# BrowserWindow
|
||
|
||
> Create and control browser windows.
|
||
|
||
Process: [Main](../glossary.md#main-process)
|
||
|
||
```javascript
|
||
// 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
|
||
})
|
||
|
||
// Load a remote URL
|
||
win.loadURL('https://github.com')
|
||
|
||
// Or load a local HTML file
|
||
win.loadURL(`file://${__dirname}/app/index.html`)
|
||
```
|
||
|
||
## Frameless window
|
||
|
||
To create a window without chrome, or a transparent window in arbitrary shape,
|
||
you can use the [Frameless Window](frameless-window.md) API.
|
||
|
||
## Showing window gracefully
|
||
|
||
When loading a page in the window directly, users may see the page load incrementally, which is not a good experience for a 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 the renderer
|
||
process has rendered the page for the first time if the window has not been shown yet. Showing
|
||
the window after this event will have no visual flash:
|
||
|
||
```javascript
|
||
const { BrowserWindow } = require('electron')
|
||
let win = new BrowserWindow({ show: false })
|
||
win.once('ready-to-show', () => {
|
||
win.show()
|
||
})
|
||
```
|
||
|
||
This 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:
|
||
|
||
```javascript
|
||
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:
|
||
|
||
```javascript
|
||
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:
|
||
|
||
```javascript
|
||
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()
|
||
})
|
||
```
|
||
|
||
### Page visibility
|
||
|
||
The [Page Visibility API][page-visibility-api] works as follows:
|
||
|
||
* On all platforms, the visibility state tracks whether the window is
|
||
hidden/minimized or not.
|
||
* Additionally, on macOS, the visibility state also tracks the window
|
||
occlusion state. If the window is occluded (i.e. fully covered) by another
|
||
window, the visibility state will be `hidden`. On other platforms, the
|
||
visibility state will be `hidden` only when the window is minimized or
|
||
explicitly hidden with `win.hide()`.
|
||
* If a `BrowserWindow` is created with `show: false`, the initial visibility
|
||
state will be `visible` despite the window actually being hidden.
|
||
* If `backgroundThrottling` is disabled, the visibility state will remain
|
||
`visible` even if the window is minimized, occluded, or hidden.
|
||
|
||
It is recommended that you pause expensive operations when the visibility
|
||
state is `hidden` in order to minimize power consumption.
|
||
|
||
### Platform notices
|
||
|
||
* On macOS modal windows will be displayed as sheets attached to the parent window.
|
||
* 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
|
||
|
||
> Create and control browser windows.
|
||
|
||
Process: [Main](../glossary.md#main-process)
|
||
|
||
`BrowserWindow` is an
|
||
[EventEmitter](https://nodejs.org/api/events.html#events_class_events_eventemitter).
|
||
|
||
It creates a new `BrowserWindow` with native properties as set by the `options`.
|
||
|
||
### `new BrowserWindow([options])`
|
||
|
||
* `options` Object (optional)
|
||
* `width` Integer (optional) - Window's width in pixels. Default is `800`.
|
||
* `height` Integer (optional) - Window's height in pixels. Default is `600`.
|
||
* `x` Integer (optional) (**required** if y is used) - Window's left offset from screen.
|
||
Default is to center the window.
|
||
* `y` Integer (optional) (**required** if x is used) - Window's top offset from screen.
|
||
Default is to center the window.
|
||
* `useContentSize` Boolean (optional) - 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 (optional) - Show window in the center of the screen.
|
||
* `minWidth` Integer (optional) - Window's minimum width. Default is `0`.
|
||
* `minHeight` Integer (optional) - Window's minimum height. Default is `0`.
|
||
* `maxWidth` Integer (optional) - Window's maximum width. Default is no limit.
|
||
* `maxHeight` Integer (optional) - Window's maximum height. Default is no limit.
|
||
* `resizable` Boolean (optional) - Whether window is resizable. Default is `true`.
|
||
* `movable` Boolean (optional) - Whether window is movable. This is not implemented
|
||
on Linux. Default is `true`.
|
||
* `minimizable` Boolean (optional) - Whether window is minimizable. This is not
|
||
implemented on Linux. Default is `true`.
|
||
* `maximizable` Boolean (optional) - Whether window is maximizable. This is not
|
||
implemented on Linux. Default is `true`.
|
||
* `closable` Boolean (optional) - Whether window is closable. This is not implemented
|
||
on Linux. Default is `true`.
|
||
* `focusable` Boolean (optional) - 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 (optional) - Whether the window should always stay on top of
|
||
other windows. Default is `false`.
|
||
* `fullscreen` Boolean (optional) - 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 (optional) - 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`.
|
||
* `simpleFullscreen` Boolean (optional) - Use pre-Lion fullscreen on macOS. Default is `false`.
|
||
* `skipTaskbar` Boolean (optional) - Whether to show the window in taskbar. Default is
|
||
`false`.
|
||
* `kiosk` Boolean (optional) - The kiosk mode. Default is `false`.
|
||
* `title` String (optional) - Default window title. Default is `"Electron"`.
|
||
* `icon` ([NativeImage](native-image.md) | String) (optional) - 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 (optional) - Whether window should be shown when created. Default is
|
||
`true`.
|
||
* `frame` Boolean (optional) - Specify `false` to create a
|
||
[Frameless Window](frameless-window.md). Default is `true`.
|
||
* `parent` BrowserWindow (optional) - Specify parent window. Default is `null`.
|
||
* `modal` Boolean (optional) - Whether this is a modal window. This only works when the
|
||
window is a child window. Default is `false`.
|
||
* `acceptFirstMouse` Boolean (optional) - Whether the web view accepts a single
|
||
mouse-down event that simultaneously activates the window. Default is
|
||
`false`.
|
||
* `disableAutoHideCursor` Boolean (optional) - Whether to hide cursor when typing.
|
||
Default is `false`.
|
||
* `autoHideMenuBar` Boolean (optional) - Auto hide the menu bar unless the `Alt`
|
||
key is pressed. Default is `false`.
|
||
* `enableLargerThanScreen` Boolean (optional) - Enable the window to be resized larger
|
||
than screen. Default is `false`.
|
||
* `backgroundColor` String (optional) - Window's background color as a hexadecimal value,
|
||
like `#66CD00` or `#FFF` or `#80FFFFFF` (alpha is supported). Default is
|
||
`#FFF` (white).
|
||
* `hasShadow` Boolean (optional) - Whether window should have a shadow. This is only
|
||
implemented on macOS. Default is `true`.
|
||
* `opacity` Number (optional) - Set the initial opacity of the window, between 0.0 (fully
|
||
transparent) and 1.0 (fully opaque). This is only implemented on Windows and macOS.
|
||
* `darkTheme` Boolean (optional) - Forces using dark theme for the window, only works on
|
||
some GTK+3 desktop environments. Default is `false`.
|
||
* `transparent` Boolean (optional) - Makes the window [transparent](frameless-window.md).
|
||
Default is `false`.
|
||
* `type` String (optional) - The type of window, default is normal window. See more about
|
||
this below.
|
||
* `titleBarStyle` String (optional) - The style of window title bar.
|
||
Default is `default`. Possible values are:
|
||
* `default` - 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.
|
||
* `hiddenInset` - Results in a hidden title bar with an alternative look
|
||
where the traffic light buttons are slightly more inset from the window edge.
|
||
* `customButtonsOnHover` Boolean (optional) - Draw custom close, minimize,
|
||
and full screen buttons on macOS frameless windows. These buttons will not
|
||
display unless hovered over in the top left of the window. These custom
|
||
buttons prevent issues with mouse events that occur with the standard
|
||
window toolbar buttons. **Note:** This option is currently experimental.
|
||
* `fullscreenWindowTitle` Boolean (optional) - Shows the title in the
|
||
title bar in full screen mode on macOS for all `titleBarStyle` options.
|
||
Default is `false`.
|
||
* `thickFrame` Boolean (optional) - 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`.
|
||
* `vibrancy` String (optional) - Add a type of vibrancy effect to the window, only on
|
||
macOS. Can be `appearance-based`, `light`, `dark`, `titlebar`, `selection`,
|
||
`menu`, `popover`, `sidebar`, `medium-light` or `ultra-dark`. Please note that
|
||
using `frame: false` in combination with a vibrancy value requires that you use a
|
||
non-default `titleBarStyle` as well.
|
||
* `zoomToPageWidth` Boolean (optional) - Controls the behavior on macOS when
|
||
option-clicking the green stoplight button on the toolbar or by clicking the
|
||
Window > Zoom menu item. If `true`, the window will grow to the preferred
|
||
width of the web page when zoomed, `false` will cause it to zoom to the
|
||
width of the screen. This will also affect the behavior when calling
|
||
`maximize()` directly. Default is `false`.
|
||
* `tabbingIdentifier` String (optional) - Tab group name, allows opening the
|
||
window as a native tab on macOS 10.12+. Windows with the same tabbing
|
||
identifier will be grouped together. This also adds a native new tab button
|
||
to your window's tab bar and allows your `app` and window to receive the
|
||
`new-window-for-tab` event.
|
||
* `webPreferences` Object (optional) - Settings of web page's features.
|
||
* `devTools` Boolean (optional) - Whether to enable DevTools. If it is set to `false`, can not use `BrowserWindow.webContents.openDevTools()` to open DevTools. Default is `true`.
|
||
* `nodeIntegration` Boolean (optional) - Whether node integration is enabled. Default
|
||
is `true`.
|
||
* `nodeIntegrationInWorker` Boolean (optional) - Whether node integration is
|
||
enabled in web workers. Default is `false`. More about this can be found
|
||
in [Multithreading](../tutorial/multithreading.md).
|
||
* `preload` String (optional) - 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](process.md#event-loaded).
|
||
* `sandbox` Boolean (optional) - If set, this will sandbox the renderer
|
||
associated with the window, making it compatible with the Chromium
|
||
OS-level sandbox and disabling the Node.js engine. This is not the same as
|
||
the `nodeIntegration` option and the APIs available to the preload script
|
||
are more limited. Read more about the option [here](sandbox-option.md).
|
||
**Note:** This option is currently experimental and may change or be
|
||
removed in future Electron releases.
|
||
* `session` [Session](session.md#class-session) (optional) - 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 (optional) - 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.
|
||
* `affinity` String (optional) - When specified, web pages with the same
|
||
`affinity` will run in the same renderer process. Note that due to reusing
|
||
the renderer process, certain `webPreferences` options will also be shared
|
||
between the web pages even when you specified different values for them,
|
||
including but not limited to `preload`, `sandbox` and `nodeIntegration`.
|
||
So it is suggested to use exact same `webPreferences` for web pages with
|
||
the same `affinity`. _This property is experimental_
|
||
* `zoomFactor` Number (optional) - The default zoom factor of the page, `3.0` represents
|
||
`300%`. Default is `1.0`.
|
||
* `javascript` Boolean (optional) - Enables JavaScript support. Default is `true`.
|
||
* `webSecurity` Boolean (optional) - When `false`, it will disable the
|
||
same-origin policy (usually using testing websites by people), and set
|
||
`allowRunningInsecureContent` to `true` if this options has not been set
|
||
by user. Default is `true`.
|
||
* `allowRunningInsecureContent` Boolean (optional) - Allow an https page to run
|
||
JavaScript, CSS or plugins from http URLs. Default is `false`.
|
||
* `images` Boolean (optional) - Enables image support. Default is `true`.
|
||
* `textAreasAreResizable` Boolean (optional) - Make TextArea elements resizable. Default
|
||
is `true`.
|
||
* `webgl` Boolean (optional) - Enables WebGL support. Default is `true`.
|
||
* `webaudio` Boolean (optional) - Enables WebAudio support. Default is `true`.
|
||
* `plugins` Boolean (optional) - Whether plugins should be enabled. Default is `false`.
|
||
* `experimentalFeatures` Boolean (optional) - Enables Chromium's experimental features.
|
||
Default is `false`.
|
||
* `scrollBounce` Boolean (optional) - Enables scroll bounce (rubber banding) effect on
|
||
macOS. Default is `false`.
|
||
* `enableBlinkFeatures` String (optional) - A list of feature strings separated by `,`, like
|
||
`CSSVariables,KeyboardEventKey` to enable. The full list of supported feature
|
||
strings can be found in the [RuntimeEnabledFeatures.json5][runtime-enabled-features]
|
||
file.
|
||
* `disableBlinkFeatures` String (optional) - A list of feature strings separated by `,`,
|
||
like `CSSVariables,KeyboardEventKey` to disable. The full list of supported
|
||
feature strings can be found in the
|
||
[RuntimeEnabledFeatures.json5][runtime-enabled-features] file.
|
||
* `defaultFontFamily` Object (optional) - Sets the default font for the font-family.
|
||
* `standard` String (optional) - Defaults to `Times New Roman`.
|
||
* `serif` String (optional) - Defaults to `Times New Roman`.
|
||
* `sansSerif` String (optional) - Defaults to `Arial`.
|
||
* `monospace` String (optional) - Defaults to `Courier New`.
|
||
* `cursive` String (optional) - Defaults to `Script`.
|
||
* `fantasy` String (optional) - Defaults to `Impact`.
|
||
* `defaultFontSize` Integer (optional) - Defaults to `16`.
|
||
* `defaultMonospaceFontSize` Integer (optional) - Defaults to `13`.
|
||
* `minimumFontSize` Integer (optional) - Defaults to `0`.
|
||
* `defaultEncoding` String (optional) - Defaults to `ISO-8859-1`.
|
||
* `backgroundThrottling` Boolean (optional) - Whether to throttle animations and timers
|
||
when the page becomes background. This also affects the
|
||
[Page Visibility API](#page-visibility). Defaults to `true`.
|
||
* `offscreen` Boolean (optional) - Whether to enable offscreen rendering for the browser
|
||
window. Defaults to `false`. See the
|
||
[offscreen rendering tutorial](../tutorial/offscreen-rendering.md) for
|
||
more details.
|
||
* `contextIsolation` Boolean (optional) - Whether to run Electron APIs and
|
||
the specified `preload` script in a separate JavaScript context. Defaults
|
||
to `false`. The context that the `preload` script runs in will still
|
||
have full access to the `document` and `window` globals but it will use
|
||
its own set of JavaScript builtins (`Array`, `Object`, `JSON`, etc.)
|
||
and will be isolated from any changes made to the global environment
|
||
by the loaded page. The Electron API will only be available in the
|
||
`preload` script and not the loaded page. This option should be used when
|
||
loading potentially untrusted remote content to ensure the loaded content
|
||
cannot tamper with the `preload` script and any Electron APIs being used.
|
||
This option uses the same technique used by [Chrome Content Scripts][chrome-content-scripts].
|
||
You can access this context in the dev tools by selecting the
|
||
'Electron Isolated Context' entry in the combo box at the top of the
|
||
Console tab. **Note:** This option is currently experimental and may
|
||
change or be removed in future Electron releases.
|
||
* `nativeWindowOpen` Boolean (optional) - Whether to use native
|
||
`window.open()`. Defaults to `false`. **Note:** This option is currently
|
||
experimental.
|
||
* `webviewTag` Boolean (optional) - Whether to enable the [`<webview>` tag](webview-tag.md).
|
||
Defaults to the value of the `nodeIntegration` option. **Note:** The
|
||
`preload` script configured for the `<webview>` will have node integration
|
||
enabled when it is executed so you should ensure remote/untrusted content
|
||
is not able to create a `<webview>` tag with a possibly malicious `preload`
|
||
script. You can use the `will-attach-webview` event on [webContents](web-contents.md)
|
||
to strip away the `preload` script and to validate or alter the
|
||
`<webview>`'s initial settings.
|
||
* `additionalArguments` String[] (optional) - A list of strings that will be appended
|
||
to `process.argv` in the renderer process of this app. Useful for passing small
|
||
bits of data down to renderer process preload scripts.
|
||
* `safeDialogs` Boolean (optional) - Whether to enable browser style
|
||
consecutive dialog protection. Default is `false`.
|
||
* `safeDialogsMessage` String (optional) - The message to display when
|
||
consecutive dialog protection is triggered. If not defined the default
|
||
message would be used, note that currently the default message is in
|
||
English and not localized.
|
||
* `navigateOnDragDrop` Boolean (optional) - Whether dragging and dropping a
|
||
file or link onto the page causes a navigation. Default is `false`.
|
||
|
||
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`.
|
||
|
||
### 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
|
||
* `title` String
|
||
|
||
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:
|
||
|
||
```javascript
|
||
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 // equivalent to `return false` but not recommended
|
||
}
|
||
```
|
||
_**Note**: There is a subtle difference between the behaviors of `window.onbeforeunload = handler` and `window.addEventListener('beforeunload', handler)`. It is recommended to always set the `event.returnValue` explicitly, instead of only returning a value, as the former works more consistently within Electron._

#### `BrowserWindow.addExtension(path)`
|
||
|
||
* `path` String
|
||
|
||
Adds Chrome extension located at `path`, and returns extension's name.
|
||
|
||
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.removeExtension(name)`
|
||
|
||
* `name` String

is emitted.
|
||
|
||
#### `BrowserWindow.getExtensions()`
|
||
|

|
||
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.

|
||
|
||
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:
|
||
|
||
```javascript
|
||
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`
|
||
|
||
A `WebContents` object this window owns. All web page related events and
|
||
operations will be done via it.
|
||
|
||
See the [`webContents` documentation](web-contents.md) for its methods and
|
||
events.
|
||
|
||
#### `win.id`

|
||
|
||
### 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.
|
||
|
||
#### `win.destroy()`
|
||
|
||
Force closing the window, the `unload` and `beforeunload` event won't be emitted
|
||
for the web page, and `close` event will also not be emitted
|
||
for this window, but it guarantees the `closed` event will be emitted.
|
||
|
||
#### `win.close()`
|
||
|
||
Try to close the window. This has the same effect as a user manually clicking
|
||
the close button of the window. The web page may cancel the close though. See
|
||
the [close event](#event-close).
|
||
|
||
#### `win.focus()`
|
||
|
||
Focuses on the window.
|
||
|
||
#### `win.blur()`
|
||
|
||
Removes focus from the window.
|
||
|
||
#### `win.isFocused()`
|
||
|
||
Returns `Boolean` - Whether the window is focused.
|
||
|
||
#### `win.isDestroyed()`
|
||
|
||
Returns `Boolean` - Whether the window is destroyed.
|
||
|
||
#### `win.show()`
|
||
|
||
Shows and gives focus to the window.
|
||
|
||
#### `win.showInactive()`
|
||
|
||
Shows the window but doesn't focus on it.
|
||
|
||
#### `win.hide()`
|
||
|
||
Hides the window.
|
||
|
||
#### `win.isVisible()`
|
||
|
||
Returns `Boolean` - Whether the window is visible to the user.
|
||
|
||
#### `win.isModal()`
|
||
|
||
Returns `Boolean` - Whether current window is a modal window.
|
||
|
||
#### `win.maximize()`
|
||
|
||
Maximizes the window. This will also show (but not focus) the window if it
|
||
isn't being displayed already.
|
||
|
||
#### `win.unmaximize()`
|
||
|
||
Unmaximizes the window.
|
||
|
||
#### `win.isMaximized()`
|
||
|
||
Returns `Boolean` - Whether the window is maximized.
|
||
|
||
#### `win.minimize()`
|
||
|
||
Minimizes the window. On some platforms the minimized window will be shown in
|
||
the Dock.
|
||
|
||
#### `win.restore()`
|
||
|
||
Restores the window from minimized state to its previous state.
|
||
|
||
#### `win.isMinimized()`
|
||
|
||
Returns `Boolean` - Whether the window is minimized.
|
||
|
||
#### `win.setFullScreen(flag)`
|
||
|
||
* `flag` Boolean
|
||
|
||
Sets whether the window should be in fullscreen mode.
|
||
|
||
#### `win.isFullScreen()`
|
||
|
||
Returns `Boolean` - Whether the window is in fullscreen mode.
|
||
|
||
#### `win.setSimpleFullScreen(flag)` _macOS_
|
||
|
||
* `flag` Boolean
|
||
|
||
Enters or leaves simple fullscreen mode.
|
||
|
||
Simple fullscreen mode emulates the native fullscreen behavior found in versions of Mac OS X prior to Lion (10.7).
|
||
|
||
#### `win.isSimpleFullScreen()` _macOS_
|
||
|
||
Returns `Boolean` - Whether the window is in simple (pre-Lion) fullscreen mode.
|
||
|
||
#### `win.isNormal()`
|
||
|
||
Returns `Boolean` - Whether the window is in normal state (not maximized, not minimized, not in fullscreen mode).
|
||
|
||
#### `win.setAspectRatio(aspectRatio[, extraSize])` _macOS_
|
||
|
||
* `aspectRatio` Float - The aspect ratio to maintain for some portion of the
|
||
content view.
|
||
* `extraSize` [Size](structures/size.md) - The extra size not to be included while
|
||
maintaining the aspect ratio.
|
||
|
||
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. Sum any extra width and
|
||
height areas you have within the overall content view.
|
||
|
||
Calling this function with a value of `0` will remove any previously set aspect
|
||
ratios.
|
||
|
||
#### `win.previewFile(path[, displayName])` _macOS_
|
||
|
||
* `path` String - The absolute path to the file to preview with QuickLook. This
|
||
is important as Quick Look uses the file name and file extension on the path
|
||
to determine the content type of the file to open.
|
||
* `displayName` String (optional) - The name of the file to display on the
|
||
Quick Look modal view. This is purely visual and does not affect the content
|
||
type of the file. Defaults to `path`.
|
||
|
||
Uses [Quick Look][quick-look] to preview a file at a given path.
|
||
|
||
#### `win.closeFilePreview()` _macOS_
|
||
|
||
Closes the currently open [Quick Look][quick-look] panel.
|
||
|
||
#### `win.setBounds(bounds[, animate])`
|
||
|
||
* `bounds` [Rectangle](structures/rectangle.md)
|
||
* `animate` Boolean (optional) _macOS_
|
||
|
||
Resizes and moves the window to the supplied bounds
|
||
|
||
#### `win.getBounds()`
|
||
|
||
Returns [`Rectangle`](structures/rectangle.md)
|
||
|
||
#### `win.setContentBounds(bounds[, animate])`
|
||
|
||
* `bounds` [Rectangle](structures/rectangle.md)
|
||
* `animate` Boolean (optional) _macOS_
|
||
|
||
Resizes and moves the window's client area (e.g. the web page) to
|
||
the supplied bounds.
|
||
|
||
#### `win.getContentBounds()`
|
||
|
||
Returns [`Rectangle`](structures/rectangle.md)
|
||
|
||
#### `win.getNormalBounds()`
|
||
|
||
Returns [`Rectangle`](structures/rectangle.md) - Contains the window bounds of the normal state
|
||
|
||
**Note:** whatever the current state of the window : maximized, minimized or in fullscreen, this function always returns the position and size of the window in normal state. In normal state, getBounds and getNormalBounds returns the same [`Rectangle`](structures/rectangle.md).
|
||
|
||
#### `win.setEnabled(enable)`
|
||
|
||
* `enable` Boolean
|
||
|
||

|
||
|
||
#### `win.getContentSize()`
