A cross-platform library to build native desktop apps.

import { NativeElement } from '../core/Component';
/**

> Create and control windows.

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

A `QMainWindow` provides a main application window. Every widget in NodeGui should be a child/nested child of QMainWindow. QMainWindow in NodeGui is also responsible for FlexLayout calculations of its children.

### Example

```javascript
const { QMainWindow, QWidget } = require("@nodegui/nodegui");

const win = new QMainWindow();

const centralWidget = new QWidget();
win.setCentralWidget(centralWidget);

win.show();

global.win = win; // prevent's gc of win
```

QMainWindow needs to have a central widget set before other widgets can be added as a children/nested children.
Once a central widget is set you can add children/layout to the central widget.
