Python gui编程

Question

import tkinter as tk
from tkinter import messagebox

class App(tk.Frame):
  def __init__(self, master=None):
    super().__init__(master)
    self.master = master
    self.pack()
    self.creatWight()


  def creatWight(self):
    self.w1 = tk.Text(self, width=40, height=10, bg="gray")
    self.w1.pack()
    self.w1.insert(1.0, "123456789\nabcdefg")
    self.w1.tag_add("good", 1.0, 1.9)


if __name__ == '__main__':
  root = tk.Tk()
  root.title("GUI")
  root.geometry("300x400+200+200")
  app = App(master=root)
  root.mainloop()

运行之后，为什么标签添加不上去？

Answer 1

标签的作用是给设定的区间添加一些自定制设置，比如字体大小，颜色，背景色等等，并不是插入操作

 
 
  def creatWight(self):
    self.w1 = tk.Text(self, width=40, height=10, bg="gray")
    self.w1.pack()
    self.w1.insert(1.0, "123456789\nabcdefg")
    self.w1.tag_add("good", 1.0, 1.9)
    self.w1.tag_config("good",background='red')
