text_frame.place() 不显示文本框

Question

尝试显示文本框，使用 .pack() 显示，但 .place() 未显示。由于填充，我不想使用 .pack() ；由于relx和rely，我宁愿使用.place()。

import tkinter as tk
from tkinter import messagebox
import time


def typewriter_effect(text_widget, text, buttons):
    for button in buttons:
        button.place_forget()  # Hide buttons while typing
    for char in text:
        text_widget.insert(tk.END, char)
        text_widget.see(tk.END)
        text_widget.update()
        time.sleep(0.05)
    for button in buttons:
        button.place(relx=0.5, rely=0.5, anchor=tk.CENTER)  # Show buttons after typing

def explore_room():
    messagebox.showinfo("Exploration", "You explored the room. You found a key!")

def go_back_to_sleep():
    messagebox.showinfo("Back to Sleep", "You went back to sleep. Zzz...")

def look_for_light_switch():
    messagebox.showinfo("Light Switch", "You found the light switch. The room is now illuminated.")

def main():
    root = tk.Tk()
    root.title("Text Adventure Game")
    root.attributes("-fullscreen", True)

    text_options_frame = tk.Frame(root, bd=2, relief=tk.RIDGE)
    text_options_frame.pack(expand=True)

    text_frame = tk.Frame(text_options_frame, bd=0)
    text_frame.place(relx=0.5, rely=0.7, anchor=tk.CENTER)  # Placing at the bottom center

    text_scroll = tk.Scrollbar(text_frame)
    text_scroll.pack(side=tk.RIGHT, fill=tk.Y)

    text_widget = tk.Text(text_frame, wrap=tk.WORD, yscrollcommand=text_scroll.set, height=10, width=120, font=("Helvetica", 12))
    text_widget.pack(fill=tk.BOTH, expand=True)

    text_scroll.config(command=text_widget.yview)

    button_frame = tk.Frame(root)
    button_frame.pack(side=tk.BOTTOM, pady=10)

    explore_button = tk.Button(button_frame, text="Explore the room", command=explore_room)
    sleep_button = tk.Button(button_frame, text="Go back to sleep", command=go_back_to_sleep)
    light_button = tk.Button(button_frame, text="Look for a light switch", command=look_for_light_switch)

    typewriter_effect(text_widget, "Welcome to the Text Adventure Game!\n\n"
                                    "You find yourself in a dark room. What would you like to do?\n",
                                    [explore_button, sleep_button, light_button])
    
    delay([explore_button, sleep_button, light_button], 1)
    explore_button.pack(side=tk.LEFT, padx=5)
    sleep_button.pack(side=tk.LEFT, padx=5)
    light_button.pack(side=tk.LEFT, padx=5)
    delay([explore_button], 1)
    explore_button.pack_forget()
    root.mainloop()


def delay(button, wait):
    for widget in button:
        widget.update()
    time.sleep(wait)

if __name__ == "__main__":
    main()

尝试使用 .place() 但文本框不会显示，似乎文本正在文本框中写入，因为按钮设置为在文本写入完成后出现。

text_frame.place() 不显示文本框

尝试显示文本框，使用 .pack() 显示，但是 .place() 没有生成。由于填充，我不想使用 .pack() ； 我宁愿使用 .place() 因为 relx 和依赖

问题可以解决。

注释掉

main()

函数中的第32行和33行。

使用

text_frame

作为

Text

小部件。

我为背景和前景添加了颜色。这样，我们就可以确定框架位置了。

片段：

def main():
    root = tk.Tk()
    root.title("Text Adventure Game")
    root.attributes("-fullscreen", True)   

    #text_options_frame = tk.Frame(root, bd=2, relief=tk.RIDGE)
    #text_options_frame.pack(expand=True)

    text_frame = tk.Frame(root, bd=2, relief=tk.RIDGE)
    text_frame.place(relx=0.63, rely=0.7, anchor=tk.CENTER)  # Placing at the bottom center

    text_scroll = tk.Scrollbar(text_frame)
    text_scroll.pack(side=tk.RIGHT, fill=tk.Y)

    text_widget = tk.Text(text_frame, wrap=tk.WORD, bg='blue', fg='white', yscrollcommand=text_scroll.set, height=10, width=120, font=("Helvetica", 12))
    text_widget.pack(fill=tk.BOTH, expand=True)
