Tkinter小部件都包裝在同一框架中

Question

我試圖用多個窗口制作一個相當簡單的GUI。 我現在將我的窗口構建為類，現在每個窗口中都帶有一個標簽。 我似乎無法弄清楚為什么當我運行程序時，它將所有標簽都包裝在“ StartPage”上，而其他所有窗口中都沒有。 可能是我的班級配置不正確？

import tkinter as tk


class application(tk.Tk):

def __init__(self, *args, **kwargs):
    tk.Tk.__init__(self, *args, **kwargs)
    container = tk.Frame(self)
    container.pack(side = 'top', fill = 'both', expand = True)

    container.grid_rowconfigure(0, weight = 1)
    container.grid_columnconfigure(0, weight = 1)

    self.frames = {}

    for F in (StartPage, WeeklyBudget, LongtermSavings, Investments):
        frame = F(container, self)
        self.frames[F] = frame

        frame.grid(row=0, column=0, sticky="nsew")


    self.ShowFrame(StartPage)

def ShowFrame(self, cont):
    frame = self.frames[cont]
    frame.tkraise()


class StartPage(tk.Frame):
    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        start_label = tk.Label(self, text = 'Welcome to Finance Track!')
        start_label.pack()
        week_btn = tk.Button(self, text = 'Weekly Budgeting', command =lambda: controller.ShowFrame(WeeklyBudget))
    savings_btn = tk.Button(self, text = 'Longterm Savings', command = lambda: controller.ShowFrame(LongtermSavings))
    invest_btn = tk.Button(self, text = 'Investments', command = lambda: controller.ShowFrame(Investments))


    week_btn.pack(pady = 10, padx = 10)
    savings_btn.pack(pady = 10, padx = 10)
    invest_btn.pack(pady = 10, padx = 10)

class WeeklyBudget(tk.Frame):
    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        label = tk.Label(text = 'Welcome to your Weekly Budget')
        label.pack()
        add_btn = tk.Button(text = 'add new week')
        add_btn.pack()

class LongtermSavings(tk.Frame):
    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        label = tk.Label(text = 'Welcome to your Longterm Savings')

        label.pack()

class Investments(tk.Frame):
    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        label = tk.Label(text = 'Welcome to your Investments')
        label.pack()

app = application()
app.mainloop()

如前所述，當前的結果只是一個窗口，其中包含所有標簽和所有按鈕。

正如jasonharper所提到的，您並沒有定義許多小部件的父級（也就是母版）。

class Investments(tk.Frame):
    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        label = tk.Label(text = 'Welcome to your Investments')
        label.pack()

例如，使用此Investments類，默認情況下，標簽將被賦予窗口作為父窗口，將其父窗口設置為新創建的框架，只需執行以下操作：

class Investments(tk.Frame):
    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        label = tk.Label(self, text = 'Welcome to your Investments')
        label.pack()
