## 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')
|
|
|
|
let win = new BrowserWindow({ width: 800, height: 600 })
|
|
win.on('closed', () => {
|
|
win = null
|
|
})
|
|
|
|
let view = new BrowserView()
|
|
win.setBrowserView(view)
|
|
view.setBounds({ x: 0, y: 0, width: 300, height: 300 })
|
|
view.webContents.loadURL('https://electronjs.org')
|
|
```
