/**

> The QGraphicsDropShadowEffect class provides a drop shadow effect.

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

A drop shadow effect renders the source with a drop shadow.

### Example

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

const shadow = new QGraphicsDropShadowEffect();
shadow.setBlurRadius(8);
```
