Methods

function Window:close()

Close the window

function Window:on_close(cb: fun())

Execute a function when the window is closed.

Parameter	Type	Description
cb	fun()

function Window:move(opts?: MoveOpts, cb?: fun())

Move a window to a specific position.
Calling this function will cancel any existing move operations.
This means you can call this function with no arguments to stop moving a window.

Parameter	Type	Description
opts?	MoveOpts
cb?	fun()	Called when the window finished moving.

function Window:fade(opts?: FadeOpts, cb?: fun())

Change the opacity of a window
For a window's opacity to be changeable, it must have been created with
`transparent = true` (this is done automatically in some cases, see SpawnWindowOpts.transparent).

Parameter	Type	Description
opts?	FadeOpts
cb?	fun()	Called when the window's opacity has finished changing.

function Window:set_visible(visible: boolean)

Set the visibility of a window.
Making a window invisible instead of closing it can be a good idea if you want to use it again.
Making a window invisible will stop the user from interacting with it, but e.g. video windows
will continue to play, so you should consider calling VideoWindow:pause(). Always remember
to close windows that you are no longer using.

Parameter	Type	Description
visible	boolean

function Window:set_title(title: string?)

Set the text displayed in the header.

Parameter	Type	Description
title	string?

MoveOpts

Field	Type	Description
x?	Coord	The horizontal coordinate to move the window to (by default, the window will not be moved horizontally).
y?	Coord	The vertical coordinate to move the window to.
anchor?	Anchor	Where to place the window relative to the specified coordinates. By default, "top-left" is used, meaning that the top-left corner of the window is placed at the specified coordinates.
relative?	boolean	If true, then `x` and `y` are considered to be relative to the current position of the window. By default, this is false.
duration?	number	How long the movement should take. By default, the move happens instantly.
easing?	Easing	How the movement is animated.

FadeOpts

Fields

Field	Type	Description
opacity	number	The opacity to transition to. Between 0 and 1, where 0 is transparent and 1 is opaque.
duration?	number	How long the transition should take. By default, the transition happens instantly.
easing?	Easing	How the transition is animated.

Parameter	Type	Description
loop	any

PromptWindow extends Window

Fields

Field	Type	Description
type	"'prompt'"
title?	string
text?	string

Call a function every time the user submits a value.

Parameter	Type	Description
cb	fun(text: string)	A function that takes the value that the user has submitted.

tags?	string[]	If specified, only media with these tags will be included in the result.

SpawnWindowOpts

Options that can be passed into any of spawn_image_popup(), spawn_video_popup(), spawn_prompt() and spawn_choice().

Fields

Field	Type	Description
x?	Coord	The horizontal coordinate to spawn the window at. By default, the coordinates of the window will be chosen at random, ensuring that the window remains entirely visible.
y?	Coord	The vertical coordinate to spawn the window at.
anchor?	Anchor	Where to place the window relative to the specified coordinates. By default, "top-left" is used, meaning that the top-left corner of the window is placed at the specified coordinates.
width?	Coord	The width of the window. Defaults to the width of the image, or a third of the monitor width if the image is too big.
height?	Coord	The height of the window. Defaults to the height of the image, or a third of the monitor height if the image is too big.
monitor?	Monitor	The monitor to spawn the window on. By default, chooses a monitor at random.
decorations?	boolean	Whether to spawn the window with a header and border (defaults to true). Note that windows without a header will not be able to be closed manually by the user.
title?	string	The text displayed in the header. Can be set dynamically using `Window:set_title()`. If `decorations` is false, this will be ignored.
closeable?	boolean	Whether the header should include a close button. Defaults to true. If this is false, then the user will not be able to close the window manually. If `decorations` is false, this will be ignored.
visible?	boolean	Whether to make the window start off visible (defaults to true). See `Window:set_visible()`.
opacity?	number	A number between 0 and 1, where 0 is fully transparent and 1 is opaque. Use [Window:fade()](lua::Window.fade) to set this value.
transparent?	boolean	Setting this to true allows the window to become transparent. This is set to `true` automatically if `opacity` is less than 1, or the image or video that this window contains is transparent, or `background_color` has an alpha less than 1. Set this to `true` if the opacity is 1 to begin with, but you want to use [Window:fade()](lua::Window.fade) to change it later. Set it to `false` explicitly if an image or video is transparent but you want to make the window opaque.
background_color?	string	The background colour of the window as a hex string. Accepts `"#rrggbb"` (opaque) or `"#rrggbbaa"` (with alpha). For prompt, choice and text windows this sets the panel fill colour; for image and video windows it sets the colour shown in transparent areas. If the alpha is less than 1, the window is automatically made transparent. When not set, the default egui light-theme background (`"#f8f8f8"`) is used for prompt/choice windows, text windows default to a fully transparent background, and transparent areas on image/video windows fall back to the `transparent` flag behaviour.

SpawnImageOpts extends SpawnWindowOpts

Options for `spawn_image()`.

SpawnVideoOpts extends SpawnWindowOpts

Options for `spawn_video()`.

Fields

Field	Type	Description
loop?	boolean	Whether to loop the video (defaults to true). If false, the window will be closed when the video ends.
audio?	boolean	Whether to play the video's audio (if there is any). Defaults to true.

PlayAudioOpts

Fields

Field	Type	Description
loop	boolean	Whether to loop the audio. If true, the audio will loop forever until you stop it.

AudioHandle

Fields

Field	Type	Description
id	number	A unique identifier for the audio handle.
audio	Audio	The audio file that is being played.

Methods

function AudioHandle:on_finish(cb: fun())

Run a function when an audio track finishes. If the audio file is set to loop, this will be
called every time the audio file loops.

Parameter	Type	Description
cb	fun()

function AudioHandle:pause()

Pause the audio track.

function AudioHandle:play()

Resume the audio track.

SetWallpaperOpts

Fields

Field	Type	Description

Options that can be passed into `spawn_choice()`.

Fields

Field	Type	Description
text?	string
options	{ id: string, label: string }[]	The list of options, which determine the buttons to present to the user. Only the label is displayed, the id is used in `on_select()`.

SpawnTextOpts extends SpawnWindowOpts

Options for `spawn_text_popup()`. If `width`/`height` are omitted, the window is sized to fit the text at the chosen `font_size` (wrapping rather than shrinking the font if it would otherwise be wider than a third of the monitor's width) — similar in spirit to how `spawn_image_popup()`/`spawn_video_popup()` size themselves from the media's dimensions.

Fields

Field	Type	Description
font?	TextFont	Which bundled font to use. Defaults to `"default"`.
font_size?	FontSize	The font size. Defaults to 32.
color?	string	The text colour as a hex string (`"#rrggbb"` or `"#rrggbbaa"`). Defaults to black.
bold?	boolean	Whether to render the text in (synthetic) bold. Defaults to false.
align?	"left" | "center" | "right"	Horizontal alignment of the text. Defaults to `"center"`. Text is always centered vertically.
border_color?	string	Outline colour for the text, as a hex string. If set, the text is drawn with a stroke in this colour — useful for keeping text legible against a transparent or unpredictable background.
border_width?	number	The width of the text outline, in pixels. Defaults to 2. Only used if `border_color` is set.

Notification

Fields

Field	Type	Description
summary?	string
body	string

Timer

Fields

Field	Type	Description
duration	number

Methods

function Timer:stop()

Stop a timer from running

Interval

Fields

Field	Type	Description

Parameter	Type	Description
duration	number

Monitor

Fields

Field	Type	Description
id	number
primary	boolean

Aliases

MediaType

"image""video""audio"

Coord

Either a coordinate in pixels, or a percentage of the screen width/height.

number | { percent: number }

Anchor

"top-left""center""bottom-right"

Easing

"linear""ease_in""ease_out""ease_in_out"

TextFont

"default" Ubuntu-Light, matching the window header/chrome. The default."mono" A monospace/typewriter font (bundled with egui, at no extra cost)."display" A bold, high-impact font intended for emphasis/title-style text.

FontSize

A font size in points, or a percentage of the monitor's height (e.g. `{ percent = 3 }` for 3% of the screen height) — useful for text that should occupy roughly the same proportion of the screen regardless of resolution. Unlike `width`/`height`/`opacity`, there's no natural "100%" reference point for a font size (100% would mean text as tall as the entire screen), so percentages here are typically small (low single digits).

number | { percent: number }
