ScrollContainer¶
Inherits: Container < Control < CanvasItem < Node < Object
Inherited By: EditorInspector
A helper node for displaying scrollable elements such as lists.
Description¶
A ScrollContainer node meant to contain a Control child.
ScrollContainers will automatically create a scrollbar child (HScrollBar, 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 Control.custom_minimum_size of the Control relative to the ScrollContainer.
Works great with a Panel control. You can set Control.SIZE_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).

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
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
Deadzone for touch scrolling. Lower deadzone makes the scrolling more sensitive.
int scroll_horizontal = 0
The current horizontal scroll value.
int scroll_vertical = 0
The current vertical scroll value.
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.
