ScrollContainer

Inherits: Container < Control < CanvasItem < Node < Object

Inherited By: EditorInspector

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

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 Control.custom_minimum_size of the Control relative to the ScrollContainer.

Signals

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 ProjectSettings.input_devices/pointing/emulate_touch_from_mouse is enabled.

scroll_started ( )

Emitted when scrolling starts 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 ProjectSettings.input_devices/pointing/emulate_touch_from_mouse is enabled.

Enumerations

enum ScrollMode:

ScrollMode SCROLL_MODE_DISABLED = 0

Scrolling disabled, scrollbar will be invisible.

ScrollMode SCROLL_MODE_AUTO = 1

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

ScrollMode SCROLL_MODE_SHOW_ALWAYS = 2

Scrolling enabled, scrollbar will be always visible.

ScrollMode SCROLL_MODE_SHOW_NEVER = 3

Scrolling enabled, scrollbar will be hidden.

Property Descriptions

bool follow_focus = false

• void set_follow_focus ( bool value )

• bool is_following_focus ( )

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

ScrollMode horizontal_scroll_mode = 1

• void set_horizontal_scroll_mode ( ScrollMode value )

• ScrollMode get_horizontal_scroll_mode ( )

Controls whether horizontal scrollbar can be used and when it should be visible. See ScrollMode for options.

int scroll_deadzone = 0

• void set_deadzone ( int value )

• int get_deadzone ( )

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

int scroll_horizontal = 0

• void set_h_scroll ( int value )

• int get_h_scroll ( )

The current horizontal scroll value.

Note: If you are setting this value in the Node._ready function or earlier, it needs to be wrapped with Object.set_deferred, since scroll bar’s Range.max_value is not initialized yet.

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

float scroll_horizontal_custom_step = -1.0

• void set_horizontal_custom_step ( float value )

• float get_horizontal_custom_step ( )

Overrides the ScrollBar.custom_step used when clicking the internal scroll bar’s horizontal increment and decrement buttons or when using arrow keys when the ScrollBar is focused.

int scroll_vertical = 0

• void set_v_scroll ( int value )

• int get_v_scroll ( )

The current vertical scroll value.

Note: Setting it early needs to be deferred, just like in scroll_horizontal.

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

float scroll_vertical_custom_step = -1.0

• void set_vertical_custom_step ( float value )

• float get_vertical_custom_step ( )

Overrides the ScrollBar.custom_step used when clicking the internal scroll bar’s vertical increment and decrement buttons or when using arrow keys when the ScrollBar is focused.

ScrollMode vertical_scroll_mode = 1

• void set_vertical_scroll_mode ( ScrollMode value )

• ScrollMode get_vertical_scroll_mode ( )

Controls whether vertical scrollbar can be used and when it should be visible. See ScrollMode for options.

Method Descriptions

void ensure_control_visible ( Control 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 SceneTree.process_frame:

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

HScrollBar get_h_scroll_bar ( )

Returns the horizontal scrollbar 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 horizontal_scroll_mode.

VScrollBar get_v_scroll_bar ( )

Returns the vertical scrollbar 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 vertical_scroll_mode.
