/**

> Create and control a selectable monthly calendar.

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

A `QCalendarWidget` provides a monthly based calendar widget allowing the user to select a date.

### Example

```javascript
import { QCalendarWidget } from "@vixen-js/core";

const calendarWidget = new QCalendarWidget();
// more will follow when .selectedDate() et cetera are implemented
```
