go语言缺乏官方GUI的支持，这点有时候很不方便。
虽然网上有很多开源的实现，但都不太满意，不太好用。
网上开源的有哪些？参见《2019，Go GUI项目爆发的一年？》https://studygolang.com/articles/21525?fr=sidebar
近来出现了很多跨平台的Go GUI项目。
虽说用井喷之势形容有些过了，但是的确有加速的迹象。难道Go语言将要开辟出另一大块疆土？
忙中偷闲，整理了一份目前GUI/图形/图像相关的Go项目列表。见下。欢迎补充。
原生GUI绑定
dlgs是一个跨平台的显示对话框和输入框的Go代码库。
glfw是一个GLFW3绑定库。
go-mobile支持移动平台应用开发（Android和iOS）。（其中包含OpenGL ES 2.0和ES 3.0绑定库。）
go-sdl2是一个SDL2绑定库。
go-gtk是一个GTK2绑定库。
gotk3是一个GTK+3绑定库。
GXUI，Google员工出品，但已经停止维护很久了。
。。。。。。
突然想起来曾经很火的嵌入式GUI，UCGUI多么的小巧灵活，且是使用100%的标准C代码编写的，跨平台当然很好移植和使用。
官方还有模拟器 emWin(UCGUI)模拟器。在电脑上有模拟器啊，这是不是很赞。
且图形界面可以在电脑上拖拽设计，这点儿更赞。
为什么网上没有go语言的ucgui的绑定？于是就萌生了用go语言封装ucgui的想法。
那么既然是为go语言打造的简易GUI,跨平台是必须的吧，至少Windows,linux和嵌入式linux都要支持的吧。
这不，以下先让ucgui在windows上的移植跑起来，是第一步。
ucgui在linux上的移植，参见博文：https://blog.csdn.net/yyz_1987/article/details/78380007
后续计划，ucgui的go语言封装
UCGUI简介：
UCGUI是一种嵌入式应用中的图形支持系统。
它设计用于为任何使用LCD图形显示的应用提供高效的独立于处理器及LCD控制器的图形用户接口。
它适用单任务或是多任务系统环境， 并适用于任意LCD控制器和CPU下任何尺寸的真实显示或虚拟显示。
它的设计架构是模块化的，由不同的模块中的不同层组成，由一个LCD驱动层来包含所有对LCD的具体图形操作。
UCGUI可以在任何的CPU上运行，因为它是100%的标准C代码编写的。
UCGUI能够适应大多数的使用黑白或彩色LCD的应用，它提供非常好的允许处理灰度的颜色管理。
还提供一个可扩展的2D图形库及占用极少RAM的窗口管理体系。
在Windows上的移植：，移植好的demo放在的我的github上了，
地址：https://github.com/yongzhena
https://github.com/yongzhena/ucgui-windows.git
使用方法:
首先，windows上必须有GCC的环境。
推荐安装mingwgcc
我安装的是x86_64-810gcc-posix-seh-npMingw64v75.7z这个压缩包，直接解压。再配置环境变量即可。
跟移植相关的，都在ucgui/GUI_X文件夹中。
在ucgui/GUI文件夹中，有写好的makefile文件，直接make即可编译出libucgui.a库。
然后需要把这个库放到GUIDemo_windows文件夹里。
同时，里面有几个windows上需要依赖的库在里面。libGDI32.LIB,libWINMM.lib,
同时多了两个文件MainTask.c和WinMain.c,其中windows程序的入口在WinMain.c中。
这个里面也有一个makefile文件，可执行make命令，直接就生成了demo，test.exe可执行程序。
