/**

> Create and control file dialogs.

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

A `QFileDialog` class provides a dialog that allow users to select files or directories.

### Example

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

const fileDialog = new QFileDialog();
fileDialog.setFileMode(FileMode.AnyFile);
fileDialog.setNameFilter('Images (*.png *.xpm *.jpg)');
fileDialog.exec();

const selectedFiles = fileDialog.selectedFiles();
console.log(selectedFiles);

```
