Methods

addEventListener

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

Inherited from EventWidget.addEventListener

Type parameters:

▪ SignalType: keyof QScreenSignals

Parameters:

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

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

Parameters:
