Question

我需要测试文本小部件，或者比较文本行中出现的字符的标签，如果用户按下了所需的按钮，这是在 key_type() 函数中。为什么调用 event_generate 时没有插入字符？

import tkinter as tkinter
import unittest
from tkinter import *
import main

class MyGUI(tkinter.Frame):
    def __init__(self, top, **kw):
        super().__init__(top, **kw)
        self.button1 = Button(self, text="Играть",command=lambda: main.command())
        self.button2 = Button(self, text="Выйти",command=lambda: main.command2())
        self.button1.pack()
        self.button2.pack()
        test_text = "Avd"
        self.text_widget = Text(self, height=10, width=100,
                           padx=20, pady=20, font=("Arial ", 16))
        self.text_widget.insert(END, test_text)
        self.text_widget.configure(state="disabled")
        self.text_widget.tag_config("correct", background="green", foreground="white")
        self.text_widget.tag_config("wrong", background="red", foreground="white")

        self.text_widget.bind("<KeyPress>", main.key_type)
        self.text_widget.focus()
        self.text_widget.pack()
class TKinterTestCase(unittest.TestCase):
    def setUp(self):
        self.top = Toplevel()
        self.root2 = Tk()

    def tearDown(self):
        if self.top:
            self.top.destroy()
        if self.root2:
            self.root2.destroy()

    def test_enter1(self):
        v = MyGUI(self.top)
        v.button2.event_generate('<Button-1>')
        self.assertTrue(v.button1.winfo_exists())

    def test_enter2(self):
        v = MyGUI(self.top)
        v.button2.event_generate('<Button-1>')
        self.assertTrue(v.button2.winfo_exists())
        v.text_widget.focus_set()
        v.after(100, lambda: self.root2.event_generate('A'))
        self.assertEqual("correct",v.text_widget.tag_names(1.0))

if __name__ == "__main__":
    unittest.main()

def key_type(e):
    if e.keycode != 16:
        global pos, text_widget, b, mistakes, correct_presses
        if (test_text[pos] != e.char):
            text_widget.tag_add("wrong", str(1) + "." + str(b))
            mistakes += 1
        if (test_text[pos] == e.char):
            text_widget.tag_add("correct", str(1) + "." + str(b))
            correct_presses += 1
        b += 1
        pos += 1

运行测试： '正确' != ()
