/**

> Create and control checkbox.

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

A `QCheckBox` provides ability to add and manipulate native checkbox widgets.

### Example

```javascript
const { QCheckBox } = require("@nodegui/nodegui");

const checkbox = new QCheckBox();
checkbox.setText("Hello");
```

    constructor(arg?: QWidget<QWidgetSignals> | NativeElement) {

            native = arg as NativeElement;
        } else if (arg != null) {
            const parent = arg as QWidget;
            native = new addon.QCheckBox(parent.native);
