我声明我正在尝试应用此处提出的解决方案Solution by Brad，以便创建更多帧但我无法输入代码和我在控制台中收到的错误。
import Tkinter as tk

TITLE_FONT = ("Helvetica", 18, "bold")
class SampleApp(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)

self.frames[F] = frame
frame.grid(row=0, column=0, sticky="nsew")
self.show_frame(StartPage)

app = SampleApp()
app.mainloop()
这是我要创建的第二页
import Tkinter as tk
import GUIprova
TITLE_FONT = ("Helvetica", 18, "bold")
class PageTwo(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
label = tk.Label(self, text="This is page two", font=TITLE_FONT)
label.place(x=0,y=0,width=592,height=44)
button1 = tk.Button(self, text="Go to Start Page",
command=lambda: SampleApp.show_frame(GUIprova.StartPage))
button3 = tk.Button(self, text="Exit",
command=self.quit)
button1.place(x=100,y=406,width=200,height=44)
button3.place(x=300,y=406,width=200,height=44)
这是例外
Tkinter回调中的异常回溯（最近一次调用最后一次）：
文件 ＆＃34; /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk/Tkinter.py" ;, 第1541行，通话 return self.func（* args）File＆＃34; /Users/Antonello/PycharmProjects/GUI/secondpage.py" ;,第19行，in command = lambda：SampleApp.show_frame（StartPage））TypeError：必须使用SampleApp实例调用未绑定方法show_frame（） 第一个参数（改为使用classobj实例）
答案 0 :(得分：0)
将一个函数和一个调用它的按钮添加到其中一个类（PageOne）的示例，但您应该能够自己解决这个问题。
