python使用tkinter编写一个数据显示窗口(实时显示更新的数据)

本文主要是介绍python使用tkinter编写一个数据显示窗口(实时显示更新的数据),对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

以下代码为python3版本,python2版本使用需保证更新数据的那部分代码处于主进程中,如果放在线程中会出现错误,所以建议能用 python3就用python3,只用我为什么知道python2会出现这个问题,那就是ros没python3的版本…

示意图(数据就会在后面的框里面通过程序运行时的值的改变而改变):
在这里插入图片描述
以下为代码,我这里在下面提供两个代码示例:

1.(第一部分)修改为可以直接运行显示,但注释掉了刷新数据的线程部分的,无法对数据进行更新。

"""注意这个 窗口拉起接口在 一 二 部分中被调用的不同的写法"""
self.main_window.mainloop()

2.(第二部分)没有注释掉线程部分,需要通过 from import 的方法在另外一个py文件的线程中进行调用更新,下面是我截取的部分在另一个py文件中的调用,示例

from hint_window import m_win


 def t_correct(self):
        t_correct = threading.Thread(target=self.calculate_instant_speed)
        t_correct.setDaemon(True)
        t_correct.start()
  def calculate_instant_speed(self):
        """用于更新瞬时速度"""
        """
        self.x_speed ,self.y_speed, self.p_speed
        """
        

            m_win.updata_node("vx", self.x_speed)
            m_win.updata_node("vy", self.y_speed)
            m_win.updata_node("vw", self.p_speed)
