A `Class.VideoDisplay` is a GUI object that displays video content from a
`Class.VideoPlayer` connected via a `Class.Wire`. It functions similarly to a
`Class.ImageLabel` but is designed for video playback.


Fires after a `Class.Wire` becomes connected or disconnected, and that
`Class.Wire` is now or was previously connected to a pin on the
`Class.VideoDisplay` and to some other wirable instance.


VideoDisplay.WiringChanged

connected

Whether the instance got connected or disconnected.


The pin on the `Class.VideoDisplay` that the `Class.Wire` targets.


wire

The `Class.Wire` between the `Class.VideoDisplay` and the other
instance.


instance

The other instance that is or was connected through the `Class.Wire`.


Fires when another instance is connected to or disconnected from the
`Class.VideoDisplay` via a `Class.Wire`.


Returns an array of `Class.Wire|Wires` that are connected to the specified
pin. `Class.VideoDisplay` has one "Input" pin.


VideoDisplay:GetConnectedWires

Returns an array of `Class.Wire|Wires` that are connected to the specified
pin.


Gets the list of pins that `Class.Wire` can use in `Class.Wire.TargetName`
to connect to this instance via its `Class.Wire.TargetInstance` property.

For `Class.VideoDisplay`, this is `Input` only.


VideoDisplay:GetInputPins

An array of strings representing valid pin names.


Gets the list of pins that `Class.Wire` can use in `Class.Wire.TargetName`
to connect to this instance via its `Class.Wire.TargetInstance` property.


Gets the list of pins that `Class.Wire` can use in `Class.Wire.SourceName`
to connect to this instance via its `Class.Wire.SourceInstance` property.

For `Class.VideoDisplay`, there are none.


VideoDisplay:GetOutputPins

Gets the list of pins that `Class.Wire` can use in `Class.Wire.SourceName`
to connect to this instance via its `Class.Wire.SourceInstance` property.


VideoDisplay

Determines how the video looks when it is scaled. By default, the video
smooths out texturing when displayed on the screen larger or smaller than
its size in texture memory. When set to
`Enum.ResamplerMode.Pixelated|Enum.ResamplerMode.Pixelated`, the video
preserves the sharp edges of pixels.


VideoDisplay.ResampleMode

Selects the texture resampling mode for the `Class.VideoDisplay`.


Determines how a video texture is rendered when the UI element's aspect
ratio differs from the source video's aspect ratio.

By default, this property is `Enum.ScaleType.Stretch` which will simply
stretch/compact the video texture dimensions so it fits the UI element's
space exactly.


VideoDisplay.ScaleType

Determines how a video will scale if displayed in a UI element whose
aspect ratio differs from the source video.


VideoDisplay.TileSize

Determines how a video is colorized. When set to white, no colorization
occurs. This property is useful for reusing video assets.


VideoDisplay.VideoColor3

Determines how a rendered video will be colorized.


Allows the partial display of a video in conjunction with
`Class.VideoDisplay.VideoRectSize|VideoRectSize`. This property determines
the pixel offset (from the top-left) of the video area to be displayed.


VideoDisplay.VideoRectOffset

The offset in pixels of the sub-area of a video to be displayed.


Allows the partial display of a video in conjunction with
`Class.VideoDisplay.VideoRectOffset|VideoRectOffset`. This property
determines the pixel size of the video area to be displayed. If either
dimension is set to `0`, the entire video is displayed instead.


VideoDisplay.VideoRectSize

Determines the size in pixels of the sub-area of a video to be displayed.


Determines the alpha of a UI element's rendered video texture. A value of
`0` is completely opaque, and a value of `1` is completely transparent
(invisible).


VideoDisplay.VideoTransparency

Determines the transparency of the rendered video.


A GUI object that displays video content from a connected `Class.VideoPlayer`.


`Class.GuiObject` is an abstract class (much like `Class.BasePart`) for a 2D
user interface object. It defines all the properties relating to the display
of a graphical user interface (GUI) object such as `Class.GuiObject.Size|Size`
and `Class.GuiObject.Position|Position`. It also has some useful read‑only
properties like `Class.GuiObject.AbsolutePosition|AbsolutePosition`,
`Class.GuiObject.AbsoluteSize|AbsoluteSize`, and
`Class.GuiObject.AbsoluteRotation|AbsoluteRotation`.

To manipulate the layout of GUI objects in special ways, you can use a layout
structure such as [list/flex](/ui/list-flex-layouts) or
[grid](/ui/grid-table-layouts), and you can style them beyond their
core properties through
[appearance modifiers](/ui/appearance-modifiers).

Although it's possible to detect mouse button events on any GUI object using
`Class.GuiObject.InputBegan|InputBegan` and
`Class.GuiObject.InputEnded|InputEnded`, only `Class.ImageButton` and
`Class.TextButton` have convenient dedicated events such as
`Class.TextButton.Activated|Activated` to detect click/press.


The below example assumes it's within a GuiObject such as a `TextButton`, and
that the `Class.GuiObject.Draggable` property is set to true. It will print
the UDim2 of where the player started dragging the object from.


This event fires when a player begins dragging the object.

See also `Class.GuiObject.DragStopped`.


GuiObject.DragBegin

initialPosition

A `Datatype.UDim2` value of the position of the `Class.GuiObject`
before any drag operation began.


Fired when a player begins dragging the object.


The below example assumes it's within a GuiObject such as a `TextButton`, and
that the `Class.GuiObject.Draggable` property is set to true. It will print
the X and Y of where the player stopped dragging the GUI. For example, if the
player were to stop dragging the object at 189, 180 the below would print The
player stopped dragging the GuiObject at (189, 180)


This event fires when a player stops dragging the object.

See also `Class.GuiObject.DragBegin`.


GuiObject.DragStopped

The mouse's **X** screen location in pixels, relative to the top left
corner of the screen.


The mouse's **Y** screen location in pixels, relative to the top left
corner of the screen.


Fired when a player stops dragging the object.


The following example demonstrates one of many usage examples of handling user
input from InputBegan depending on its type.

In order for this to work as expected, it must be placed in a `LocalScript`
and a child of _gui_.


This event fires when a user begins interacting with the `Class.GuiObject`
via a Human-Computer Interface device (Mouse button down, touch begin,
keyboard button down, etc).

The `Class.UserInputService` has a similarly named event that is not
restricted to a specific UI element: `Class.UserInputService.InputBegan`.

This event will always fire regardless of game state.

See also `Class.GuiObject.InputEnded` and `Class.GuiObject.InputChanged`.


GuiObject.InputBegan

input

An `Class.InputObject`, which contains useful data for querying user
input such as the `Enum.UserInputType|type of input`,
`Enum.UserInputState|state of input`, and
`Class.InputObject.Position|screen coordinates of the input`.


Fired when a user begins interacting via a Human-Computer Interface device
(Mouse button down, touch begin, keyboard button down, etc).


The following example demonstrates one of many usage examples of handling user
input from InputChanged depending on its type.

In order for this to work as expected, it must be placed in a `LocalScript`
and a child of _gui_.


This event fires when a user changes how they're interacting via a
Human-Computer Interface device (Mouse button down, touch begin, keyboard
button down, etc).

The `Class.UserInputService` has a similarly named event that is not
restricted to a specific UI element:
`Class.UserInputService.InputChanged`.

This event will always fire regardless of game state.

See also `Class.GuiObject.InputBegan` and `Class.GuiObject.InputEnded`.


GuiObject.InputChanged

Fired when a user changes how they're interacting via a Human-Computer
Interface device (Mouse button down, touch begin, keyboard button down,
etc).


The following example demonstrates one of many usage examples of handling user
input from InputEnded depending on its type.

In order for this to work as expected, it must be placed in a `LocalScript`
and a child of _gui_.


The InputEnded event fires when a user stops interacting via a
Human-Computer Interface device (Mouse button down, touch begin, keyboard
button down, etc).

The `Class.UserInputService` has a similarly named event that is not
restricted to a specific UI element: `Class.UserInputService.InputEnded`.

This event will always fire regardless of game state.

See also `Class.GuiObject.InputBegan` and `Class.GuiObject.InputChanged`.


GuiObject.InputEnded

An `Class.InputObject`, which contains useful data for querying user
input such as the `Enum.UserInputType`, `Enum.UserInputState`, and
`Class.InputObject.Position`.


Fired when a user stops interacting via a Human-Computer Interface device
(Mouse button down, touch begin, keyboard button down, etc).


The following example prints the mouse location, in pixels, when it enters GUI
element.


The MouseEnter event fires when a user moves their mouse into a
`Class.GuiObject` element.

Please do not rely on the `x` and `y` arguments passed by this event as a
fool-proof way to determine where the user's mouse is when it enters a
GUI. These coordinates may vary even when the mouse enters the GUI via the
same edge - particularly when the mouse enters the element quickly. This
is due to the fact the coordinates indicate the position of the mouse when
the event fires rather than the exact moment the mouse enters the GUI.

This event fires even when the GUI element renders beneath another
element.

If you would like to track when a user's mouse leaves a GUI element, you
can use the `Class.GuiObject.MouseLeave` event.

##### See Also

- `Class.GuiObject.MouseLeave`
- `Class.GuiObject.MouseMoved`
- `Class.GuiObject.MouseWheelForward`
- `Class.GuiObject.MouseWheelBackward`


GuiObject.MouseEnter

The mouse's **X** screen coordinate in pixels, relative to the top
left corner of the screen.


The mouse's **Y** screen coordinate in pixels, relative to the top
left corner of the screen.


Fires when a user moves their mouse into a GUI element.


The MouseLeave event fires when a user moves their mouse out of a
`Class.GuiObject` element.

Please do not rely on the `x` and `y` arguments passed by this event as a
fool-proof way to determine where the user's mouse is when it leaves a
GUI. These coordinates may vary even when the mouse leaves the GUI via the
same edge - particularly when the mouse leaves the element quickly. This
is due to the fact the coordinates indicate the position of the mouse when
the event fires rather than the exact moment the mouse leaves the GUI.

This event fires even when the GUI element renders beneath another
element.

- `Class.GuiObject.MouseWheelBackward`


GuiObject.MouseLeave

Fires when a user moves their mouse out of a GUI element.


Fires whenever a user moves their mouse while it is inside a
`Class.GuiObject` element. It is similar to `Class.Mouse.Move`, which
fires regardless whether the user's mouse is over a GUI element.

Note, this event fires when the mouse's position is updated, therefore it
will fire repeatedly while being moved.

The `x` and `y` arguments indicate the updated screen coordinates of the
user's mouse in pixels. These can be useful to determine the mouse's
location on the GUI, screen, and delta since the mouse's previous position
if it is being tracked in a global variable.

The code below demonstrates how to determine the `Datatype.Vector2` offset
of the user's mouse relative to a GUI element:

```lua
local Players = game:GetService("Players")

local CustomScrollingFrame = script.Parent
local SubFrame = CustomScrollingFrame:FindFirstChild("SubFrame")

local mouse = Players.LocalPlayer:GetMouse()

local function getPosition(X, Y)
	local gui_X = CustomScrollingFrame.AbsolutePosition.X
	local gui_Y = CustomScrollingFrame.AbsolutePosition.Y


	local pos = Vector2.new(math.abs(X - gui_X), math.abs(Y - gui_Y - 36))
	print(pos)
end

CustomScrollingFrame.MouseMoved:Connect(getPosition)
```

Note that this event may not fire exactly when the user's mouse enters or
exits a GUI element. Therefore, the `x` and `y` arguments may not match up
perfectly to the coordinates of the GUI's edges.

- `Class.GuiObject.MouseLeave`
- `Class.GuiObject.MouseWheelForward`
- `Class.GuiObject.MouseWheelBackward`


GuiObject.MouseMoved

Fires whenever a user moves their mouse while it is inside a GUI element.


The WheelBackward event fires when a user scrolls their mouse wheel back
when the mouse is over a `Class.GuiObject` element. It is similar to
`Class.Mouse.WheelBackward`, which fires regardless whether the user's
mouse is over a GUI element.

This event fires merely as an indicator of the wheel's backward movement.
This means that the `x` and `y` mouse coordinate arguments don't change as
a result of this event. These coordinates only change when the mouse
moves, which can be tracked by the `Class.GuiObject.MouseMoved` event.

##### See Also

- `Class.GuiObject.MouseEnter`
- `Class.GuiObject.MouseLeave`
- `Class.GuiObject.MouseMoved`
- `Class.GuiObject.MouseWheelForward`


GuiObject.MouseWheelBackward

Fires when a user scrolls their mouse wheel back when the mouse is over a
GUI element.


The WheelForward event fires when a user scrolls their mouse wheel forward
when the mouse is over a `Class.GuiObject` element. It is similar to
`Class.Mouse.WheelForward`, which fires regardless whether the user's
mouse is over a GUI element.

This event fires merely as an indicator of the wheel's forward movement.
This means that the **X** and **Y** mouse coordinate arguments do not
change as a result of this event. These coordinates only change when the
mouse moves, which can be tracked by the `Class.GuiObject.MouseMoved`
event.

##### See Also

- `Class.GuiObject.MouseEnter`
- `Class.GuiObject.MouseLeave`
- `Class.GuiObject.MouseMoved`
- `Class.GuiObject.MouseWheelBackward`


GuiObject.MouseWheelForward

The **Y** coordinate of the user's mouse.


Fires when a user scrolls their mouse wheel forward when the mouse is over
a GUI element.


The following example prints a message when the user selects the object with a
gamepad.

In order for this to work as expected, it must be placed in a `LocalScript`
and a child of _gui_.


This event fires when the Gamepad selector starts focusing on the
`Class.GuiObject`.

If you want to check from the Gamepad select stops focusing on the GUI
element, you can use the `Class.GuiObject.SelectionLost` event.

When a GUI gains selection focus, the value of the
`Class.GuiService.SelectedObject|SelectedObject` property also changes to
the that gains selection. To determine which GUI gained selection, check
the value of this property.


GuiObject.SelectionGained

Fired when the GuiObject is being focused on with the Gamepad selector.


The following example prints a message when the element has its focus lost on
a gamepad.

In order for this to work as expected, it must be placed in a `LocalScript`
and a child of _gui_.


This event fires when the Gamepad selector stops focusing on the
`Class.GuiObject`.

If you want to check from the Gamepad select starts focusing on the GUI
element, you can use the `Class.GuiObject.SelectionGained` event.

When a GUI loses selection focus, the value of the
`Class.GuiService.SelectionObject|SelectionObject` property changes either
to `nil` or to the GUI element that gains selection focus. To determine
which GUI gained selection, or if no GUI is selected, check the value of
this property.


GuiObject.SelectionLost

Fired when the Gamepad selector stops focusing on the GuiObject.


This code sample allows the player to manipulate the screen position of some
UI element, like a `Frame`, by holding down on the UI element for a brief
moment. Then, the player moves their finger and releases. During the gesture
the Frame is colored blue with a white outline.


This event fires after a brief moment when the player holds their finger
on the UI element using a touch-enabled device. It fires with a table of
`Datatype.Vector2` that describe the relative screen positions of the
fingers involved in the gesture. In addition, it fires multiple times:
`Enum.UserInputState.Begin` after a brief delay,
`Enum.UserInputState.Change` if the player moves their finger during the
gesture, and finally `Enum.UserInputState.End`. The delay is platform
dependent; in Studio it is a little longer than one second.


GuiObject.TouchLongPress

touchPositions

An array of `Datatype.Vector2` that describe the **relative**
positions of the fingers involved in the gesture.


state

A `Enum.UserInputState` that describes the state of the gesture:

- Begin fires once at the beginning of the gesture (after the brief
  delay)
- Change fires if the player moves their finger while pressing down
- End fires once at the end of the gesture when they release their
  finger.


Fires when the player starts, continues and stops long-pressing the UI
element.


This code sample is meant to be placed in a `LocalScript` within an inner
`Frame` that is inside an outer `Frame`, or other `GuiObject`. It allows the
player to manipulate the position of the inner frame by moving their finger on
the outer frame.


This event fires when the player moves their finger on the UI element
using a touch-enabled device. It fires shortly before
`Class.GuiObject.TouchSwipe` would, and does not fire with
`Class.GuiObject.TouchTap`. This event is useful for allowing the player
to manipulate the position of UI elements on the screen.

This event fires with a table of `Datatype.Vector2` that describe the
relative screen positions of the fingers involved in the gesture. In
addition, it fires multiple times: `Enum.UserInputState.Begin` after a
brief delay, `Enum.UserInputState.Change` when the player moves their
finger during the gesture, and finally with `Enum.UserInputState.End`.


GuiObject.TouchPan

A Luau array of `Datatype.Vector2` objects, each indicating the
position of all the fingers involved in the gesture.


totalTranslation

Indicates how far the pan gesture has gone from its starting point.


velocity

Indicates how quickly the gesture is being performed in each
dimension.


Indicates the `Enum.UserInputState` of the gesture.


Fires when the player moves their finger on the UI element.


This code sample is meant for a `LocalScript` within an inner `Frame` that is
inside an outer `Frame`, or other `GuiObject`. It allows the player to scale
the inner frame by performing a `Class.GuiObject.TouchPinch` gesture on the
outer frame.


This event fires when the player uses two fingers to make a pinch or pull
gesture on the UI element using a touch-enabled device. A **pinch**
happens when two or more fingers move closer together, and a **pull**
happens when they move apart. This event fires in conjunction with
`Class.GuiObject.TouchPan`. This event is useful for allowing the player
to manipulate the scale (size) of UI elements on the screen, and is most
often used for zooming features.

This event fires with a table of `Datatype.Vector2` that describe the
relative screen positions of the fingers involved in the gesture. In
addition, it fires multiple times: `Enum.UserInputState.Begin` after a
brief delay, `Enum.UserInputState.Change` when the player moves a finger
during the gesture, and finally with `Enum.UserInputState.End`. It should
be noted that the scale should be used **multiplicatively**.


GuiObject.TouchPinch

A Luau array of `Datatype.Vector2` objects, each indicating the
position of all the fingers involved in the pinch gesture.


scale

A float that indicates the difference from the beginning of the pinch
gesture.


A float indicating how quickly the pinch gesture is happening.


Fires when the player performs a pinch or pull gesture using two fingers
on the UI element.


This code sample is meant for a `LocalScript` within an inner `Frame` that is
inside an outer `Frame`, or other `GuiObject`. It allows the player to rotate
the inner frame by performing a `Class.GuiObject.TouchRotate` gesture on the
outer frame.


This event fires when the player uses two fingers to make a pinch or pull
gesture on the UI element using a touch-enabled device. Rotation occurs
when the angle of the line between two fingers changes. This event fires
in conjunction with `Class.GuiObject.TouchPan`. This event is useful for
allowing the player to manipulate the rotation of UI elements on the
screen.

This event fires with a table of `Datatype.Vector2` that describe the
relative screen positions of the fingers involved in the gesture. In
addition, it fires multiple times: `Enum.UserInputState.Begin` after a
brief delay, `Enum.UserInputState.Change` when the player moves a finger
during the gesture, and finally with `Enum.UserInputState.End`.


GuiObject.TouchRotate

rotation

A float indicating how much the rotation has gone from the start of
the gesture.


A float that indicates how quickly the gesture is being performed.


Fires when the player performs a rotation gesture using two fingers on the
UI element.


This code sample will cause a `Frame` (or other `GuiObject`) to bounce when a
swipe gesture is performed on a touch-enabled device (or Studio's emulator).
Horizontal swipes will change the hue of the
`Class.GuiObject.BackgroundColor3`, while vertical swipes will change the
saturation.


This event fires when the player performs a swipe gesture on the UI
element using a touch-enabled device. It fires with the direction of the
gesture (Up, Down, Left or Right) and the number of touch points involved
in the gesture. Swipe gestures are often used to change tabs in mobile
UIs.


GuiObject.TouchSwipe

swipeDirection

A `Enum.SwipeDirection` indicating the direction of the swipe gesture
(Up, Down, Left or Right).


numberOfTouches

The number of touch points involved in the gesture (usually 1).


Fires when the player performs a swipe gesture on the UI element.


This code sample will toggle the `Class.GuiObject.BackgroundTransparency` of a
UI element, like a `Frame`, when it is tapped on a touch-enabled device.


This event fires when the player performs a tap gesture on the UI element
using a touch-enabled device. A tap is a quick single touch without any
movement involved (a longer press would fire
`Class.GuiObject.TouchLongPress`, and moving during the touch would fire
`Class.GuiObject.TouchPan` and/or `Class.GuiObject.TouchSwipe`). It fires
with a table of `Datatype.Vector2` objects that describe the relative
positions of the fingers involved in the gesture.


GuiObject.TouchTap

Fires when the player performs a tap gesture on the UI element.


This code sample demonstrates a more involved usage of TweenPosition by
detecting when the tween completes/cancels by defining a callback function. It
also prints whether the tween will play.


Smoothly moves a GUI to a new `Datatype.UDim2` position in the specified
time using the specified `Enum.EasingDirection` and `Enum.EasingStyle`.

This function will return whether the tween will play. It will not play if
another tween is acting on the `Class.GuiObject` and the override
parameter is `false`.

See also `Class.GuiObject:TweenSize()` and
`Class.GuiObject:TweenSizeAndPosition()`.


GuiObject:TweenPosition

endPosition

easingDirection

The direction in which to ease the GUI to the _endPosition_.


easingStyle

The style in which to ease the GUI to the _endPosition_.


time

How long, in seconds, the tween should take to complete.


override

Whether the tween will override an in-progress tween.


callback

A callback function to execute when the tween completes.


Smoothly moves a GUI to a new `Datatype.UDim2`.


This code sample demonstrates the usage of the `Class.GuiObject:TweenSize()`
function. It initiates an animation on the parent's `Class.GuiObject.Size`
property to `UDim2.new(0.5, 0, 0.5, 0)`, which is half the `GuiObject`'s
parent size on both axes.

Additionally, it demonstrates how the callback parameter can be used to detect
when the tween stops (whether it was cancelled by another tween or completed).


Smoothly resizes a `Class.GuiObject` to a new `Datatype.UDim2` in the
specified time using the specified `Enum.EasingDirection` and
`Enum.EasingStyle`.

This function will return whether the tween will play. Normally this will
always return `true`, but it will return `false` if another tween is
active and override is set to `false`.

See also `Class.GuiObject:TweenSize()` and
`Class.GuiObject:TweenSizeAndPosition()`.


GuiObject:TweenSize

endSize

The direction in which to ease the GUI to the _endSize_.


The style in which to ease the GUI to the _endSize_.


Smoothly resizes a `Class.GuiObject` to a new `Datatype.UDim2`.


The below example would tween a `Class.Frame` to the top left of the parent's
size and resize it down to 0.


Smoothly resizes and moves a GUI to a new `Datatype.UDim2` size and
position in the specified time using the specified `Enum.EasingDirection`
and `Enum.EasingStyle`.

This function will return whether the tween will play. Normally this will
always return `true`, but it will return `false` if another tween is
active and override is set to `false`.

See also `Class.GuiObject:TweenSize()` and
`Class.GuiObject:TweenSizeAndPosition()`.


GuiObject:TweenSizeAndPosition

The direction in which to ease the GUI to the _endSize_ and
_endPosition_.


The style in which to ease the GUI to the _endSize_ and _endPosition_.


Smoothly moves a GUI to a new size and position.


GuiObject

This code sample demonstrates the usage of the Active property as a debounce
for the Activated event.


This property determines whether the `Class.GuiObject` will sink input to
3D space, such as underlying models with a `Class.ClickDetector` class
like `Class.DragDetector`.

For `Class.GuiButton` objects (`Class.ImageButton` and
`Class.TextButton`), this property determines whether
`Class.GuiButton.Activated|Activated` fires
(`Class.GuiButton.AutoButtonColor|AutoButtonColor` will still work for
those as well). The events `Class.GuiObject.InputBegan|InputBegan`,
`Class.GuiObject.InputChanged|InputChanged`, and
`Class.GuiObject.InputEnded|InputEnded` work as normal no matter the value
of this property.


GuiObject.Active

Determines whether this UI element sinks input.


This code sample moves a UI element to different sides of the parent element.
It starts at the top-left and ends at the bottom-right. Paste into a
LocalScript in a Frame, within a ScreenGui.


This property determines the origin point of a `Class.GuiObject`, relative
to its absolute size. The origin point determines from where the element
is positioned (through `Class.GuiObject.Position`) and from which the
rendered `Class.GuiObject.Size` expands.

See [here](/ui/position-and-size#anchorpoint) for illustrated
diagrams and details.


GuiObject.AnchorPoint

Determines the origin point of a `Class.GuiObject`, relative to its
absolute size.


The following script creates an automatically-sized parent frame with
a`UIListLayout`, then it inserts several automatically-sized `TextLabel`
objects. Note how the parent `UIListLayout` automatically resizes to fit its
child content and the labels automatically resize to fit their text content.
This script can be parented to a `ScreenGui`.


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 UI object at edit or run time, and the size will
adjust to fit that content.

When `Class.GuiObject.AutomaticSize|AutomaticSize` is set to an
`Enum.AutomaticSize` value to anything other than
`Enum.AutomaticSize|None`, this UI object may resize depending on its
child content.

For more information on how to use this property and how it works, please
see [here](/ui/size-modifiers#automatic-sizing).


GuiObject.AutomaticSize

Determines whether resizing occurs based on child content.


Determines the color of the `Class.GuiObject` background.


GuiObject.BackgroundColor

This code sample causes a parent Frame to loop through all colors of the
rainbow using Color3.fromHSV.


This property determines the color of a `Class.GuiObject` background (the
fill color). If your element contains text, such as a `Class.TextBox`,
`Class.TextButton`, or `Class.TextLabel`, make sure the color of your
background contrasts the text's color.

Another property that determines the visual properties of the background
is `Class.GuiObject.BackgroundTransparency`; if this is set to `1`,
neither the background nor the border will render.

See also `Class.GuiObject.BorderColor3|BorderColor3`.


GuiObject.BackgroundColor3

Determines the `Class.GuiObject` background color.


This property determines the transparency of the `Class.GuiObject`
background and border. It does not, however, determine the transparency of
text if the GUI is a `Class.TextBox`, `Class.TextButton`, or
`Class.TextLabel`; text transparency is determined
`Class.TextBox.TextTransparency`, `Class.TextButton.TextTransparency`, and
`Class.TextLabel.TextTransparency` respectively.

If this property is set to `1`, neither the background nor the border will
render and the GUI background will be completely transparent.


GuiObject.BackgroundTransparency

Determines the transparency of the `Class.GuiObject` background and
border.


Determines the color of the `Class.GuiObject` border.


GuiObject.BorderColor

This code sample causes the border of a parent GuiObject to highlight when the
user hovers their mouse over the element.


Determines the color of the `Class.GuiObject` rectangular border (also
known as the stroke color). This is separate from the object's
`Class.GuiObject.BackgroundColor3`. You will not be able to see the
object's border if its `Class.GuiObject.BorderSizePixel` property is set
to `0`.

Note that the `Class.UIStroke` component allows for more advanced border
effects.


GuiObject.BorderColor3

This property determines in what manner the `Class.GuiObject` border is
laid out relative to its dimensions using the enum of the same name,
`Enum.BorderMode`.

Note that `Class.UIStroke` can override this property and allow for more
advanced border effects.


GuiObject.BorderMode

Determines in what manner the `Class.GuiObject` border is laid out
relative to its dimensions.


This property determines how wide the `Class.GuiObject` border renders, in
pixels. Setting this to 0 disables the border altogether.

Note that `Class.UIStroke` can override this property and allow for more
advanced border effects.


GuiObject.BorderSizePixel

Determines the pixel width of the `Class.GuiObject` border.


An abstract class for all 2D user interface objects.
