QGraphicsBlurEffect

The QGraphicsBlurEffect class provides a blur effect.

This class is a JS wrapper around Qt's QGraphicsBlurEffect class

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

const { QGraphicsBlurEffect } = require("@nodegui/nodegui");
const blur = new QGraphicsBlurEffect();
blur.setBlurRadius(8);
