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);

Overrides QObject.constructor

Parameters:

Returns: QGraphicsDropShadowEffect

Properties

• native: NativeElement | null

Inherited from Component.native

Methods

_id

▸ _id(): number

Inherited from QObject._id

Get an ID identifying the underlying C++ object.

This can be useful when debugging memory problems with help from setLogCreateQObject() and setLogDestroyQObject(). The number is hash of the memory address of the C++ object.

Returns: number

a unique number which is valid for the lifetime of the C++ object.

addEventListener

▸ addEventListener‹SignalType›(signalType: SignalType, callback: QGraphicsDropShadowEffectSignals[SignalType], options?: EventListenerOptions): 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
`options?`	EventListenerOptions	Extra optional options controlling how this event listener is added.

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, options?: EventListenerOptions): void

Inherited from EventWidget.addEventListener

Parameters:

▪ eventType: WidgetEventTypes

▪ callback: function

▸ (event?: NativeRawPointer‹"QEvent"›): void

Parameters:

Name	Type
`event?`	NativeRawPointer‹"QEvent"›

▪Optional options: EventListenerOptions

Extra optional options controlling how this event listener is added.

For example in the case of QPushButton:

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

Returns: void

blurRadius

▸ blurRadius(): number

Returns: number

children

▸ children(): QObject[]

Inherited from QObject.children

Returns: QObject[]

Inherited from EventWidget.eventProcessed

Get the state of the event processed flag

See setEventProcessed().

Returns: boolean

boolean True if the current event is flagged as processed.

inherits

Inherited from QObject.inherits

Parameters:

Name	Type
`className`	string

Returns: boolean

isEnabled

▸ isEnabled(): boolean

Inherited from QGraphicsEffect.isEnabled

Returns: void

objectName

▸ objectName(): string

Inherited from QObject.objectName

Returns: string

parent

▸ parent(): QObject

Inherited from QObject.parent

Returns: QObject

property

▸ property(name: string): QVariant

Inherited from QObject.property

Parameters:

Name	Type
`name`	string

Returns: QVariant

removeEventListener

▸ removeEventListener‹SignalType›(signalType: SignalType, callback: QGraphicsDropShadowEffectSignals[SignalType], options?: EventListenerOptions): void

Inherited from EventWidget.removeEventListener

Type parameters:

▪ SignalType: keyof QGraphicsDropShadowEffectSignals

Parameters:

Name	Type
`signalType`	SignalType
`callback`	QGraphicsDropShadowEffectSignals[SignalType]
`options?`	EventListenerOptions

Returns: void

▸ removeEventListener(eventType: WidgetEventTypes, callback: function, options?: EventListenerOptions): void

Inherited from EventWidget.removeEventListener

Parameters:

▪ eventType: WidgetEventTypes

▪ callback: function

▸ (event?: NativeRawPointer‹"QEvent"›): void

Parameters:

Name	Type
`event?`	NativeRawPointer‹"QEvent"›

▪Optional options: EventListenerOptions

Returns: void

setBlurRadius

▸ setBlurRadius(blurRadius: number): void

Parameters:

Name	Type
`blurRadius`	number

Returns: void

setColor

▸ setColor(color: QColor): void

Parameters:

Name	Type
`color`	QColor

Returns: void

setEnabled

▸ setEnabled(enable: boolean): void

Inherited from QGraphicsEffect.setEnabled

Parameters:

Name	Type
`enable`	boolean

Returns: void

setEventProcessed

▸ setEventProcessed(isProcessed: boolean): void

Inherited from EventWidget.setEventProcessed

Mark the current event as having been processed

This method is used to indicate that the currently dispatched event has been processed and no further processing by superclasses is required. It only makes sense to call this method from an event handler.

When set, this flag will cause NodeGui's QObject::event() method to return true and not call the superclass event(), effectively preventing any further processing on this event.

Parameters:

Name	Type	Description
`isProcessed`	boolean	true if the event has been processed.

Returns: void

setObjectName

▸ setObjectName(objectName: string): void

Inherited from QObject.setObjectName

Parameters:

Name	Type
`objectName`	string

Returns: void

setParent

▸ setParent(parent: QObject): void

Inherited from QObject.setParent

Parameters:

Name	Type
`parent`	QObject

Returns: void

setProperty

▸ setProperty(name: string, value: QVariantType): boolean

Inherited from QObject.setProperty

Parameters:

Name	Type
`name`	string
`value`	QVariantType

Returns: boolean

setXOffset

▸ setXOffset(dx: number): void

Parameters:

Name	Type
`dx`	number

Returns: void

setYOffset

▸ setYOffset(dy: number): void

Parameters:

Name	Type
`dy`	number

Returns: void

startTimer

▸ startTimer(intervalMS: number, timerType: TimerType): number

Inherited from QObject.startTimer

Parameters:

Name	Type	Default
`intervalMS`	number	-
`timerType`	TimerType	TimerType.CoarseTimer

Returns: number

xOffset

▸ xOffset(): number

Returns: number

yOffset

▸ yOffset(): number

Returns: number
