BrowserWindow

Create and control browser windows.

// In the main process.
const {BrowserWindow} = require('electron')

// Or use `remote` from the renderer process.
// const {BrowserWindow} = require('electron').remote

let win = new BrowserWindow({width: 800, height: 600})
win.on('closed', () => {
  win = null
})

win.loadURL('https://github.com')

Frameless window

To create a window without chrome, or a transparent window in arbitrary shape, you can use the Frameless Window API.

Showing window gracefully

When loading a page in window directly, users will see the progress of loading page, which is not good experience for native app. To make the window display without visual flash, there are two solutions for different situations.

Using ready-to-show event

While loading the page, the ready-to-show event will be emitted when renderer process has done drawing for the first time, showing window after this event will have no visual flash:

const {BrowserWindow} = require('electron')
let win = new BrowserWindow({show: false})
win.once('ready-to-show', () => {
  win.show()
})

This is event is usually emitted after the did-finish-load event, but for pages with many remote resources, it may be emitted before the did-finish-load event.

Setting backgroundColor

For a complex app, the ready-to-show event could be emitted too late, making the app feel slow. In this case, it is recommended to show the window immediately, and use a backgroundColor close to your app's background:

const {BrowserWindow} = require('electron')

let win = new BrowserWindow({backgroundColor: '#2e2c29'})
win.loadURL('https://github.com')

Note that even for apps that use ready-to-show event, it is still recommended to set backgroundColor to make app feel more native.

Parent and child windows

By using parent option, you can create child windows:

const {BrowserWindow} = require('electron')

let top = new BrowserWindow()
let child = new BrowserWindow({parent: top})
child.show()
top.show()

The child window will always show on top of the top window.

Modal windows

A modal window is a child window that disables parent window, to create a modal window, you have to set both parent and modal options:

const {BrowserWindow} = require('electron')

let child = new BrowserWindow({parent: top, modal: true, show: false})
child.loadURL('https://github.com')
child.once('ready-to-show', () => {
  child.show()
})

Platform notices

• On macOS the child windows will keep the relative position to parent window when parent window moves, while on Windows and Linux child windows will not move.
• On Windows it is not supported to change parent window dynamically.
• On Linux the type of modal windows will be changed to dialog.
• On Linux many desktop environments do not support hiding a modal window.

Class: BrowserWindow

BrowserWindow is an EventEmitter.

It creates a new BrowserWindow with native properties as set by the options.

new BrowserWindow([options])

• options Object
  • width Integer - Window's width in pixels. Default is 800.
  • height Integer - Window's height in pixels. Default is 600.
  • x Integer (required if y is used) - Window's left offset from screen. Default is to center the window.
  • y Integer (required if x is used) - Window's top offset from screen. Default is to center the window.
  • useContentSize Boolean - The width and height would be used as web page's size, which means the actual window's size will include window frame's size and be slightly larger. Default is false.
  • center Boolean - Show window in the center of the screen.
  • minWidth Integer - Window's minimum width. Default is 0.
  • minHeight Integer - Window's minimum height. Default is 0.
  • maxWidth Integer - Window's maximum width. Default is no limit.
  • maxHeight Integer - Window's maximum height. Default is no limit.
  • resizable Boolean - Whether window is resizable. Default is true.
  • movable Boolean - Whether window is movable. This is not implemented on Linux. Default is true.
  • minimizable Boolean - Whether window is minimizable. This is not implemented on Linux. Default is true.
  • maximizable Boolean - Whether window is maximizable. This is not implemented on Linux. Default is true.
  • closable Boolean - Whether window is closable. This is not implemented on Linux. Default is true.
  • focusable Boolean - Whether the window can be focused. Default is true. On Windows setting focusable: false also implies setting skipTaskbar: true. On Linux setting focusable: false makes the window stop interacting with wm, so the window will always stay on top in all workspaces.
  • alwaysOnTop Boolean - Whether the window should always stay on top of other windows. Default is false.
  • fullscreen Boolean - Whether the window should show in fullscreen. When explicitly set to false the fullscreen button will be hidden or disabled on macOS. Default is false.
  • fullscreenable Boolean - Whether the window can be put into fullscreen mode. On macOS, also whether the maximize/zoom button should toggle full screen mode or maximize window. Default is true.
  • skipTaskbar Boolean - Whether to show the window in taskbar. Default is false.
  • kiosk Boolean - The kiosk mode. Default is false.
  • title String - Default window title. Default is "Electron".
  • icon NativeImage - The window icon. On Windows it is recommended to use ICO icons to get best visual effects, you can also leave it undefined so the executable's icon will be used.
  • show Boolean - Whether window should be shown when created. Default is true.
  • frame Boolean - Specify false to create a Frameless Window. Default is true.
  • parent BrowserWindow - Specify parent window. Default is null.
  • modal Boolean - Whether this is a modal window. This only works when the window is a child window. Default is false.
  • acceptFirstMouse Boolean - Whether the web view accepts a single mouse-down event that simultaneously activates the window. Default is false.
  • disableAutoHideCursor Boolean - Whether to hide cursor when typing. Default is false.
  • autoHideMenuBar Boolean - Auto hide the menu bar unless the Alt key is pressed. Default is false.
  • enableLargerThanScreen Boolean - Enable the window to be resized larger than screen. Default is false.
  • backgroundColor String - Window's background color as Hexadecimal value, like #66CD00 or #FFF or #80FFFFFF (alpha is supported). Default is #FFF (white).
  • hasShadow Boolean - Whether window should have a shadow. This is only implemented on macOS. Default is true.
  • darkTheme Boolean - Forces using dark theme for the window, only works on some GTK+3 desktop environments. Default is false.
  • transparent Boolean - Makes the window transparent. Default is false.
  • type String - The type of window, default is normal window. See more about this below.
  • titleBarStyle String - The style of window title bar. See more about this below.
  • thickFrame Boolean - Use WS_THICKFRAME style for frameless windows on Windows, which adds standard window frame. Setting it to false will remove window shadow and window animations. Default is true.
  • webPreferences Object - Settings of web page's features. See more about this below.

When setting minimum or maximum window size with minWidth/maxWidth/ minHeight/maxHeight, it only constrains the users. It won't prevent you from passing a size that does not follow size constraints to setBounds/setSize or to the constructor of BrowserWindow.

The possible values and behaviors of the type option are platform dependent. Possible values are:

• On Linux, possible types are desktop, dock, toolbar, splash, notification.
• On macOS, possible types are desktop, textured.
  • The textured type adds metal gradient appearance (NSTexturedBackgroundWindowMask).
  • The desktop type places the window at the desktop background window level (kCGDesktopWindowLevel - 1). Note that desktop window will not receive focus, keyboard or mouse events, but you can use globalShortcut to receive input sparingly.
• On Windows, possible type is toolbar.

The titleBarStyle option is only supported on macOS 10.10 Yosemite and newer. Possible values are:

• default or not specified, results in the standard gray opaque Mac title bar.
• hidden results in a hidden title bar and a full size content window, yet the title bar still has the standard window controls ("traffic lights") in the top left.
• hidden-inset results in a hidden title bar with an alternative look where the traffic light buttons are slightly more inset from the window edge.

The webPreferences option is an object that can have the following properties:

• nodeIntegration Boolean - Whether node integration is enabled. Default is true.
• preload String - Specifies a script that will be loaded before other scripts run in the page. This script will always have access to node APIs no matter whether node integration is turned on or off. The value should be the absolute file path to the script. When node integration is turned off, the preload script can reintroduce Node global symbols back to the global scope. See example here.
• session Session - Sets the session used by the page. Instead of passing the Session object directly, you can also choose to use the partition option instead, which accepts a partition string. When both session and partition are provided, session will be preferred. Default is the default session.
• partition String - Sets the session used by the page according to the session's partition string. If partition starts with persist:, the page will use a persistent session available to all pages in the app with the same partition. If there is no persist: prefix, the page will use an in-memory session. By assigning the same partition, multiple pages can share the same session. Default is the default session.
• zoomFactor Number - The default zoom factor of the page, 3.0 represents 300%. Default is 1.0.
• javascript Boolean - Enables JavaScript support. Default is true.
• webSecurity Boolean - When false, it will disable the same-origin policy (usually using testing websites by people), and set allowDisplayingInsecureContent and allowRunningInsecureContent to true if these two options are not set by user. Default is true.
• allowDisplayingInsecureContent Boolean - Allow an https page to display content like images from http URLs. Default is false.
• allowRunningInsecureContent Boolean - Allow an https page to run JavaScript, CSS or plugins from http URLs. Default is false.
• images Boolean - Enables image support. Default is true.
• textAreasAreResizable Boolean - Make TextArea elements resizable. Default is true.
• webgl Boolean - Enables WebGL support. Default is true.
• webaudio Boolean - Enables WebAudio support. Default is true.

Instance Events

Objects created with new BrowserWindow emit the following events:

Note: Some events are only available on specific operating systems and are labeled as such.

Event: 'page-title-updated'

Returns:

• event Event

Emitted when the document changed its title, calling event.preventDefault() will prevent the native window's title from changing.

Event: 'close'

Returns:

• event Event

Emitted when the window is going to be closed. It's emitted before the beforeunload and unload event of the DOM. Calling event.preventDefault() will cancel the close.

Usually you would want to use the beforeunload handler to decide whether the window should be closed, which will also be called when the window is reloaded. In Electron, returning any value other than undefined would cancel the close. For example:

window.onbeforeunload = (e) => {
  console.log('I do not want to be closed')

  // Unlike usual browsers that a message box will be prompted to users, returning
  // a non-void value will silently cancel the close.
  // It is recommended to use the dialog API to let the user confirm closing the
  // application.
  e.returnValue = false
}

Event: 'closed'

Emitted when the window is closed. After you have received this event you should remove the reference to the window and avoid using it any more.

Event: 'unresponsive'

Emitted when the web page becomes unresponsive.

Event: 'responsive'

Emitted when the unresponsive web page becomes responsive again.

Event: 'blur'

Emitted when the window loses focus.

Event: 'focus'

Emitted when the window gains focus.

Event: 'show'

Emitted when the window is shown.

Event: 'hide'

Emitted when the window is hidden.

Event: 'ready-to-show'

Emitted when the web page has been rendered and window can be displayed without a visual flash.

Event: 'maximize'

Emitted when window is maximized.

Event: 'unmaximize'

Emitted when the window exits from a maximized state.

Event: 'minimize'

Emitted when the window is minimized.

Event: 'restore'

Emitted when the window is restored from a minimized state.

Event: 'resize'

Emitted when the window is being resized.

Event: 'move'

Emitted when the window is being moved to a new position.

Note: On macOS this event is just an alias of moved.

Event: 'moved' macOS

• command String

Emitted when an App Command is invoked. These are typically related to keyboard media keys or browser commands, as well as the "Back" button built into some mice on Windows.

Commands are lowercased, underscores are replaced with hyphens, and the APPCOMMAND_ prefix is stripped off. e.g. APPCOMMAND_BROWSER_BACKWARD is emitted as browser-backward.

const {BrowserWindow} = require('electron')
let win = new BrowserWindow()
win.on('app-command', (e, cmd) => {
  // Navigate the window back when the user hits their mouse back button
  if (cmd === 'browser-backward' && win.webContents.canGoBack()) {
    win.webContents.goBack()

Static Methods

The BrowserWindow class has the following static methods:

BrowserWindow.getAllWindows()

Returns an array of all opened browser windows.

BrowserWindow.getFocusedWindow()

BrowserWindow.fromId(id)

• id Integer

Find a window according to its ID.

BrowserWindow.addDevToolsExtension(path)

• path String

Adds DevTools extension located at path, and returns extension's name.

The extension will be remembered so you only need to call this API once, this API is not for programming use. If you try to add an extension that has already been loaded, this method will not return and instead log a warning to the console.

The method will also not return if the extension's manifest is missing or incomplete.

Note: This API cannot be called before the ready event of the app module is emitted.

BrowserWindow.removeDevToolsExtension(name)

• name String

Remove a DevTools extension by name.

Note: This API cannot be called before the ready event of the app module is emitted.

BrowserWindow.getDevToolsExtensions()

Returns an Object where the keys are the extension names and each value is an Object containing name and version properties.

To check if a DevTools extension is installed you can run the following:

const {BrowserWindow} = require('electron')

let installed = BrowserWindow.getDevToolsExtensions().hasOwnProperty('devtron')
console.log(installed)

Note: This API cannot be called before the ready event of the app module is emitted.

Instance Properties

Objects created with new BrowserWindow have the following properties:

const {BrowserWindow} = require('electron')
// In this example `win` is our instance
let win = new BrowserWindow({width: 800, height: 600})
win.loadURL('https://github.com')

win.webContents

The WebContents object this window owns. All web page related events and operations will be done via it.

See the webContents documentation for its methods and events.

The unique ID of the window.

Instance Methods

Objects created with new BrowserWindow have the following instance methods:

Note: Some methods are only available on specific operating systems and are labeled as such.

This will make a window maintain an aspect ratio. The extra size allows a developer to have space, specified in pixels, not included within the aspect ratio calculations. This API already takes into account the difference between a window's size and its content size.

Consider a normal window with an HD video player and associated controls. Perhaps there are 15 pixels of controls on the left edge, 25 pixels of controls on the right edge and 50 pixels of controls below the player. In order to maintain a 16:9 aspect ratio (standard aspect ratio for HD @1920x1080) within the player itself we would call this function with arguments of 16/9 and [ 40, 50 ]. The second argument doesn't care where the extra width and height are within the content view--only that they exist. Just sum any extra width and height areas you have within the overall content view.
