Returns: QObject
Properties

• native: NativeElement | null
Inherited from Component.native
Methods
_id
â–¸ _id(): number
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
: Signals[SignalType], options?
: EventListenerOptions): void
Inherited from EventWidget.addEventListener
Type parameters:
â–ª SignalType: keyof Signals
Parameters:
Name | Type | Description |
---|---|---|
signalType | SignalType | SignalType is a signal from the widgets signals interface. |
callback | Signals[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:
â–¸ addEventListener(eventType

â–ªOptional
options: EventListenerOptions
Extra optional options controlling how this event listener is added.
For example in the case of QPushButton:
Returns: void
children
â–¸ children(): QObject[]

delete
â–¸ delete(): void
Returns: void
deleteLater
â–¸ deleteLater(): void
Returns: void
dumpObjectInfo
â–¸ dumpObjectInfo(): void
Returns: void

Returns: void
eventProcessed
â–¸ eventProcessed(): boolean
Inherited from EventWidget.eventProcessed
Get the state of the event processed flag
See setEventProcessed()
.

: Signals[SignalType], options?
: EventListenerOptions): void
Inherited from EventWidget.removeEventListener
Type parameters:
â–ª SignalType: keyof Signals
Parameters:

â–¸ removeEventListener(eventType
: WidgetEventTypes, callback
: function, options?
: EventListenerOptions): void
Inherited from EventWidget.removeEventListener
Parameters:

â–ª callback: function
â–¸ (event?
: NativeRawPointer‹"QEvent"›): void
Parameters:
Name | Type |
---|---|
event? | NativeRawPointer‹"QEvent"› |
â–ªOptional
options: EventListenerOptions
Returns: void
setEventProcessed
â–¸ 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
â–¸ setObjectName(objectName
: string): void
Parameters:
Name | Type |
---|---|
objectName | string |
Returns: void
setParent
â–¸ setParent(parent
: QObject): void
Parameters:
Name | Type |
---|---|
parent | QObject |
Returns: void
setProperty
â–¸ setProperty(name
: string, value
: QVariantType): boolean
Parameters:
Name | Type |
---|---|
name | string |
value | QVariantType |
Returns: boolean
startTimer
â–¸ startTimer(intervalMS
: number, timerType
: TimerType): number
Parameters:
Name | Type | Default |
---|---|---|
intervalMS | number | - |
timerType | TimerType | TimerType.CoarseTimer |
Returns: number
