# BrowserWindow
|
||
|
||
The `BrowserWindow` class gives you the ability to create a browser window. For
|
||
example:
|
||
|
||
```javascript
|
||
// In the main process.
|
||
const BrowserWindow = require('electron').BrowserWindow;
|
||
|
||
// Or in the renderer process.
|
||
const BrowserWindow = require('electron').remote.BrowserWindow;
|
||
|
||
var win = new BrowserWindow({ width: 800, height: 600, show: false });
|
||
win.on('closed', function() {
|
||
win = null;
|
||
});
|
||
|
||
win.loadURL('https://github.com');
|
||
win.show();
|
||
```
|
||
|
||
You can also create a window without chrome by using
|
||
[Frameless Window](frameless-window.md) API.
|
||
|
||
## Class: BrowserWindow
|
||
|
||
`BrowserWindow` is an
|
||
[EventEmitter](http://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])`

|
||
|
||
The possible values and behaviors of `type` option are platform dependent,
|
||
supported values are:
|
||
|
||
* On Linux, possible types are `desktop`, `dock`, `toolbar`, `splash`,
|
||
`notification`.
|
||
* On OS X, 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.
|
||
|
||
The `titleBarStyle` option is only supported on OS X 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 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](process.md#event-loaded).
|
||
* `session` [Session](session.md#class-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` would 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 setting `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 a 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`.
|
||
* `plugins` Boolean - Whether plugins should be enabled. Default is `false`.

||
* `experimentalFeatures` Boolean - Enables Chromium's experimental features.
|
||
Default is `false`.

||
* `experimentalCanvasFeatures` Boolean - Enables Chromium's experimental
|
||
canvas features. Default is `false`.
|
||
* `directWrite` Boolean - Enables DirectWrite font rendering system on
|
||
Windows. Default is `true`.
|
||
* `blinkFeatures` String - A list of feature strings separated by `,`, like
|
||
`CSSVariables,KeyboardEventKey`. The full list of supported feature strings
|
||
can be found in the [setFeatureEnabledFromString][blink-feature-string]
|
||
function.

|
||
|
||
## Events
|
||
|
||
The `BrowserWindow` object emits 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()`
|
||
would prevent the native window's title to change.
|
||
|
||
### 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 an empty string or `false` would cancel the
|
||
close. For example:
|
||
|
||
```javascript
|
||
window.onbeforeunload = function(e) {
|
||
console.log('I do not want to be closed');
|
||
|
||
// Unlike usual browsers, in which a string should be returned and the user is
|
||
// prompted to confirm the page unload, Electron gives developers more options.
|
||
// Returning empty string or false would prevent the unloading now.
|
||
// You can also 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 anymore.
|
||
|
||
### 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: 'maximize'
|
||
|
||
Emitted when window is maximized.
|
||
|
||
### Event: 'unmaximize'
|
||
|
||
Emitted when the window exits from maximized state.
|
||
|
||
### Event: 'minimize'
|
||
|
||
Emitted when the window is minimized.
|
||
|
||
### Event: 'restore'
|
||
|
||
Emitted when the window is restored from minimized state.
|
||
|
||
### Event: 'resize'
|
||
|
||
Emitted when the window is getting resized.
|
||
|
||
### Event: 'move'
|
||
|
||
Emitted when the window is getting moved to a new position.
|
||
|
||
__Note__: On OS X this event is just an alias of `moved`.
|
||
|
||
### Event: 'moved' _OS X_
|
||
|
||
Emitted once when the window is moved to a new position.
|
||
|
||
### Event: 'enter-full-screen'
|
||
|
||
Emitted when the window enters full screen state.
|
||
|
||
### Event: 'leave-full-screen'
|
||
|
||
Emitted when the window leaves full screen state.
|
||
|
||
### Event: 'enter-html-full-screen'
|
||
|
||
Emitted when the window enters full screen state triggered by html api.
|
||
|
||
### Event: 'leave-html-full-screen'
|
||
|
||
Emitted when the window leaves full screen state triggered by html api.
|

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.
|
||
|
||
```js
|
||
someWindow.on('app-command', function(e, cmd) {
|
||
// Navigate the window back when the user hits their mouse back button
|
||
if (cmd === 'browser-backward' && someWindow.webContents.canGoBack()) {

|
||
```
|
||
|
||
### `win.webContents`
|

|
||
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 with 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()`
|
||
|
||
Focus on the window.
|
||
|
||
### `win.isFocused()`
|
||
|
||
Returns a boolean, whether the window is focused.
|
||
|
||
### `win.show()`
|
||
|
||
Shows and gives focus to the window.
|
||
|
||

|
||
Shows the window but doesn't focus on it.
|
||
|
||
### `win.hide()`
|
||
|
||

|
||
|
||
### `win.isVisible()`
|
||
|
||
Returns a boolean, whether the window is visible to the user.
|
||
|
||
### `win.maximize()`
|
||
|
||
Maximizes the window.
|
||
|
||
### `win.unmaximize()`
|
||
|
||
Unmaximizes the window.
|
||
|
||
### `win.isMaximized()`
|
||
|
||
Returns a 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 a boolean, whether the window is minimized.
|
||
|
||
### `win.setFullScreen(flag)`
|
||
|
||
* `flag` Boolean
|
||
|
||
Sets whether the window should be in fullscreen mode.
|
||
|
||
### `win.isFullScreen()`
|
||
|
||
Returns a boolean, whether the window is in fullscreen mode.
|
||
|
||
### `win.setAspectRatio(aspectRatio[, extraSize])` _OS X_
|
||
|
||
* `aspectRatio` The aspect ratio we want to maintain for some portion of the
|
||
content view.
|
||
* `extraSize` Object (optional) - The extra size not to be included while
|
||
maintaining the aspect ratio. Properties:
|
||
* `width` Integer
|
||
* `height` Integer
|
||
|
||
This will have 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.
|
||
|
||
### `win.setBounds(options[, animate])`
|
||
|
||
* `options` Object, properties:
|
||
|
||
* `x` Integer
|
||
* `y` Integer

|
||
* `height` Integer
|
||
|
||

|
||
* `height` Integer
