/**

> Used to edit and display plain text.

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

A `QPlainTextEdit` provides ability to add and manipulate native editable text field widgets.

### Example

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

const plainTextEdit = new QPlainTextEdit();
```
