@nodegui/nodegui/dist/lib/QtGui/QApplication.d.ts

A cross-platform library to build native desktop apps.

import { NativeElement } from '../core/Component';
import { QClipboard } from './QClipboard';
import { QStyle } from './QStyle';
import { QObjectSignals, QObject } from '../QtCore/QObject';
import { QPalette } from './QPalette';
import { QScreen } from './QScreen';
import { QIcon } from './QIcon';
/**

> QApplication is the root object for the entire application. It manages app level settings.

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

The QApplication class manages the GUI application's control flow and main settings. In NodeGui you will never create an instance of it manually. NodeGui's internal runtime `Qode` does it for you on app start. You can access the initialised QApplication though if needed.

### Example

```js
const { QApplication } = require("@nodegui/nodegui");

const qApp = QApplication.instance();
qApp.quit();
```
