new value for this item

  - ### setCanEditCriterionPredicate

    public void setCanEditCriterionPredicate(FormItemCanEditCriterionPredicate predicate)
    The default `canEditCriterion()` predicate returns true if the specified criterion contains:
    - A single "lessOrEqual" or "greaterOrEqual" criterion on this field
    - An "and" type criterion containing a "lessOrEqual" and a "greaterOrEqual" criterion on this field
    - A single "equals" criterion. Internally, this will be converted into a range by constructing an "and" type criterion containing both a "lessOrEqual" and a "greaterOrEqual" criterion on this field. Note that subsequent calls to the `FormItemCriterionGetter`'s `getCriterion()` method will return this more complex criterion.
    Overrides:
      `setCanEditCriterionPredicate` in class `CanvasItem`
    Parameters:
      `predicate` - the predicate to determine the form items that can edit the criterion in question
    See Also:
      - `FormItem.setCanEditCriterionPredicate`
      - `CriteriaEditing overview and related methods`

  - ### setCriterionSetter

    public void setCriterionSetter(FormItemCriterionSetter setter)
    The default `setCriterion()` implementation applies the specified criterion to this item for editing. Applies any specified "greaterOrEqual" operator criterion or sub-criterion to our `fromField` and any specified "lessOrEqual" operator criterion or sub-criterion to our `toField`.

    Note that a single "equals" criterion can also be passed. See `setCanEditCriterionPredicate()` for more detail.

    Overrides:
      `setCriterionSetter` in class `CanvasItem`
    Parameters:
      `setter` - provides a method to update this field with the edited criterion
