}
//设置全屏
mainWindow.setFullScreen(true);
// and load the index.html of the app.
mainWindow.loadURL(url.format({
    pathname: path.join(__dirname, 'index.html'),
    protocol: 'file:',

// Open the DevTools.
mainWindow.webContents.openDevTools();
// Emitted when the window is closed.
    mainWindow.on('closed', function() {
        // Dereference the window object, usually you would store windows
        // in an array if your app supports multi windows, this is the time
        // when you should delete the corresponding element.
        mainWindow = null;
        app.quit()
    })

}
开启第二块平面
ipc.on(“pingmuorder”, (event, arg) => {

win.loadURL(`file://${__dirname}/pingmuorder.html`);
win.setMenu(null);
win.webContents.on('did-finish-load', () => {
    win.webContents.send('request', arg);
});

});

准备启动项目
app.on(‘ready’, createWindow)

关闭屏幕退出
app.on(‘window-all-closed’, function() {

if(process.platform !== 'darwin') {
    app.quit()
}

})
