python - 如何使用 tkinter 创建聊天窗口？

Question

我试图创建一个聊天窗口，但它无法正常工作。每次我输入消息时，它都会弹出并增加窗口。我该怎么办？

from Tkinter import *

window = Tk()

input_user = StringVar()
input_field = Entry(window, text=input_user)
input_field.pack(side=BOTTOM, fill=X)

def Enter_pressed(event):
    input_get = input_field.get()
    print(input_get)
    label = Label(window, text=input_get)
    input_user.set('')
    label.pack()
    return "break"

frame = Frame(window, width=300, height=300)
input_field.bind("<Return>", Enter_pressed)
frame.pack()

window.mainloop()

您每次按回车键都会添加一个标签，请尝试在 Text 中显示消息小部件:

from Tkinter import *

window = Tk()

messages = Text(window)
messages.pack()

input_user = StringVar()
input_field = Entry(window, text=input_user)
input_field.pack(side=BOTTOM, fill=X)

def Enter_pressed(event):
    input_get = input_field.get()
    print(input_get)
    messages.insert(INSERT, '%s\n' % input_get)
    # label = Label(window, text=input_get)
    input_user.set('')
    # label.pack()
    return "break"

frame = Frame(window)  # , width=300, height=300)
input_field.bind("<Return>", Enter_pressed)
frame.pack()

window.mainloop()
