## Class: BrowserView
|
|
|
|
> Create and control views.
|
|
|
|
Process: [Main](../glossary.md#main-process)
|
|
|
|
A `BrowserView` can be used to embed additional web content into a
|
|
[`BrowserWindow`](browser-window.md). It is like a child window, except that it is positioned
|
|
relative to its owning window. It is meant to be an alternative to the
|
|
`webview` tag.
|
|
|
|
### Example
|
|
|
|
```javascript
|
|
// In the main process.
|
|
const { BrowserView, BrowserWindow } = require('electron')
|
|
|
|
const win = new BrowserWindow({ width: 800, height: 600 })
|
|
|
|
const view = new BrowserView()
|
|
win.setBrowserView(view)
|
|
view.setBounds({ x: 0, y: 0, width: 300, height: 300 })
|
|
view.webContents.loadURL('https://electronjs.org')
|
|
```
|
|
|
|
### `new BrowserView([options])` _Experimental_

|
|
|
|
#### `view.destroy()`
|
|

|
Force closing the view, the `unload` and `beforeunload` events won't be emitted

|
|
with the window. `false` by default.
|
|

|
|
together with the window. `false` by default.
|
|

|
|
and shrink proportionally with the window. `false` by default.
|
|
* `vertical` Boolean (optional) - If `true`, the view's y position and height will grow
|
|
and shrink proportionally with the window. `false` by default.
|
|
|

#### `view.setBounds(bounds)` _Experimental_
|
|
|
|
* `bounds` [Rectangle](structures/rectangle.md)

Resizes and moves the view to the supplied bounds relative to the window.
|
|
