Signals
-------

-  **changed**  **(** **)**
This signal is emitted when min, max, range or step change.

-  **value_changed**  **(** :ref:`float<class_float>` value  **)**
This signal is emitted when value changes.


Description
-----------

Range is a base class for :ref:`Control<class_control>` nodes that change a floating point *value* between a *minimum* and a *maximum*, using *step* and *page*, for example a :ref:`ScrollBar<class_scrollbar>`.

Member Function Description
---------------------------

.. _class_Range_get_as_ratio:

- :ref:`float<class_float>`  **get_as_ratio**  **(** **)** const

Return value mapped to 0 to 1 range.

.. _class_Range_get_max:

- :ref:`float<class_float>`  **get_max**  **(** **)** const

Return the maximum value.

.. _class_Range_get_min:

- :ref:`float<class_float>`  **get_min**  **(** **)** const

Return the minimum value.

.. _class_Range_get_page:

- :ref:`float<class_float>`  **get_page**  **(** **)** const

Return the page size, if page is 0, paging is disabled.

.. _class_Range_get_step:

- :ref:`float<class_float>`  **get_step**  **(** **)** const

Return the stepping, if step is 0, stepping is disabled.

.. _class_Range_get_value:

- :ref:`float<class_float>`  **get_value**  **(** **)** const

.. _class_Range_is_ratio_exp:

- :ref:`bool<class_bool>`  **is_ratio_exp**  **(** **)** const

.. _class_Range_is_using_rounded_values:

- :ref:`bool<class_bool>`  **is_using_rounded_values**  **(** **)** const

.. _class_Range_set_as_ratio:

- void  **set_as_ratio**  **(** :ref:`float<class_float>` value  **)**

Set value mapped to 0 to 1 (unit) range, it will then be converted to the actual value within min and max.

.. _class_Range_set_exp_ratio:

- void  **set_exp_ratio**  **(** :ref:`bool<class_bool>` enabled  **)**

.. _class_Range_set_max:

- void  **set_max**  **(** :ref:`float<class_float>` maximum  **)**

.. _class_Range_set_min:

- void  **set_min**  **(** :ref:`float<class_float>` minimum  **)**

Set minimum value, clamped range value to it if it's less.

.. _class_Range_set_page:

- void  **set_page**  **(** :ref:`float<class_float>` pagesize  **)**

Set page size. Page is mainly used for scrollbars or anything that controls text scrolling.

.. _class_Range_set_step:

- void  **set_step**  **(** :ref:`float<class_float>` step  **)**

Set step value. If step is 0, stepping will be disabled.

.. _class_Range_set_use_rounded_values:

- void  **set_use_rounded_values**  **(** :ref:`bool<class_bool>` enabled  **)**

.. _class_Range_set_value:

- void  **set_value**  **(** :ref:`float<class_float>` value  **)**

.. _class_Range_share:

- void  **share**  **(** :ref:`Node<class_node>` with  **)**

.. _class_Range_unshare:

- void  **unshare**  **(** **)**
