/**

> The QGraphicsBlurEffect class provides a blur effect.

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

A blur effect blurs the source. This effect is useful for reducing details, such as when the source loses focus and you want to draw attention to other elements.

### Example

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

const blur = new QGraphicsBlurEffect();
blur.setBlurRadius(8);
```
