Electron自定义菜单

直接粘main.js的代码吧，其中正常部分去掉了中文注释，有中文部分就是菜单相关部分，基本就是最下面的一堆。

const electron = require('electron')
const app = electron.app
const BrowserWindow = electron.BrowserWindow
const Menu = electron.Menu
const path = require('path')
if (process.mas) app.setName('Your Electron App Name')

let mainWindow

function createWindow () {
  let windowOptions = {
    width: 1220,
    height: 780,
    minWidth: 1220,
    minHeight: 780,
    title: app.getName()
  }

  if (process.platform === 'linux') {
    windowOptions.icon = path.join(__dirname, '/app/ico/your-ico.png')
  }

  mainWindow = new BrowserWindow(windowOptions);
  mainWindow.loadURL(path.join('file://', __dirname, '/index.html'))

  mainWindow.on('closed', function () {
    mainWindow = null
  })
}

app.on('ready', function() {
  const menu = Menu.buildFromTemplate(template)
  Menu.setApplicationMenu(menu) // 设置菜单部分
  createWindow()
})

app.on('window-all-closed', function () {
  if (process.platform !== 'darwin') app.quit()
})

app.on('activate', function () {
  if (mainWindow === null) createWindow()
})

app.on('browser-window-created', function () {
    let reopenMenuItem = findReopenMenuItem()
    if (reopenMenuItem) reopenMenuItem.enabled = false
})

app.on('window-all-closed', function () {
    let reopenMenuItem = findReopenMenuItem()
    if (reopenMenuItem) reopenMenuItem.enabled = true
    app.quit()
})
