Class: QMainWindow

Create and control windows.

This class is a JS wrapper around Qt's QMainWindow class

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.

QMainWindow inherits from NodeWidget

Example

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.
