我使用名为Thonny的python程序。它曾用于制作另一个说“你已经把它变成主要应用程序”的盒子，但我现在删除了那段文字。我希望它显示一个选项按钮和一个更改密码按钮。这是代码：
import tkinter as tk
class Mainframe(tk.Tk):
def __init__(self):
tk.Tk.__init__(self)
self.frame = FirstFrame(self)
self.frame.pack()
def change(self, frame):
self.frame.pack_forget() # delete currrent
frame = frame(self)
self.frame.pack() # make new frame
class FirstFrame(tk.Frame):
def __init__(self, master=None, **kwargs):
tk.Frame.__init__(self, master, **kwargs)
master.title("Enter password")
master.geometry("300x200")
self.status = tk.Label(self, fg='red')
self.status.pack()
lbl = tk.Label(self, text='Enter password')
lbl.pack()
self.pwd = tk.Entry(self, show="*")
self.pwd.pack()
self.pwd.focus()
self.pwd.bind('<Return>', self.check)
btn = tk.Button(self, text="Done", command=self.check)
btn.pack()
btn = tk.Button(self, text="Cancel", command=self.quit)
btn.pack()
def check(self, event=None):
if self.pwd.get() == 'password':
self.master.change(SecondFrame)
else:
self.status.config(text="Wrong password")
class SecondFrame(tk.Frame):
def __init__(self, master=None, **kwargs):
tk.Frame.__init__(self, master, **kwargs)
master.title("Main application")
master.geometry("600x400")
def options_button(self):
def set_password(self):
e = tk.Entry(master, show="*", textvariable=self.password_set2)
e.pack()
but1 = tk.Button(self, text="Done", command=self.password_set)
but1.pack()
b = tk.Button(self, text="Set your password", command=self.set_password)
b.pack()
c = tk.Button(self, text="Options", command=self.options_button)
c.pack()
if __name__=="__main__":
app=Mainframe()
app.mainloop()
