> 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.
