在我的程序中，我想添加很多標簽，并且要查看所有標簽，它們需要滾動條。如果我在代碼中添加滾動條，那么所有標簽都會消失。我對長代碼表示歉意，由于某種原因，如果沒有所有額外的代碼，我就無法讓它工作。沒有滾動條的代碼：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)

我在這里看到兩個問題，第一個問題是您嘗試用于.grid顯示文本的標簽，并用于.pack滾動條。您不能在同一窗口中同時使用.grid和。.pack
.grid(row=index, column=0)這是我通過替換來糾正此問題的代碼.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()
第二個問題是滾動條實際上沒有用。我不相信滾動條本身就可以在 tkinter 中的窗口/框架上工作。這意味著修復原始問題后，標簽和滾動條現在都會加載，但滾動條不會執行任何操作。
