/**

> The QGridLayout class lays out widgets in a grid.

* **This class is a JS wrapper around Qt's [QGridLayout](https://doc.qt.io/qt-5/qgridlayout.html)**

### Example

```javascript
import { QGridLayout, QWidget, QLabel } from "@vixen-js/core";

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);
```
