go桌面，logo桌面

大家好!go桌面今天让小编来大家介绍下关于logo桌面,以下是小编对此问题的归纳整理,让我们一起来看看吧。

go的定位主要是写后端，但是有时候写go的人也想写一些桌面应用，实现一些配置工具啥的，下面介绍lorca库，可以基于webkit和html来实现ui应用。

示例中的代码，主要实现了生成小朋友加减乘除的题目，ui.Bind相当于实现了go函数到浏览器的函数注入功能，这个实现了，剩下的就是写些简单的html显示。代码从vscode拷入，排版没了，可以复制到vscode中看。

package main

import ( "fmt" "log" "net/url"
"./docgen"
"github.com/atotto/clipboard" "github.com/zserge/lorca")
