我正在为欺凌/滥用项目编写一个“热线”程序，共有4页：首页/欺凌/虐待/其他和顶部栏。我正在按按钮进入其他页面，但是每次都会有不同的错误。
我已经尝试过从页面和容器中执行提升命令，以及在其中编程的显示命令。两者均无效。 （顺便说一下，代码并非全部属于我，其中大部分是来自Caspar Wylie的问题Using buttons in Tkinter to navigate to different pages of the application?）
import tkinter as tk
class Page(tk.Frame):
def __init__(self, *args, **kwargs):
tk.Frame.__init__(self, *args, **kwargs)
def show(self):
self.lift()
class Page1(Page):
def __init__(self, *args, **kwargs):
Page.__init__(self, *args, **kwargs)
label = tk.Label(self, text="Welcome to the Help Hotline! Please select your concern.", relief = 'groove')
label.grid(row = 0, column = 1, columnspan = 3, sticky = 'nesw', padx = 5, pady = 5)
bullybutton = tk.Button(self, text = "Bullying", command = MainView.p2.lift)
bullybutton.grid(row = 1, column = 1, padx = 5, pady = 5, sticky = 'nsew')
abusebutton = tk.Button(self, text = "Abuse", command = MainView.p3.lift)
abusebutton.grid(row = 1, column = 2, padx = 5, pady = 5, sticky = 'nsew')
otherbutton = tk.Button(self, text = "Other", command = MainView.p4.lift)
otherbutton.grid(row = 1, column = 3, padx = 5, pady = 5, sticky = 'nsew')
class Page2(Page):
def __init__(self, *args, **kwargs):
Page.__init__(self, *args, **kwargs)
label = tk.Label(self, text="This is page 2")
label.grid(row = 0, column = 1, sticky = 'nesw', padx = 5, pady = 5)
class Page3(Page):
def __init__(self, *args, **kwargs):
Page.__init__(self, *args, **kwargs)
label = tk.Label(self, text="This is page 3")
label.grid(row = 0, column = 1, sticky = 'nesw', padx = 5, pady = 5)
class Page4(Page):
def __init__(self, *args, **kwargs):
Page.__init__(self, *args, **kwargs)
label = tk.Label(self, text="This is page 4")
label.grid(row = 0, column = 1, sticky = 'nesw', padx = 5, pady = 5)
class MainView(tk.Frame):
def __init__(self, *args, **kwargs):
tk.Frame.__init__(self, *args, **kwargs)
p1 = Page1(self)
p2 = Page2(self)
p3 = Page3(self)
p4 = Page4(self)
container = tk.Frame(self)
container.pack(side="top", fill="both", expand=True)
p1.place(in_=container, x=0, y=0, relwidth=1, relheight=1)
p2.place(in_=container, x=0, y=0, relwidth=1, relheight=1)
p3.place(in_=container, x=0, y=0, relwidth=1, relheight=1)
p4.place(in_=container, x=0, y=0, relwidth=1, relheight=1)
menubar = tk.Menu(root)
filemenu = tk.Menu(menubar, tearoff=0)
filemenu.add_command(label="Home", command=p1.lift)
filemenu.add_command(label="Bullying", command=p2.lift)
filemenu.add_command(label="Abuse", command=p3.lift)
filemenu.add_command(label="Other", command=p4.lift)
filemenu.add_separator()
filemenu.add_command(label="Quit", command=exit)
menubar.add_cascade(label="Navigate", menu=filemenu)
root.config(menu=menubar)
p1.show()
root = tk.Tk()
root.geometry('500x500')
main = MainView(root)
main.pack(side="top", fill="both", expand=True)
root.title("Bullying and Abuse Hotline")
root.mainloop()
我希望有3个按钮，每个按钮都转到各自的页面，但我收到有关“无属性tk”或“缺少参数自变量”或根本没有变化的错误。
答案 0 :(得分：1)
这是对代码的（相当专业的）重做，我认为它可以完成您想要的事情。您没有提供与Caspar Wylie的问题的链接，所以我大量借鉴了Bryan Oakley开创性的answer中显示的技术，该问题Switch between two frames in tkinter的作用非常相似，尽管没有菜单（但最后确实包含许多可能非常有用的链接）。
更新
我自己找到了Caspar Wylie的问题，并在您的问题中添加了链接，并对以下代码进行了一些修改，以使其与相关的答案更加一致（恰好也是Bryan编写的）。
