【问题描述】：

import tkinter as tk
from tkinter import *
import time


def centertitle(e):
    w = int(root.winfo_width() / 3.5)
    s = 'Installation Wizard v1.0'.rjust(w//2)
    root.title(s)

def textbox():
    textbox=Text(root.canvas, width = 62, height = 25, state=DISABLED)
    textbox.pack()
    textbox.insert(constants.INSERT,'You text goes here')

#Configure tkinter window and title
root = Tk()
root.canvas = Canvas(root, width = 500, height = 404, bg="#3D3D3D", highlightthickness=0)
root.canvas.pack(expand=True, fill=BOTH)

root.iconbitmap(default='transparent.ico')  
root.bind("<Configure>", centertitle)
root.resizable(False, False)

#Buttons
btn = tk.Button(root, text='Start Install', height = 2, width = 15)
btn['command'] =  lambda b=btn:[b.pack_forget(), b.place_forget(), textbox()]
btn.pack(fill=BOTH)
btn.place(x=190, y=181)

root.mainloop()

我试图创建的是一个简单的“安装”gui，我打算将它打包到一个 exe 中。我真正想要的是一个按钮，它启动另一个python文件（安装所有东西的那个），当它调用打印时，我希望它发送到gui中的文本框......这很难解释，但我希望你明白我的意思是

有人可以帮助我，我真的对 guis 感到困惑

来自其他 .py 的代码：

【问题讨论】：

为什么会有两段代码？ other.py 的目的是什么？第一个代码块没有引用它。请尽量只有一个代码块以避免混淆。
为什么要将Text 小部件放在Canvas 中？此外，虽然Text 小部件的state 是"disabled"，但没有人不能编辑它的内容。这包括你。使用.config(state="normal") 然后尝试插入您的文本

标签： python user-interface tkinter

【解决方案1】：

您已将文本小部件的状态设置为禁用，因此您无法向其中插入任何内容。如果您希望禁用它，请在插入文本之后而不是之前禁用它。

def textbox():
    textbox=Text(root.canvas, width = 62, height = 25)
    textbox.pack()
    textbox.insert(constants.INSERT,'You text goes here')
    textbox.configure(state=DISABLED)
