如何僅使用一種功能在不同的幀中顯示結果？

我有這個代碼來更改框架的標題。我這里有兩頁。在PageOne課堂上，我們得到了標題，按下按鈕，標題就會改變。而且，我們可以使用Go to page two按鈕導航到PageTwo. 在這里我們也可以這樣做。

這是我的問題，我如何才能只定義一個函式而不是使用 function add1()inPageOne和 function add2()in PageTwo。我的意思是我只定義一個函式并在PageOne中使用相同的函式PageTwo，并在frame2.

import tkinter as tk


class Data:
    def __init__(self):
        self.number1 = tk.StringVar()
        self.number2 = tk.StringVar()


class SampleApp(tk.Tk):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.minsize(700, 700)
        container = tk.Frame(self)
        container.pack()

        self.data = Data()

        self.frames = {}
        for F in (PageOne, PageTwo):
            frame = F(container, self.data)
            self.frames[F] = frame
            frame.grid(row=0, column=0, sticky="nsew")

        self.frames[PageOne].page_button.config(command=self.go_to_page_two)
        self.show_frame(PageOne)

    def go_to_page_two(self):
        self.show_frame(PageTwo)

    def show_frame(self, c):
        frame = self.frames[c]
        frame.tkraise()


class PageOne(tk.Frame):
    def __init__(self, parent, data):
        super().__init__(parent)
        self.data = data

        entry1 = tk.Entry(self, textvariable=self.data.number1)
        entry1.pack()

        self.button1 = tk.Button(self, text="click", command=self.add1)
        self.button1.pack()

        self.frame1 = tk.LabelFrame(self, height=200, width=200, borderwidth=2)
        self.frame1.pack()

        self.page_button = tk.Button(self, text="Go to Page Two")
        self.page_button.pack()

    def add1(self):
        self.frame1.config(text=str(self.data.number1.get()))


class PageTwo(tk.Frame):
    def __init__(self, parent, data):
        super().__init__(parent)
        self.data = data

        entry2 = tk.Entry(self, textvariable=self.data.number2)
        entry2.pack()

        self.button2 = tk.Button(self, text="click", command=self.add2)
        self.button2.pack()

        self.frame2 = tk.LabelFrame(self, height=200, width=200, borderwidth=2)
        self.frame2.pack()

    def add2(self):
        self.frame2.config(text=str(self.data.number2.get()))

app = SampleApp()
app.mainloop()

uj5u.com熱心網友回復：

你可以這樣做：

import tkinter as tk


class Data:
    def __init__(self):
        self.number = tk.StringVar()


class SampleApp(tk.Tk):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.minsize(700, 700)
        container = tk.Frame(self)
        container.pack()

        self.data = Data()

        self.frames = {}
        for F in (PageOne,):
            frame = F(container, self.data)
            self.frames[F] = frame
            frame.grid(row=0, column=0, sticky="nsew")

    def show_frame(self, c):
        frame = self.frames[c]
        frame.tkraise()


class PageOne(tk.Frame):
    def __init__(self, parent, data):
        super().__init__(parent)
        self.data = data

        entry1 = tk.Entry(self, textvariable=self.data.number)
        entry1.pack()

        self.button1 = tk.Button(self, text="click", command=lambda : self.add(self.frame1, data.number))
        self.button1.pack()

        self.frame1 = tk.LabelFrame(self, height=200, width=200, borderwidth=2)
        self.frame1.pack()

        self.button2 = tk.Button(self, text="click", command=lambda : self.add(self.frame2, data.number))
        self.button2.pack()

        self.frame2 = tk.LabelFrame(self, height=200, width=200, borderwidth=2)
        self.frame2.pack()

    def add(self, frame, data):
        frame.config(text=str(self.data.number.get()))


app = SampleApp()
app.mainloop()
