我正在构建一个带有操作系统托盘菜单的电子应用程序。
在主要过程中,我想听取“关于”菜单项的点击,然后通知渲染器进程,以便它可以相应地更新窗口的视图。
这是我渲染窗口和托盘菜单时主要过程的部分:
const {app, BrowserWindow, Menu, Tray} = require('electron')
const appConfig = require('./appConfig')
const ipc = require('electron').ipcMain
const path = require('path')
const config = require('../config')
let win, tray
function createWindow(){
win = new BrowserWindow({
height: appConfig.window.height,
width: appConfig.window.width
})
win.loadURL(`file://${__dirname}/client/index.html`)
if(appConfig.debugMode){
win.webContents.openDevTools()
}
win.on('closed', () => {
win = null
})
}
function setTrayIcon(){
tray = new Tray(path.resolve(__dirname, './assets/rocketTemplate.png'))
tray.setToolTip('Launch applications by group')
let menuitems = config.groups.map(group => {
return {label: `Launch group: ${group.name}`}
})
win.webContents.send('ShowAboutPage' , {msg:'hello from main process'});
win.webContents.send('ShowAboutPage')
menuitems.unshift({type: 'separator'})
// Here where I add the "About" menu item that has the click event listener
menuitems.unshift({
label: 'About AppLauncher',
click(menuitem, browserWin, event){
// sending a log to the console to confirm that the click listener did indeed hear the click
console.log('about menu clicked')
win.webContents.send('ShowAboutPage')
}
})
menuitems.push({type: 'separator'})
menuitems.push({label: 'Quit AppLauncher'})
const contextMenu = Menu.buildFromTemplate(menuitems)
tray.setContextMenu(contextMenu)
}
app.on('ready', () => {
createWindow()
setTrayIcon()
})
这是应该监听频道消息的渲染器脚本:
const Vue = require('vue')
const App = require('./App.vue')
const ipc = require('electron').ipcRenderer
ipc.on('ShowAboutPage', () => {
console.log('show about fired in store')
alert('show about fired in store')
this.notificationMessage = 'Show about page'
})
require('./style/base.sass')
new Vue({
el: '#app',
render: h => h(App)
})
当我单击托盘中的“关于”菜单时,我从主进程获得console.log输出,但我从未在渲染器进程中收到console.log或alert。
我的应用程序只有一个窗口(由窗口关闭时win
变量的无效证明)所以它似乎不是我将消息发送到错误的渲染器进程的问题。
我浏览了electron documentation on using webContents to send messages to renderer instances,看起来我的代码结构正确,但显然我遗漏了一些东西。
有什么想法吗?

尝试将您的渲染器脚本重写为
const { ipcRenderer } = require("electron");
ipcRenderer.on("ShowAboutPage", () => {
//etc
});
