/**

> Lines up child widgets horizontally or vertically.

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

### Example

```javascript
// This example arranges two calendars horizontally.

const { QBoxLayout, QCalendarWidget } from "@vixen-js/core";

const centralWidget = new QWidget();
const boxLayout = new QBoxLayout(0);

boxLayout.addWidget(new QCalendarWidget());
boxLayout.addWidget(new QCalendarWidget());
centralWidget.setLayout(boxLayout);
```
