This property is set to the maximum of the [CanvasSize](/docs/reference/engine/classes/ScrollingFrame.md) property and the size of the children if [AutomaticCanvasSize](/docs/reference/engine/classes/ScrollingFrame.md) is set to something other than [AutomaticSize.None](/docs/reference/engine/enums/AutomaticSize.md). ### Property: ScrollingFrame.AbsoluteWindowSize ```json { "type": "Vector2", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": false, "can_save": true }, "thread_safety": "Unsafe", "category": "Scrolling", "capabilities": [ "UI" ] } ``` The size of the frame, in offsets, without the scroll bars. ### Property: ScrollingFrame.AutomaticCanvasSize ```json { "type": "AutomaticSize", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Scrolling", "capabilities": [ "UI" ] } ``` This property is used to automatically size parent UI objects based on the size of its descendants. You can use this property to dynamically add text and other content to a `ScrollingFrame` at edit or run time and the size will adjust to fit that content. When this property is set to an [AutomaticSize](/docs/reference/engine/enums/AutomaticSize.md) value other than [None](/docs/reference/engine/enums/AutomaticSize.md), [AbsoluteCanvasSize](/docs/reference/engine/classes/ScrollingFrame.md) may resize depending on its child content. ### Property: ScrollingFrame.BottomImage ```json { "type": "ContentId", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Scrolling", "capabilities": [ "UI" ] } ``` Image that displays on the bottom of a vertical scroll bar, or the right of a horizontal scroll bar (rotated 90° counterclockwise for a horizontal scroll bar). ![Diagram showing the three image asset elements which construct a scrolling frame's scroll bar.](/assets/ui/ui-objects/ScrollingFrame-Scroll-Bar-Elements.png) ### Property: ScrollingFrame.BottomImageContent ```json { "type": "Content", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Scrolling", "capabilities": [ "UI" ] } ``` Image that displays on the bottom of a vertical scroll bar, or the right of a horizontal scroll bar (rotated 90° counterclockwise for a horizontal scroll bar). ![Diagram showing the three image asset elements which construct a scrolling frame's scroll bar.](/assets/ui/ui-objects/ScrollingFrame-Scroll-Bar-Elements.png) ### Property: ScrollingFrame.CanvasPosition ```json { "type": "Vector2", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Scrolling", "capabilities": [ "UI" ] } ``` Reflects the **current** positional offset of the canvas within the frame, in pixels, and sets the position of scroll bars accordingly. Note that this property doesn't do anything if scroll bars aren't visible. ### Property: ScrollingFrame.CanvasSize ```json { "type": "UDim2", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Scrolling", "capabilities": [ "UI" ] } ``` Determines the size of the scrollable area. For an adaptive alternative based on the overall size of children within the `ScrollingFrame`, consider using [AutomaticCanvasSize](/docs/reference/engine/classes/ScrollingFrame.md). ### Property: ScrollingFrame.ElasticBehavior ```json { "type": "ElasticBehavior", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Scrolling", "capabilities": [ "UI" ] } ``` This property determines if and when elastic scrolling is allowed on touch‑enabled devices. Defaults to [WhenScrollable](/docs/reference/engine/enums/ElasticBehavior.md). ### Property: ScrollingFrame.HorizontalScrollBarInset ```json { "type": "ScrollBarInset", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Scrolling", "capabilities": [ "UI" ] } ``` Indicates whether [CanvasSize](/docs/reference/engine/classes/ScrollingFrame.md) is inset by [ScrollBarThickness](/docs/reference/engine/classes/ScrollingFrame.md) on the horizontal axis. ### Property: ScrollingFrame.MidImage ```json { "type": "ContentId", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Scrolling", "capabilities": [ "UI" ] } ``` Image which spans the area between [TopImage](/docs/reference/engine/classes/ScrollingFrame.md) and [BottomImage](/docs/reference/engine/classes/ScrollingFrame.md) (rotated 90° counterclockwise for a horizontal scroll bar). This image automatically scales to fill the space between the cap segments. ![Diagram showing the three image asset elements which construct a scrolling frame's scroll bar.](/assets/ui/ui-objects/ScrollingFrame-Scroll-Bar-Elements.png) ### Property: ScrollingFrame.MidImageContent ```json { "type": "Content", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Scrolling", "capabilities": [ "UI" ] } ``` Image which spans the area between [TopImage](/docs/reference/engine/classes/ScrollingFrame.md) and [BottomImage](/docs/reference/engine/classes/ScrollingFrame.md) (rotated 90° counterclockwise for a horizontal scroll bar). This image automatically scales to fill the space between the cap segments. ![Diagram showing the three image asset elements which construct a scrolling frame's scroll bar.](/assets/ui/ui-objects/ScrollingFrame-Scroll-Bar-Elements.png) ### Property: ScrollingFrame.ScrollBarImageColor3 ```json { "type": "Color3", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Scrolling", "capabilities": [ "UI" ] } ``` Determines how the scroll bar images ([TopImage](/docs/reference/engine/classes/ScrollingFrame.md), [MidImage](/docs/reference/engine/classes/ScrollingFrame.md), [BottomImage](/docs/reference/engine/classes/ScrollingFrame.md)) are colorized. When set to white, no colorization occurs. This property is useful for reusing image assets; if the source images are completely white with transparency, you can set the color of the entire scroll bar at once. ### Property: ScrollingFrame.ScrollBarImageTransparency ```json { "type": "float", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Scrolling", "capabilities": [ "UI" ] } ``` Determines the opacity of the scroll bar images ([TopImage](/docs/reference/engine/classes/ScrollingFrame.md), [MidImage](/docs/reference/engine/classes/ScrollingFrame.md), [BottomImage](/docs/reference/engine/classes/ScrollingFrame.md)). A value of `0` is completely opaque and a value of `1` is completely transparent (invisible). ### Property: ScrollingFrame.ScrollBarThickness ```json { "type": "int", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Scrolling", "capabilities": [ "UI" ] } ``` Thickness of the scroll bar in pixels; applies to both horizontal and vertical scroll bars. If set to `0`, no scroll bars are rendered. ### Property: ScrollingFrame.ScrollingDirection ```json { "type": "ScrollingDirection", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Scrolling", "capabilities": [ "UI" ] } ``` This property determines the direction(s) in which scrolling is allowed. If scrolling is disallowed in a direction, the associated scroll bar will not appear. Defaults to [ScrollingDirection.XY](/docs/reference/engine/enums/ScrollingDirection.md). ### Property: ScrollingFrame.ScrollingEnabled ```json { "type": "boolean", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Scrolling", "capabilities": [ "UI" ] } ``` Determines whether scrolling is allowed on the frame. If `false`, no scroll bars will be rendered. ### Property: ScrollingFrame.TopImage ```json { "type": "ContentId", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Scrolling", "capabilities": [ "UI" ] } ``` Image which displays on the top of a vertical scroll bar, or the left of a horizontal scroll bar (rotated 90° counterclockwise for a horizontal scroll bar). ![Diagram showing the three image asset elements which construct a scrolling frame's scroll bar.](/assets/ui/ui-objects/ScrollingFrame-Scroll-Bar-Elements.png) ### Property: ScrollingFrame.TopImageContent ```json { "type": "Content", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Scrolling", "capabilities": [ "UI" ] } ``` ### Property: ScrollingFrame.VerticalScrollBarInset ```json { "type": "ScrollBarInset", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Scrolling", "capabilities": [ "UI" ] } ``` Indicates whether [CanvasSize](/docs/reference/engine/classes/ScrollingFrame.md) is inset by [ScrollBarThickness](/docs/reference/engine/classes/ScrollingFrame.md) on the vertical axis. ### Property: ScrollingFrame.VerticalScrollBarPosition ```json { "type": "VerticalScrollBarPosition", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Scrolling", "capabilities": [ "UI" ] } ``` Indicates whether the vertical scroll bar is positioned to the left or right of the canvas. Defaults to [VerticalScrollBarPosition.Right](/docs/reference/engine/enums/VerticalScrollBarPosition.md). ## Methods ### Method: ScrollingFrame:GetScrollVelocity **Signature:** `ScrollingFrame:GetScrollVelocity(): Vector2` Returns a [Vector2](/docs/reference/engine/datatypes/Vector2.md) representing the current inertial scroll velocity after the user stops their input, for example lifts their finger off the `ScrollingFrame` on a touch-enabled device. Note that this method may only produce noticable data on an actual device or in an emulated scenario from Studio's **Device Emulator**. *Security: None · Thread Safety: Unsafe · Capabilities: UI* **Returns:** `Vector2` ### Method: ScrollingFrame:ResetScrollVelocity **Signature:** `ScrollingFrame:ResetScrollVelocity(): ()` Resets the inertial scroll velocity of the `ScrollingFrame` to `0` on both axes. *Security: None · Thread Safety: Unsafe · Capabilities: UI* **Returns:** `()` ## Inherited Members ### From [GuiObject](/docs/reference/engine/classes/GuiObject.md) -
