QGridLayout

The QGridLayout class lays out widgets in a grid.

This class is a JS wrapper around Qt's QGridLayout

Example

const { QGridLayout, QWidget, QLabel } = require("@nodegui/nodegui");

const view = new QWidget();

const layout = new QGridLayout();

view.setLayout(layout);

const label = new QLabel();

label.setText("label1");

const label2 = new QLabel();

label2.setText("label2");

layout.addWidget(label);

layout.addWidget(label2);

---

addEventListener

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

Inherited from EventWidget.addEventListener

Type parameters:

▪ SignalType: keyof QGridLayoutSignals

Parameters:

Name	Type	Description
signalType	SignalType	SignalType is a signal from the widgets signals 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
