在科创上许多都需要使用gui界面。虽然不知道大家用什么方式制作,但我自认为用Qt加python还是很好用的。
首先需要用到这个Qtcreator
打开后 文件>新建 >在左边那列选Qt然后右边选第三个点>“确定”
然后只要把左边那列的控件拖到中间你想要的相应位置即可
按Alt+Shift+R可以进行预览 ,全部弄完后保存得到一个 .ui 文件
最后就是将ui文件转为.py文件了。我的工具隆重登场!

打包后有点大,就把python代码放这了,大家下好相应的库就可以直接运行。

对懒人来说,C/C++才是王道
服务器、上位机和各种单片机用同一套库,同一套API,不管多复杂的数据结构传输直接memcpy
pyQT也提供了一个编译的指令,也可以实现直接把ui文件转换成py文件,我的sublime自动编译指令配置如下:
{
"cmd": ["pyuic5", "-o", "${file_base_name}.py", "$file_name"],
"selector": "source.ui",
"working_dir": "$file_path",
}
CS出身,这个叫做qt的py绑定-pyqt.但是看到你的代码里又混入了另一套GUI框架-tkinter.。。有点换乱哦,单独用pyqt就行了。
