ucgui在windows上的移植,及为go语言打造简易跨平台GUI的想法

2020-08-04 10:44:53 浏览数 (1)

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。
