Preparation for Electron

quasar dev -m electron# passing extra parameters and/or options to
# underlying "electron" executable:
quasar dev -m electron -- --no-sandbox --disable-setuid-sandbox
# when on Windows and using Powershell:
quasar dev -m electron '--' --no-sandbox --disable-setuid-sandbox

基本命令

quasar dev -m electron

指定以 Electron 模式运行启动 Quasar 开发服务器

传递参数

Linux/MacOS 语法:

quasar dev -m electron -- --no-sandbox --disable-setuid-sandbox

• --: 这个符号表示后面的参数是传递给底层 Electron 可执行文件的，而不是 Quasar CLI

Windows PowerShell 语法:

quasar dev -m electron '--' --no-sandbox --disable-setuid-sandbox

• 在 PowerShell 中需要用引号包裹 --

参数解释

–no-sandbox

禁用 Chromium 的沙盒(sandbox)安全机制沙盒是一种安全功能，限制应用程序对系统资源的访问禁用沙盒可能会降低安全性，但在某些环境下是必要的

–disable-setuid-sandbox

禁用 setuid 沙盒setuid 是一种 Unix 权限机制，允许程序以更高权限运行，在某些 Linux 系统上，如果无法使用 setuid 沙盒，需要禁用此功能

Frameless Electron Window

安装依赖

npm install --save @electron/remote

修改electron-main.js

import { app, BrowserWindow, nativeTheme } from 'electron'
import { initialize, enable } from '@electron/remote/main' // <-- add this
import path from 'path'initialize() // <-- add this// ...mainWindow = new BrowserWindow({width: 1000,height: 600,useContentSize: true,frame: false // <-- add thiswebPreferences: {sandbox: false // <-- to be able to import @electron/remote in preload script// ...}
})enable(mainWindow.webContents) // <-- add thismainWindow.loadURL(process.env.APP_URL)// ...

[!warning]
官方文档中import { initialize, enable } from ‘@electron/remote/main’
这里我出现了报错
改为import { initialize, enable } from '@electron/remote/main/index.js’正常运行

[!success] 成功
接下里我们需要处理窗口拖拽以及最小化、最大化与关闭应用

预加载脚本

由于我们无法直接从渲染线程访问 Electron，需要通过 electron 预加载脚本( src-electron/main-process/electron-preload.js )提供必要功能。因此我们将其修改为：

//src-electron/main-process/electron-preload
import { contextBridge } from 'electron'
import { BrowserWindow } from '@electron/remote'contextBridge.exposeInMainWorld('myWindowAPI', {minimize () {BrowserWindow.getFocusedWindow().minimize()},toggleMaximize () {const win = BrowserWindow.getFocusedWindow()if (win.isMaximized()) {win.unmaximize()} else {win.maximize()}},close () {BrowserWindow.getFocusedWindow().close()}
})

处理窗口拖拽

当我们使用无边框窗口（仅限无边框！）时，还需要为用户提供在屏幕上移动应用窗口的方式。为此，您可以使用 q-electron-drag 和 q-electron-drag--exception Quasar CSS 辅助类。

[!TIPS] 提示
也许你可以在layout文件中为某些组件添加类q-electron-drag试试

该功能允许用户在屏幕上点击、按住并同时拖动鼠标时，拖拽应用程序窗口。

最小化、最大化与关闭应用

在某些vue文件（例如添加在MainLayout.vue中）
Template

<q-space /><q-btn dense flat icon="minimize" @click="minimize" />
<q-btn dense flat icon="crop_square" @click="toggleMaximize" />
<q-btn dense flat icon="close" @click="closeApp" />

[!TIP]
若觉得iconminimize不太习惯（位于底部），可以使用remove（竖直居中）
q-space的作用是将q-btn挤到右边

选项式

<script>
// We guard the Electron API calls with the optional chaining JS operator,
// but this is only needed if we build same app with other Quasar Modes
// as well (SPA/PWA/Cordova/SSR...)export default {setup () {function minimize () {window.myWindowAPI?.minimize()}function toggleMaximize () {window.myWindowAPI?.toggleMaximize()}function closeApp () {window.myWindowAPI?.close()}return { minimize, toggleMaximize, closeApp }}
}
</script>

组合式

<script setup>
// We guard the Electron API calls with the optional chaining JS operator,
// but this is only needed if we build same app with other Quasar Modes
// as well (SPA/PWA/Cordova/SSR...)function minimize() {if (process.env.MODE === 'electron') {window.myWindowAPI?.minimize()}
}function toggleMaximize() {if (process.env.MODE === 'electron') {window.myWindowAPI?.toggleMaximize()}
}function closeApp() {if (process.env.MODE === 'electron') {window.myWindowAPI?.close()}
}
</script>

Build

quasar build -m electron -d
