QGraphicsDropShadowEffect

The QGraphicsDropShadowEffect class provides a drop shadow effect.

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

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

Example

const { QGraphicsDropShadowEffect } = require("@nodegui/nodegui");

const shadow = new QGraphicsDropShadowEffect();

shadow.setBlurRadius(8);

Methods

addEventListener

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

Inherited from EventWidget.addEventListener

Type parameters:

▪ SignalType: keyof QGraphicsDropShadowEffectSignals

Parameters:

Name	Type	Description
signalType	SignalType	SignalType is a signal from the widgets signals interface.
callback	QGraphicsDropShadowEffectSignals[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:
