我有一個程序，其中包含跨多個文件完成的多個選項卡，每個文件都有一個文件，我從這里獲得并對其進行了輕微操作，因為它無法用于：主文件import tkinter as tkfrom tkinter import ttkfrom tab1 import *from tab2 import * class MainApplication(tk.Frame): def __init__(self, parent, *args, **kwargs): tk.Frame.__init__(self, parent, *args, **kwargs)notebook = ttk.Notebook(parent)Typ1frame = Typ1(notebook)Typ2frame = Typ2(notebook)notebook.add(Typ1frame, text='TAB1')notebook.add(Typ2frame, text='TAB2')notebook.pack()if __name__ == "__main__": root = tk.Tk() MainApplication(root).pack(side="top", fill="both", expand=True) root.mainloop()表1.pyimport tkinter as tkfrom tkinter import ttkclass Typ1(tk.Frame): def __init__(self, parent, *args, **kwargs): tk.Frame.__init__(self, parent, *args, **kwargs) shell_frame=tk.LabelFrame(self, text="Sample Label Frame", padx=5,pady=5) shell_frame.grid(row=0,column=0,padx=5,pady=5)tab2.pyimport tkinter as tkfrom tkinter import ttkclass Typ2(tk.Frame): def __init__(self, parent, *args, **kwargs): tk.Frame.__init__(self, parent, *args, **kwargs) shell_frame=tk.LabelFrame(self, text="Sample Label Frame", padx=5,pady=5) shell_frame.grid(row=0,column=0,padx=5,pady=5)現在我想用這個程序做一個像頁面一樣的登錄，一旦用戶登錄它就會改變同一頁面上的框架，然后用選項卡顯示如上所示的程序。我曾嘗試查看其他具有多個框架的代碼段并將其放入我的代碼中，但是每次出現網格和包裝等錯誤時，空白框或窗口都是分開的。如果可能，登錄頁面可以是它自己的文件。我會怎么做，或者你能給我一些關于如何自己解決這個問題的線索嗎？提前致謝。

原來你的問題是一個簡單的大小問題。該LabelFrame基本上坐在零大小，因為你還沒有添加任何東西的框架。因此，要糾正此添加寬度和高度以調整大小LabelFrame并解決吊臂問題。
一旦您開始LabelFrame使用小部件填充那些's ，您將不再需要大小格式。
import tkinter as tk
from tkinter import ttk
class MainApplication(tk.Frame):
def __init__(self, parent, *args, **kwargs):
tk.Frame.__init__(self, parent, *args, **kwargs)
notebook = ttk.Notebook(parent)
notebook.add(Typ1(notebook), text='TAB1')
notebook.add(Typ2(notebook), text='TAB2')
notebook.pack()
class Typ1(tk.Frame):
def __init__(self, parent, *args, **kwargs):
tk.Frame.__init__(self, parent, *args, **kwargs)
shell_frame=tk.LabelFrame(self, text="Sample Label Frame", padx=5, pady=5, width=200, height=200)
shell_frame.grid(row=0,column=0,padx=5,pady=5)
class Typ2(tk.Frame):
def __init__(self, parent, *args, **kwargs):
tk.Frame.__init__(self, parent, *args, **kwargs)
shell_frame=tk.LabelFrame(self, text="Sample Label Frame", padx=5,pady=5, width=200, height=200)
shell_frame.grid(row=0,column=0,padx=5,pady=5)
if __name__ == "__main__":
root = tk.Tk()
MainApplication(root).pack(side="top", fill="both", expand=True)
root.mainloop()

您也可以簡單地繼承 fromLabelFrame而不是Frame在您的班級中，以更少的費用獲得相同的結果。
例子：
import tkinter as tk
from tkinter import ttk
class MainApplication(tk.Frame):
def __init__(self, parent, *args, **kwargs):
tk.Frame.__init__(self, parent, *args, **kwargs)
notebook = ttk.Notebook(parent)
notebook.add(Typ1(notebook), text='TAB1')
notebook.add(Typ2(notebook), text='TAB2')
notebook.pack()
class Typ1(tk.LabelFrame):
def __init__(self, parent, *args, **kwargs):
tk.LabelFrame.__init__(self, parent, text="Sample Label Frame", padx=5, pady=5, width=200, height=200)
self.grid(row=0,column=0,padx=5,pady=5)
class Typ2(tk.LabelFrame):
def __init__(self, parent, *args, **kwargs):
tk.LabelFrame.__init__(self, parent, text="Sample Label Frame", padx=5, pady=5, width=200, height=200)
self.grid(row=0,column=0,padx=5,pady=5)
if __name__ == "__main__":
root = tk.Tk()
MainApplication(root).pack(side="top", fill="both", expand=True)
root.mainloop()
要在下面回答您的評論，您將如何將框架交換與登錄頁面集成在一起。
import tkinter as tk
from tkinter import ttk
class App(tk.Tk):
def __init__(self):
tk.Tk.__init__(self)
self._frame = None
self.switch_frame(LoginPage)
def switch_frame(self, frame_class):
"""Destroys current frame and replaces it with a new one."""
new_frame = frame_class(self)
if self._frame is not None:
self._frame.destroy()
self._frame = new_frame
self._frame.grid(row=0, column=0)
class LoginPage(tk.Frame):
def __init__(self, master):
tk.Frame.__init__(self, master)
self.master = master
tk.Label(self, text="Username: ").grid(row=0, column=0)
tk.Label(self, text="Password: ").grid(row=1, column=0)
self.un_entry = tk.Entry(self)
self.un_entry.grid(row=0, column=1)
self.pw_entry = tk.Entry(self)
self.pw_entry.grid(row=1, column=1)
self.pw_entry.bind("<Return>", self.check_login)
tk.Button(self, text="Login", command=self.check_login).grid(row=2, column=0)
def check_login(self, event=None):
if self.un_entry.get() == "Mike" and self.pw_entry.get() == "pass":
self.master.switch_frame(MainApplication)
class MainApplication(tk.Frame):
def __init__(self, parent, *args, **kwargs):
tk.Frame.__init__(self, parent, *args, **kwargs)
notebook = ttk.Notebook(parent)
notebook.add(Typ1(notebook), text='TAB1')
notebook.add(Typ2(notebook), text='TAB2')
notebook.grid(row=0, column=0)
class Typ1(tk.LabelFrame):
def __init__(self, parent, *args, **kwargs):
tk.LabelFrame.__init__(self, parent, text="Sample Label Frame", padx=5, pady=5, width=200, height=200)
self.grid(row=0,column=0,padx=5,pady=5)
class Typ2(tk.LabelFrame):
def __init__(self, parent, *args, **kwargs):
tk.LabelFrame.__init__(self, parent, text="Sample Label Frame", padx=5, pady=5, width=200, height=200)
self.grid(row=0,column=0,padx=5,pady=5)
if __name__ == "__main__":
App().mainloop()
