Question

from tkinter import *

window = Tk()

ia_answers= "trolol"
input_frame = LabelFrame(window, text="User :", borderwidth=4)
input_frame.pack(fill=BOTH, side=BOTTOM)

input_user = StringVar()
input_field = Entry(input_frame, text=input_user)
input_field.pack(fill=BOTH, side=BOTTOM)

ia_frame = LabelFrame(window, text="Discussion",borderwidth = 15, height = 100, width = 100)
ia_frame.pack(fill=BOTH, side=TOP)

user_says = StringVar()
user_text = Label(ia_frame, textvariable=user_says, anchor = NE, justify =   RIGHT, bg="white") 
user_text.pack(fill=BOTH, side=TOP) 

ia_says = StringVar()
ia_text = Label(ia_frame, textvariable=ia_says, anchor = W, justify = LEFT, bg="white") 
ia_text.pack(fill=BOTH, side=BOTTOM) 

def Enter_pressed(event):
    """Took the current string in the Entry field."""
    input_get = input_field.get()
    input_user.set("")
    user_says.set(input_get + "\n\n")
    ia_says.set(ia_answers)

input_field.bind("<Return>", Enter_pressed)
window.mainloop()

嗨，我正在尝试建立一个讨论Bot。

当我执行代码时，输​​入字段中的问题和答案会正确显示。

问题是在输入下一句后，上一个问题/答案被删除。这是一个例子：

Hello Bot
Hello User
(then the text disappears)
How are you
Fine thank you

我想要的是什么：

Hello Bot
Hello User
(then the text stays in the frame)
How are you
Fine thank you

Answer 1

问题出现在行 -

user_says.set(input_get + "\n\n")
ia_says.set(ia_answers)

您将替换users_says.set()并ia_says.set()使用新值重置整个标签。相反，您应该获取旧值并将新值附加到它并将其重新设置，例如 -

user_says.set(user_says.get() + input_get + "\n")
ia_says.set(ia_says.get() + ia_answers + "\n")

或者您也可以为每个新活动创建一个新标签，并将其添加到LabelFrame。示例 -

from tkinter import *

window = Tk()

ia_answers= "trolol\n"
input_frame = LabelFrame(window, text="User :", borderwidth=4)
input_frame.pack(fill=BOTH, side=BOTTOM)

input_user = StringVar()
input_field = Entry(input_frame, text=input_user)
input_field.pack(fill=BOTH, side=BOTTOM)

ia_frame = LabelFrame(window, text="Discussion",borderwidth = 15, height = 100, width = 100)
ia_frame.pack(fill=BOTH, side=TOP)

user_says = StringVar()
user_text = Label(ia_frame, textvariable=user_says, anchor = NE, justify =   RIGHT, 

bg="white") 
user_text.pack(fill=X) 

ia_says = StringVar()
ia_text = Label(ia_frame, textvariable=ia_says, anchor = NW, justify = LEFT, bg="white") 
ia_text.pack(fill=X) 

user_texts = []
ia_texts = []
user_says_list = []
ia_says_list = []
def Enter_pressed(event):
    """Took the current string in the Entry field."""
    input_get = input_field.get()
    input_user.set("")
    user_says1 = StringVar()
    user_says1.set(input_get + "\n")
    user_text1 = Label(ia_frame, textvariable=user_says1, anchor = NE, justify =   RIGHT, 

bg="white") 
    user_text1.pack(fill=X)
    user_texts.append(user_text1)
    user_says_list.append(user_says1)
    ia_says1 = StringVar()
    ia_says1.set(ia_answers)
    ia_text1 = Label(ia_frame, textvariable=ia_says1, anchor = NW, justify = LEFT, 

bg="white") 
    ia_text1.pack(fill=X)
    ia_texts.append(ia_text1)
    ia_says_list.append(ia_says1)

input_field.bind("<Return>", Enter_pressed)
window.mainloop()
