qapplication	QApplication	QApplication

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

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

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

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