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机器人。你知道吗

当我执行代码时，输入字段中的问题和答案会正确显示。你知道吗

问题是在输入下一句话后，上一个问题/答案将被删除。举个例子：

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

我想要的是：

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

Answer 1

问题发生在-

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

您将替换users_says.set()，ia_says.set()并用新值重置完整的标签。相反，您应该获取旧值并将新值附加到它，然后将其设置回原来的值，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事件创建一个新标签，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()
