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);

Methods

addEventListener

▸ addEventListener‹SignalType›(signalType: SignalType, callback: QGraphicsBlurEffectSignals[SignalType]): void

Inherited from EventWidget.addEventListener

Type parameters:

▪ SignalType: keyof QGraphicsBlurEffectSignals

Parameters:

Name	Type	Description
signalType	SignalType	SignalType is a signal from the widgets signals interface.
callback	QGraphicsBlurEffectSignals[SignalType]	Corresponding callback for the signal as mentioned in the widget's signal interface

Returns: void

void

For example in the case of QPushButton:

const button = new QPushButton();

button.addEventListener('clicked',(checked)=>console.log("clicked"));

// here clicked is a value from QPushButtonSignals interface

▸ addEventListener(eventType: WidgetEventTypes, callback: function): void

Inherited from EventWidget.addEventListener

Parameters:

For example in the case of QPushButton:

const button = new QPushButton();

button.addEventListener(WidgetEventTypes.HoverEnter,()=>console.log("hovered"));
