如何从electron应用程序中删除菜单栏

我知道有人问过这个问题，但之前的答案不起作用。这是我的第一个电子应用程序

这是我的main.js

const { app, BrowserWindow } = require('electron')

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let win

function createWindow () {
    // Create the browser window.
    win = new BrowserWindow({
        width: 800,
        height: 600,
        webPreferences: {
            nodeIntegration: true
        }
    })

    // and load the index.html of the app.
    win.loadFile('index.html')

    // Open the DevTools.
    //win.webContents.openDevTools()

    // Emitted when the window is closed.
    win.on('closed', () => {
        // 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.
        win = null
    })

}

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', createWindow)

// Quit when all windows are closed.
app.on('window-all-closed', () => {
    // On macOS it is common for applications and their menu bar
    // to stay active until the user quits explicitly with Cmd + Q
    if (process.platform !== 'darwin') {
        app.quit()
    }
})

app.on('activate', () => {
    // On macOS it's common to re-create a window in the app when the
    // dock icon is clicked and there are no other windows open.
    if (win === null) {
        createWindow()
    }
    win.setMenu(null);
})


// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.

我认为

win.setMenu（null）

将删除菜单栏，但不会删除。我需要做什么才能完全删除此项

--我发现唯一接近的想法是让应用程序无框架

  win = new BrowserWindow({
            width: 800,
            height: 600,
            frame: false,
            webPreferences: {
                nodeIntegration: true
            }
        })

对于Windows和Linux：

require('electron').Menu.setApplicationMenu(null);

请参阅@DanD的可能副本。这些答案似乎都不适用于electron 7What OS？您的代码似乎只适合在MacOS中重新启动应用程序。在（'activate'，…）块上，尝试将此行置于app.on之外。此外，没有办法隐藏MacOS的上部菜单。当您将其放在激活事件之外时，代码会起作用
