/**

> Create and control text browser.

* **This class is a JS wrapper around Qt's [QTextBrowser class](https://doc.qt.io/qt-5/qtextbrowser.html)**

A `QTextBrowser` provides ability to add and manipulate native text browser widgets.

### Example

```javascript
import { QTextBrowser } from "@vixen-js/core";

const textBrowser = new QTextBrowser();
```
