在 tkinter python 中销毁框架后未填充可用空间

Question

在我的代码中，当发送消息时，frame1和frame2被销毁。然而，在销毁frame1和frame2之后，消息不会使用这个额外的空间。此外，它们的顶部还有额外的空间。我希望这些消息能够在顶部和底部利用这种额外的节奏。我在第二张图片中用箭头指示了这个额外的空间。 这是我的代码：

import tkinter as tk
from tkinter import ttk

frames_loaded = True

root = tk.Tk()
# Adjust the placement of other widgets accordingly
root.title("Test")
# Maximize the window
root.attributes('-zoomed', True)
style = ttk.Style()
style.theme_use("clam")
chat_frame = tk.Frame(root, bg="white")
chat_frame.pack(expand=True, fill=tk.BOTH)

chat_log = tk.Text(chat_frame, state='disabled', wrap='word', width=70, height=15, font=('Sans-serif', 12), bg="white", fg="black", highlightthickness=0, borderwidth=0)
chat_log.pack(side=tk.LEFT, padx=(500,0), pady=10)

# Create frames to group the boxes
frame1 = tk.Frame(root, bg="white")
frame1.pack(side=tk.TOP, padx=(0, 40), pady=(100, 1))

frame2 = tk.Frame(root, bg="white")
frame2.pack(side=tk.TOP, padx=(0, 40), pady=(5, 20))

style.configure("PDF.TButton", font=('Sans-serif', 12,), background="white", fg="black", highlightthickness=1, highlightbackground="gray", borderwidth=1)
chat_with_pdf_button = ttk.Button(frame1, text="Teyxxxxxxxxxxxx", style="PDF.TButton")
chat_with_pdf_button.pack(side=tk.LEFT, ipadx=(135), padx=(0, 10), ipady=14)

option2_label = tk.Label(frame1, text="testxxxxxxxxxxxxxxxxx", font=('Sans-serif', 12,), bg="white", fg="black", highlightthickness=1, highlightbackground="gray", padx=95, pady=20)
option2_label.pack(side=tk.LEFT)

# Create labels for the options in the second frame
option3_label = tk.Label(frame2, text="testzzzzzzzzzzzzzzzz", font=('Sans-serif', 12,), bg="white", fg="black", highlightthickness=1, highlightbackground="gray", padx=116, pady=20)
option3_label.pack(side=tk.LEFT, padx=(0, 10))

option4_label = tk.Label(frame2, text="testqqqqqqqqqqqqqqqqq", font=('Sans-serif', 12,), bg="white", fg="black", highlightthickness=1, highlightbackground="gray", padx=115, pady=20)
option4_label.pack(side=tk.LEFT)

def append_to_chat_log(sender=None, message=None):
  
    chat_log.config(state=tk.NORMAL)
    if sender:
        chat_log.insert("end", f"{sender}\n\n", "sender")
        
        #chat_log.insert("end",'\n\n')
    if message:
        chat_log.insert("end", message)
    chat_log.tag_config("sender", font=('Arial', 12, 'bold'), foreground="black")
    chat_log.config(state=tk.DISABLED)
    chat_log.see("end")
    chat_log.update()

def send_message(event=None):
    global frames_loaded
    if frame1:
        frame1.destroy()
    if frame2:
        frame2.destroy()
    frames_loaded = False
    message = message_entry.get(1.0, "end-1c") 
    message = message.strip()
    message_entry.delete(1.0, tk.END)
    message_entry.update()
    
    if not message:
        pass 
    else:
        canvas1.place(x=495,y=80)
        canvas1.update()
        
        append_to_chat_log("User")
        append_to_chat_log(message=message)
        append_to_chat_log(message="\n")
        canvas1.place_forget()
        canvas1.update()

canvas1 = tk.Canvas(root, width=250, height=70, bg="white", borderwidth=0, highlightthickness=0)
# Display "Loading" text
loading_text = canvas1.create_text(70, 50, text="Loading...", anchor="e")

message_entry = tk.Text(root, padx=17, insertbackground='white', bg="white", fg="black", width=70, height=1, spacing1=20, spacing3=20, font=('Open Sans', 14))
message_entry.pack(side=tk.LEFT, padx=(500, 0), pady=(0, 70))  # Adjust pady to move it slightly above the bottom
#message_entry.insert(0, "Ask me anything...")
message_entry.insert(1.0, "Type")
message_entry.mark_set("insert", "%d.%d" % (0,0))
message_entry.bind("<Return>", send_message)
root.mainloop()

在 Text

chat_log

对象的包定义中，将其更改为：

chat_log.pack(side=tk.LEFT, padx=(500,0), pady=10, expand = True, fill = tk.BOTH)

这解决了我的问题，希望它也适合你
