Methods

addEventListener

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

Inherited from EventWidget.addEventListener

Type parameters:

▪ SignalType: keyof any

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

Inherited from NodeObject.setObjectName

Parameters:

Name	Type
objectName	string

Returns: void

---

setProperty

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

Inherited from NodeObject.setProperty

Parameters:

Name	Type
name	string
value	QVariantType

Returns: boolean
