我正在制作一个包含多个页面的 tkinter 应用程序。我使用的代码的简单版本如下所示。我将菜单添加到应用程序的根目录，并提供了一个文件选项以及“重新加载默认值”和“退出”子选项。
当我运行这段代码时，我确实得到了菜单，但不是在 GUI 上，而是在 Mac 的主菜单栏上。而且菜单没有反应。我不确定我做错了什么！
import tkinter as tk
from tkinter import ttk
from tkinter import RAISED
LARGEFONT =("Verdana", 35)
class tkinterApp(tk.Tk):
# __init__ function for class tkinterApp
def __init__(self, *args, **kwargs):
# __init__ function for class Tk
tk.Tk.__init__(self, *args, **kwargs)
# creating a container
container = tk.Frame(self)
container.pack(side = "top", fill = "both", expand = True)
container.grid_rowconfigure(0, weight = 1)
container.grid_columnconfigure(0, weight = 1)
container2 = tk.Frame(self, relief=RAISED, borderwidth=2)
container2.pack(side="bottom",fill="both", expand=True)
container2.grid_rowconfigure(0, weight = 1)
container2.grid_columnconfigure(0, weight = 1)
def runProg():
print("response from runProg")
#get all entry value from page 2
runButton = ttk.Button(container2, text="Run", command=runProg)
runButton.pack(side="left", padx=5, pady=5)

## Menu items

self.config(menu=progMenu)
#create File menu
def reload_command():
pass
fileMenu = tk.Menu(progMenu)
progMenu.add_cascade(label="File", menu=fileMenu)
fileMenu.add_command(label="Reload Defaults", command=reload_command)
fileMenu.add_command(label="Exit", command=reload_command)

# initializing frames to an empty array
self.frames = {}
frame = StartPage(container, self)
self.frames[StartPage] = frame
frame.grid(row = 0, column = 0, sticky ="nsew")
self.show_frame(StartPage)
# to display the current frame passed as
# parameter
def show_frame(self, cont):
frame = self.frames[cont]
frame.tkraise()
# first window frame startpage
class StartPage(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
# label of frame Layout 2
label = ttk.Label(self, text ="Startpage", font = LARGEFONT)
# putting the grid in its place by using
# grid
label.grid(row = 0, column = 2, padx = 10, pady = 10)
app = tkinterApp()
app.mainloop()
任何帮助将不胜感激！
