---@meta

---
---Provides an interface for modifying and retrieving information about the program's window.
---
---@class love.window
love.window = {}

---
---Closes the window. It can be reopened with love.window.setMode.
---
function love.window.close() end

---
---Converts a number from pixels to density-independent units.
---
---The pixel density inside the window might be greater (or smaller) than the 'size' of the window. For example on a retina screen in Mac OS X with the highdpi window flag enabled, the window may take up the same physical size as an 800x600 window, but the area inside the window uses 1600x1200 pixels. love.window.fromPixels(1600) would return 800 in that case.
---
---This function converts coordinates from pixels to the size users are expecting them to display at onscreen. love.window.toPixels does the opposite. The highdpi window flag must be enabled to use the full pixel density of a Retina screen on Mac OS X and iOS. The flag currently does nothing on Windows and Linux, and on Android it is effectively always enabled.
---
---Most LÖVE functions return values and expect arguments in terms of pixels rather than density-independent units.
---
---@overload fun(px: number, py: number):number, number
---@param pixelvalue number # A number in pixels to convert to density-independent units.
---@return number value # The converted number, in density-independent units.
function love.window.fromPixels(pixelvalue) end

---
---Gets the DPI scale factor associated with the window.
---
---The pixel density inside the window might be greater (or smaller) than the 'size' of the window. For example on a retina screen in Mac OS X with the highdpi window flag enabled, the window may take up the same physical size as an 800x600 window, but the area inside the window uses 1600x1200 pixels. love.window.getDPIScale() would return 2.0 in that case.
---
---The love.window.fromPixels and love.window.toPixels functions can also be used to convert between units.
---
---The highdpi window flag must be enabled to use the full pixel density of a Retina screen on Mac OS X and iOS. The flag currently does nothing on Windows and Linux, and on Android it is effectively always enabled.
---
---@return number scale # The pixel scale factor associated with the window.
function love.window.getDPIScale() end

---
---Gets the width and height of the desktop.
---
---@param displayindex number # The index of the display, if multiple monitors are available.

function love.window.getFullscreen() end

---
---Gets a list of supported fullscreen modes.
---
---@param displayindex number # The index of the display, if multiple monitors are available.
---@return table modes # A table of width/height pairs. (Note that this may not be in order.)
function love.window.getFullscreenModes(displayindex) end

---
---Gets the window icon.
---
---@return love.ImageData imagedata # The window icon imagedata, or nil if no icon has been set with love.window.setIcon.
function love.window.getIcon() end

---
---Gets the display mode and properties of the window.
---
---@return number width # Window width.
---@return number height # Window height.
---@return {fullscreen: boolean, fullscreentype: FullscreenType, vsync: boolean, msaa: number, resizable: boolean, borderless: boolean, centered: boolean, display: number, minwidth: number, minheight: number, highdpi: boolean, refreshrate: number, x: number, y: number, srgb: boolean} flags # Table with the window properties:
function love.window.getMode() end

---
---Gets the position of the window on the screen.
---
---The window position is in the coordinate space of the display it is currently in.
---
---@return number displayindex # The index of the display that the window is in.
function love.window.getPosition() end

---
---Gets area inside the window which is known to be unobstructed by a system title bar, the iPhone X notch, etc. Useful for making sure UI elements can be seen by the user.

---
---Checks if the game window has mouse focus.
---
---@return boolean focus # True if the window has mouse focus or false if not.
function love.window.hasMouseFocus() end

---
---Gets whether the display is allowed to sleep while the program is running.
---
---Display sleep is disabled by default. Some types of input (e.g. joystick button presses) might not prevent the display from sleeping, if display sleep is allowed.
---
---@return boolean enabled # True if system display sleep is enabled / allowed, false otherwise.
function love.window.isDisplaySleepEnabled() end

---
---Gets whether the Window is currently maximized.
---
---The window can be maximized if it is not fullscreen and is resizable, and either the user has pressed the window's Maximize button or love.window.maximize has been called.
---
---@return boolean maximized # True if the window is currently maximized in windowed mode, false otherwise.

---
---@return boolean visible # True if the window is visible or false if not.
function love.window.isVisible() end

---
---Makes the window as large as possible.
---
---This function has no effect if the window isn't resizable, since it essentially programmatically presses the window's 'maximize' button.
---
function love.window.maximize() end

---
---Minimizes the window to the system's task bar / dock.
---
function love.window.minimize() end

---
---Causes the window to request the attention of the user if it is not in the foreground.

function love.window.requestAttention(continuous) end

---
---Restores the size and position of the window if it was minimized or maximized.
---
function love.window.restore() end

---
---Sets whether the display is allowed to sleep while the program is running.
---
---Display sleep is disabled by default. Some types of input (e.g. joystick button presses) might not prevent the display from sleeping, if display sleep is allowed.
---
---@param enable boolean # True to enable system display sleep, false to disable it.
function love.window.setDisplaySleepEnabled(enable) end

---
---Enters or exits fullscreen. The display to use when entering fullscreen is chosen based on which display the window is currently in, if multiple monitors are connected.
---
---@overload fun(fullscreen: boolean, fstype: love.FullscreenType):boolean
---@param fullscreen boolean # Whether to enter or exit fullscreen mode.
---@return boolean success # True if an attempt to enter fullscreen was successful, false otherwise.

---
---Sets the display mode and properties of the window.
---
---If width or height is 0, setMode will use the width and height of the desktop. 
---
---Changing the display mode may have side effects: for example, canvases will be cleared and values sent to shaders with canvases beforehand or re-draw to them afterward if you need to.
