> 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);
```

export declare class QGraphicsBlurEffect extends QGraphicsEffect<QGraphicsBlurEffectSignals> {
    constructor(arg?: QObject | NativeElement);
    setBlurHints(hints: BlurHint): void;
    blurHints(): BlurHint;
    setBlurRadius(blurRadius: number): void;
    blurRadius(): number;
}
export declare enum BlurHint {
    PerformanceHint = 0,
    QualityHint = 1,
    AnimationHint = 2
}
export interface QGraphicsBlurEffectSignals extends QGraphicsEffectSignals {
    onBlurHintsChange: (hints: BlurHint) => void;
    onBlurRadiusChange: (radius: number) => void;
