Question

考虑到这个问题的接受答案：

Using buttons in Tkinter to navigate to different pages of the application?

有没有办法扩展Page类，以便可以从MainView初始化任意数量的页面，而不必为每个单独的页面创建一个新类？

谢谢！

该示例的重点是展示如何在不同页面之间切换。我没有完全看到有多个完全相同的页面。

话虽如此，没有什么可以阻止您根据需要创建单个页面的实例。这里对您链接的答案略有修改，这会创建十个相同的页面并让您在它们之间循环：

import Tkinter as tk

class Page(tk.Frame):
    def __init__(self, title):
        tk.Frame.__init__(self, bd=1, relief="sunken")
        self.label = tk.Label(self, text=title)
        self.label.pack(side="top", fill="both", expand=True)

    def show(self):
        self.lift()

class MainView(tk.Frame):
    def __init__(self, *args, **kwargs):
        tk.Frame.__init__(self, *args, **kwargs)

        buttonframe = tk.Frame(self)
        container = tk.Frame(self)

        buttonframe.pack(side="top", fill="x", expand=False)
        container.pack(side="top", fill="both", expand=True, padx=2, pady=2)

        next_button = tk.Button(buttonframe, text=" > ", command=self.next_page)
        prev_button = tk.Button(buttonframe, text=" < ", command=self.prev_page)
        prev_button.pack(side="left")
        next_button.pack(side="left")

        self.pages = []
        for i in range(10):
            page = Page(title="page %d" % i)
            page.place(in_=container, x=0, y=0, relwidth=1, relheight=1)
            self.pages.append(page)

        self.pages[0].show()

    def next_page(self):
        # move the first page to the end of the list, 
        # then show the first page in the list
        page = self.pages.pop(0)
        self.pages.append(page)
        self.pages[0].show()

    def prev_page(self):
        # move the last page in the list to the front of the list,
        # then show the first page in the list.
        page = self.pages.pop(-1)
        self.pages.insert(0, page)
        self.pages[0].show()


if __name__ == "__main__":
    root = tk.Tk()
    main = MainView(root)
    main.pack(side="top", fill="both", expand=True)
    root.wm_geometry("400x400")
    root.mainloop()
