/**

> Create and control font dialogs.

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

The `QFontDialog` class provides a dialog widget for selecting a font.

### Example

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

const fontDialog = new QFontDialog();
fontDialog.exec();
const font = fontDialog.currentFont();
console.log(font);

```
