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

ScrollContainer
- Derived
Remarks
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 custom_minimum_size of the Control relative to the ScrollContainer.

Methods
ensure_control_visible(Control)
Ensures the given control
is visible (must be a direct or indirect child of the ScrollContainer). Used by 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 process_frame:
add_child(child_node)
await get_tree().process_frame
ensure_control_visible(child_node)
void ensure_control_visible(Control control)
Parameters
