A container used to provide scrollbars to a child control when needed.

.. rst-class:: classref-introduction-group

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

A container used to provide a child control with scrollbars when needed. Scrollbars will automatically be drawn at the right (for vertical) or bottom (for horizontal) and will enable dragging to move the viewable Control (and its children) within the ScrollContainer. Scrollbars will also automatically resize the grabber based on the :ref:`Control.custom_minimum_size<class_Control_property_custom_minimum_size>` of the Control relative to the ScrollContainer.

Signals
-------

.. _class_ScrollContainer_signal_scroll_ended:

.. rst-class:: classref-signal

**scroll_ended** **(** **)**

Emitted when scrolling stops when dragging the scrollable area *with a touch event*. This signal is *not* emitted when scrolling by dragging the scrollbar, scrolling with the mouse wheel or scrolling with keyboard/gamepad events.

\ **Note:** This signal is only emitted on Android or iOS, or on desktop/web platforms when :ref:`ProjectSettings.input_devices/pointing/emulate_touch_from_mouse<class_ProjectSettings_property_input_devices/pointing/emulate_touch_from_mouse>` is enabled.

.. rst-class:: classref-item-separator

----

.. _class_ScrollContainer_signal_scroll_started:

.. rst-class:: classref-signal

**scroll_started** **(** **)**

Emitted when scrolling starts when dragging the scrollable area w\ *ith a touch event*. This signal is *not* emitted when scrolling by dragging the scrollbar, scrolling with the mouse wheel or scrolling with keyboard/gamepad events.

\ **Note:** This signal is only emitted on Android or iOS, or on desktop/web platforms when :ref:`ProjectSettings.input_devices/pointing/emulate_touch_from_mouse<class_ProjectSettings_property_input_devices/pointing/emulate_touch_from_mouse>` is enabled.

Enumerations
------------

.. _enum_ScrollContainer_ScrollMode:

.. rst-class:: classref-enumeration

enum **ScrollMode**:

.. _class_ScrollContainer_constant_SCROLL_MODE_DISABLED:

.. rst-class:: classref-enumeration-constant

:ref:`ScrollMode<enum_ScrollContainer_ScrollMode>` **SCROLL_MODE_DISABLED** = ``0``

Scrolling disabled, scrollbar will be invisible.

.. _class_ScrollContainer_constant_SCROLL_MODE_AUTO:

.. rst-class:: classref-enumeration-constant

:ref:`ScrollMode<enum_ScrollContainer_ScrollMode>` **SCROLL_MODE_AUTO** = ``1``

Scrolling enabled, scrollbar will be visible only if necessary, i.e. container's content is bigger than the container.

.. _class_ScrollContainer_constant_SCROLL_MODE_SHOW_ALWAYS:

.. rst-class:: classref-enumeration-constant

:ref:`ScrollMode<enum_ScrollContainer_ScrollMode>` **SCROLL_MODE_SHOW_ALWAYS** = ``2``

Scrolling enabled, scrollbar will be always visible.

.. _class_ScrollContainer_constant_SCROLL_MODE_SHOW_NEVER:

.. rst-class:: classref-enumeration-constant

:ref:`ScrollMode<enum_ScrollContainer_ScrollMode>` **SCROLL_MODE_SHOW_NEVER** = ``3``

Scrolling enabled, scrollbar will be hidden.

Property Descriptions
---------------------

.. _class_ScrollContainer_property_follow_focus:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **follow_focus** = ``false``

- void **set_follow_focus** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_following_focus** **(** **)**

If ``true``, the ScrollContainer will automatically scroll to focused children (including indirect children) to make sure they are fully visible.

.. rst-class:: classref-item-separator

----

.. _class_ScrollContainer_property_horizontal_scroll_mode:

.. rst-class:: classref-property

:ref:`ScrollMode<enum_ScrollContainer_ScrollMode>` **horizontal_scroll_mode** = ``1``

.. rst-class:: classref-property-setget

- void **set_horizontal_scroll_mode** **(** :ref:`ScrollMode<enum_ScrollContainer_ScrollMode>` value **)**
- :ref:`ScrollMode<enum_ScrollContainer_ScrollMode>` **get_horizontal_scroll_mode** **(** **)**

- void **set_deadzone** **(** :ref:`int<class_int>` value **)**
- :ref:`int<class_int>` **get_deadzone** **(** **)**

Deadzone for touch scrolling. Lower deadzone makes the scrolling more sensitive.

.. rst-class:: classref-item-separator

----

.. _class_ScrollContainer_property_scroll_horizontal:

.. rst-class:: classref-property

:ref:`int<class_int>` **scroll_horizontal** = ``0``

- void **set_h_scroll** **(** :ref:`int<class_int>` value **)**
- :ref:`int<class_int>` **get_h_scroll** **(** **)**

The current horizontal scroll value.

\ **Note:** If you are setting this value in the :ref:`Node._ready<class_Node_private_method__ready>` function or earlier, it needs to be wrapped with :ref:`Object.set_deferred<class_Object_method_set_deferred>`, since scroll bar's :ref:`Range.max_value<class_Range_property_max_value>` is not initialized yet.

::

    func _ready():
        set_deferred("scroll_horizontal", 600)

.. rst-class:: classref-item-separator

----

.. _class_ScrollContainer_property_scroll_horizontal_custom_step:

.. rst-class:: classref-property

:ref:`float<class_float>` **scroll_horizontal_custom_step** = ``-1.0``

.. rst-class:: classref-property-setget

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

Overrides the :ref:`ScrollBar.custom_step<class_ScrollBar_property_custom_step>` used when clicking the internal scroll bar's horizontal increment and decrement buttons or when using arrow keys when the :ref:`ScrollBar<class_ScrollBar>` is focused.

.. rst-class:: classref-item-separator

----

.. _class_ScrollContainer_property_scroll_vertical:

.. rst-class:: classref-property

:ref:`int<class_int>` **scroll_vertical** = ``0``

.. rst-class:: classref-property-setget

- void **set_v_scroll** **(** :ref:`int<class_int>` value **)**
- :ref:`int<class_int>` **get_v_scroll** **(** **)**

The current vertical scroll value.

\ **Note:** Setting it early needs to be deferred, just like in :ref:`scroll_horizontal<class_ScrollContainer_property_scroll_horizontal>`.

::

    func _ready():
        set_deferred("scroll_vertical", 600)

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

Method Descriptions
-------------------

.. _class_ScrollContainer_method_ensure_control_visible:

.. rst-class:: classref-method

void **ensure_control_visible** **(** :ref:`Control<class_Control>` control **)**

Ensures the given ``control`` is visible (must be a direct or indirect child of the ScrollContainer). Used by :ref:`follow_focus<class_ScrollContainer_property_follow_focus>`.

\ **Note:** This will not work on a node that was just added during the same frame. If you want to scroll to a newly added child, you must wait until the next frame using :ref:`SceneTree.process_frame<class_SceneTree_signal_process_frame>`:

::

    add_child(child_node)
    await get_tree().process_frame
    ensure_control_visible(child_node)

.. rst-class:: classref-item-separator

----

.. _class_ScrollContainer_method_get_h_scroll_bar:

.. rst-class:: classref-method

:ref:`HScrollBar<class_HScrollBar>` **get_h_scroll_bar** **(** **)**

Returns the horizontal scrollbar :ref:`HScrollBar<class_HScrollBar>` of this **ScrollContainer**.

\ **Warning:** This is a required internal node, removing and freeing it may cause a crash. If you wish to disable or hide a scrollbar, you can use :ref:`horizontal_scroll_mode<class_ScrollContainer_property_horizontal_scroll_mode>`.

.. rst-class:: classref-item-separator

----

.. _class_ScrollContainer_method_get_v_scroll_bar:

.. rst-class:: classref-method

:ref:`VScrollBar<class_VScrollBar>` **get_v_scroll_bar** **(** **)**

Returns the vertical scrollbar :ref:`VScrollBar<class_VScrollBar>` of this **ScrollContainer**.

\ **Warning:** This is a required internal node, removing and freeing it may cause a crash. If you wish to disable or hide a scrollbar, you can use :ref:`vertical_scroll_mode<class_ScrollContainer_property_vertical_scroll_mode>`.
