ScrollContainer
===============

**Inherits:** :ref:`Container<class_Container>` **<** :ref:`Control<class_Control>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

**Inherited By:** :ref:`EditorInspector<class_EditorInspector>`

A helper node for displaying scrollable elements such as lists.

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

A ScrollContainer node meant to contain a :ref:`Control<class_Control>` child.

ScrollContainers will automatically create a scrollbar child (:ref:`HScrollBar<class_HScrollBar>`, :ref:`VScrollBar<class_VScrollBar>`, or both) when needed and will only draw the Control within the ScrollContainer area. 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.minimum_size<class_Control_property_minimum_size>` of the Control relative to the ScrollContainer.

Works great with a :ref:`Panel<class_Panel>` control. You can set ``EXPAND`` on the children's size flags, so they will upscale to the ScrollContainer's size if it's larger (scroll is invisible for the chosen dimension).

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

.. _class_ScrollContainer_method_ensure_control_visible:

- 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)

----

.. _class_ScrollContainer_method_get_h_scroll_bar:

- :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>`.

----

.. _class_ScrollContainer_method_get_v_scroll_bar:

- :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>`.

Theme Property Descriptions
---------------------------
