如果我添加滾動(dòng)條，所有標(biāo)簽都會(huì)消失

Python

在我的程序中，我想添加很多標(biāo)簽，并且要查看所有標(biāo)簽，它們需要滾動(dòng)條。如果我在代碼中添加滾動(dòng)條，那么所有標(biāo)簽都會(huì)消失。我對(duì)長(zhǎng)代碼表示歉意，由于某種原因，如果沒(méi)有所有額外的代碼，我就無(wú)法讓它工作。沒(méi)有滾動(dòng)條的代碼：from tkinter import *from functools import partialwords = ["test", "test", "test", "test", "test", "test", "test", "test", "test", "test", "test", "test", "test", "test"]def validateLogin(password): print(password.get()) if password.get() == "test": newWindow = Tk() newWindow.geometry('1800x800') newWindow.title("Passwords") tkWindow.destroy() for index, word in enumerate(words): Label(newWindow, text=word).grid(row=index, column=0) if password.get() != "test": Label(tkWindow, text="Wrong password!", fg='red').grid(row=5, column=2)#windowtkWindow = Tk()tkWindow.geometry('250x100')tkWindow.title('Passwords')#password label and password entry boxpasswordLabel = Label(tkWindow,text="Password").grid(row=1, column=0)password = StringVar()passwordEntry = Entry(tkWindow, textvariable=password, show='*').grid(row=1, column=2)validateLogin = partial(validateLogin, password)#login buttonloginButton = Button(tkWindow, text="Login", command=validateLogin).grid(row=4, column=2)tkWindow.mainloop()帶滾動(dòng)條的代碼：from tkinter import *from functools import partialwords = ["test", "test", "test", "test", "test", "test", "test", "test", "test", "test", "test", "test", "test", "test"]def validateLogin(password): print(password.get()) if password.get() == "test": newWindow = Tk() newWindow.geometry('1800x800') newWindow.title("Passwords") scrollbar = Scrollbar(newWindow) scrollbar.pack(side=RIGHT, fill=Y) tkWindow.destroy() for index, word in enumerate(words): Label(newWindow, text=word).grid(row=index, column=0) if password.get() != "test": Label(tkWindow, text="Wrong password!", fg='red').grid(row=5, column=2)

我在這里看到兩個(gè)問(wèn)題，第一個(gè)問(wèn)題是您嘗試用于.grid顯示文本的標(biāo)簽，并用于.pack滾動(dòng)條。您不能在同一窗口中同時(shí)使用.grid和。.pack

.grid(row=index, column=0)這是我通過(guò)替換來(lái)糾正此問(wèn)題的代碼.pack(anchor = W)

from tkinter import *

from functools import partial

words = ["test", "test", "test", "test", "test", "test", "test", "test", "test", "test", "test", "test", "test", "test"]

def validateLogin(password):

? ? print(password.get())

? ? if password.get() == "test":

? ? ? ? newWindow = Tk()

? ? ? ? newWindow.geometry('1800x800')

? ? ? ? newWindow.title("Passwords")

? ? ? ? scrollbar = Scrollbar(newWindow)

? ? ? ? scrollbar.pack(side=RIGHT, fill=Y)

? ? ? ? tkWindow.destroy()

? ? ? ? for index, word in enumerate(words):

? ? ? ? ? ? Label(newWindow, text=word).pack(anchor = W)

? ? if password.get() != "test":

? ? ? ? Label(tkWindow, text="Wrong password!", fg='red').grid(row=5, column=2)

#window

tkWindow = Tk()

tkWindow.geometry('250x100')

tkWindow.title('Passwords')

#password label and password entry box

passwordLabel = Label(tkWindow,text="Password").grid(row=1, column=0)

password = StringVar()

passwordEntry = Entry(tkWindow, textvariable=password, show='*').grid(row=1, column=2)

validateLogin = partial(validateLogin, password)

#login button

loginButton = Button(tkWindow, text="Login", command=validateLogin).grid(row=4, column=2)

tkWindow.mainloop()

第二個(gè)問(wèn)題是滾動(dòng)條實(shí)際上沒(méi)有用。我不相信滾動(dòng)條本身就可以在 tkinter 中的窗口/框架上工作。這意味著修復(fù)原始問(wèn)題后，標(biāo)簽和滾動(dòng)條現(xiàn)在都會(huì)加載，但滾動(dòng)條不會(huì)執(zhí)行任何操作。
