【飞凌RK3568开发板试用体验】tkinter的第一个桌面程序

准备用python3做图形界面的开发，了解有如下几种工具：

• Tkinter :是python最简单的图形化模块，总共只有14种组建;
• Pyqt :是python最复杂也是使用最广泛的图形化;
• Pyside:好象是替代pyqt;
• Wx :是python当中居中的一个图形化，学习结构很清晰
• Pywin :是python windows 下的模块，摄像头控制(opencv)，常用于外挂制作；
  原来用过pyqt5\pyside2\pyside5。
  由于这几天安装都比较麻烦。所以这次用tkinter来做。
  用pip3 install tkinter是安装不了的。要使用apt install python3-tk来安装：

forlinx@ok3568:~$ sudo apt install python3-tk

The following packages were automatically installed and are no longer required:
  libpython2-stdlib libpython2.7-minimal libpython2.7-stdlib python2
  python2-minimal python2.7 python2.7-minimal
Use 'sudo apt autoremove' to remove them.
Suggested packages:
  tix python3-tk-dbg
The following NEW packages will be installed:
  python3-tk

这样python3 tkinter就安装成功了。注意不要用apt install python-tk，这样就会安装给python2.7的tkinter。
测试一下：

forlinx@ok3568:~$ dpkg --list | grep python3-tk
ii  python3-tk:arm64                              3.8.10-0ubuntu1~20.04               arm64        Tkinter - Writing Tk applications with Python 3.x

新建一个测试程序：

root@ok3568:~/Documents# touch tkinter_demo.py

#!/usr/bin/python3
# -*- coding: UTF-8 -*-

import tkinter

top=tkinter.Tk(className='飞凌OK3568')

#加上标签
label = tkinter.Label(top)
label['text'] = '电子发烧友、飞凌OK3568进行python测试'


#加上按钮
button = tkinter.Button(top)
button['text'] = '点一下'
button.pack()


label.pack()


#进入消息循环体
top.mainloop()

然后python3 tkinter_demo.py就启动了飞凌OK3568的第一个窗口程序。
