javascript - native 菜单不显示 OS X Electron

Question

我使用 electron-quick-start 创建了一个 Electron 应用程序，我希望唯一显示的 native 菜单是“编辑”菜单，里面有常见的嫌疑人。

但是，在搜索并用尽“Electron 菜单不起作用”的所有相关 Google 结果后，我不知所措。

我当前的 main.js 文件:

const {app, Menu, 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 mainWindow;

app.setName('mathulator');

function createWindow () {
  // Create the browser window.
  mainWindow = new BrowserWindow({width: 900, height: 550})

  // and load the index.html of the app.
  mainWindow.loadURL(`file://${__dirname}/index.html`)

  // 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.

  const template = [
    {
        label: 'Mathulator',
        submenu: [
            {
                role: 'quit'
            }
        ]
    },
    {
      label: 'Edit',
      submenu: [
        {
          role: 'undo'
        },
        {
          role: 'redo'
        },
        {
          type: 'separator'
        },
        {
          role: 'cut'
        },
        {
          role: 'copy'
        },
        {
          role: 'paste'
        },
        {
          role: 'pasteandmatchstyle'
        },
        {
          role: 'delete'
        },
        {
          role: 'selectall'
        }
      ]
    }
   ]

  mainWindow.setMenu(Menu.buildFromTemplate(template))

  // 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
  })
}

// 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', function () {
  // On OS X 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', function () {
  // On OS X 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 (mainWindow === null) {
    createWindow()
  }
})

我也用electron-packager打包过，没用。

我在 main.js 文件中运行它，我可以从网络上大量模糊或复杂的信息中收集到它，这是主要过程，因此我应该在其中创建菜单。

我还尝试在 render.js 中执行此操作，我看到了建议。无济于事。它会显示默认的 Electron 快速启动菜单，或者只是一个以应用程序命名的简单菜单，其中包含一个标记为“退出”的项目。

我可能做错了什么，我可能从现有信息中误解了什么？

编辑: 我实际上附加了错误的文件，第一次尝试使用 Menu.setApplicationMenu()，如下所示:

const {app, Menu, 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 mainWindow;

app.setName('mathulator');

function createWindow () {
    // Create the browser window.
    mainWindow = new BrowserWindow({width: 900, height: 550});

    // and load the index.html of the app.
    mainWindow.loadURL(`file://${__dirname}/index.html`);

    // 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;
    });
}

// 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', function () {
    // On OS X 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', function () {
    // On OS X 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 (mainWindow === null) {
        createWindow();
    }
})

const template = [
    {
        label: 'Mathulator',
        submenu: [
            {
                role: 'quit'
            }
        ]
    },
    {
        label: 'Edit',
        submenu: [
            {
                role: 'undo'
            },
            {
                role: 'redo'
            },
            {
                type: 'separator'
            },
            {
                role: 'cut'
            },
            {
                role: 'copy'
            },
            {
                role: 'paste'
            },
            {
                role: 'pasteandmatchstyle'
            },
            {
                role: 'delete'
            },
            {
                role: 'selectall'
            }
        ]
    }
];

Menu.setApplicationMenu(Menu.buildFromTemplate(template));

这里的问题是 BrowserWindow.setMenu() 仅在 Windows 和 Linux 上可用。在 macOS 上你应该使用 Menu.setApplicationMenu() .
