Returns: QItemSelectionModel

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

addEventListenerSignalType›(signalType: SignalType, callback: QItemSelectionModelSignals[SignalType], options?: EventListenerOptions): void

Inherited from EventWidget.addEventListener

Type parameters:

SignalType: keyof QItemSelectionModelSignals

Parameters:

NameTypeDescription
signalTypeSignalTypeSignalType is a signal from the widgets signals interface.
callbackQItemSelectionModelSignals[SignalType]Corresponding callback for the signal as mentioned in the widget's signal interface
options?EventListenerOptionsExtra 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

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:

NameTypeDescription
isProcessedbooleantrue if the event has been processed.

Returns: void
