Python：调用父类方法来取消配置窗口（Tkinter）会导致窗口中出现两组小部件

提问于

对于我的任何愚蠢或无知，我很抱歉，但我是Python的新手，也是一般的编码 . 我一直试图让一个用于游戏的用户界面我将要作为一种教我自己的方式python我有一个主窗口和一些按钮小部件 . Play游戏按钮打开第二个窗口（用于游戏本身）并使用.withdraw方法隐藏根窗口 . 这非常有效 . 在游戏窗口内我有另一个按钮，我想破坏游戏窗口并将用户带回我已撤回的根菜单窗口 . 这似乎有效，除非我每次调用它，它会在窗口中创建一组新的，重复的小部件，所以我最终得到了多个集合 .

我会在底部发布我的完整代码，但这里是我认为的相关部分 .

tkinter Button在父类（主窗口）内调用它 . 这很好用 .

def playGame(self):     #Start the main game window
    self.master.withdraw()
    gameWindow()

我在子类中使用bellow方法来破坏游戏窗口，然后在父类中调用一个方法来恢复先前的撤消窗口

def exitMenu(self):
    self.g.destroy()
    UI(root).showMenu()

这是有效的，除了它每次重复小部件导致这显示：

贝娄是我的全部代码，非常感谢你的帮助 .

import tkinter as tk
import PIL
from Config import *

root = tk.Tk()

class UI(): #Main Menu

    def __init__(self, master):

        #Create Main Menu Window

        self.master = master
        self.master.title("Monopoly")
        self.master.wm_iconbitmap('icons\Monopoly-Icon.ico')
        self.master.geometry((resolution))

        #Menu Buttons

        self.label = tk.Label(master, text= 'Welcome to Monopoly! PLACEHOLDER')
        self.playButton = tk.Button(master, text= 'Play Game', command= self.playGame)
        self.settingsButton = tk.Button(master, text= 'settings', command= self.settings)
        self.exitButton = tk.Button(master, text= 'Exit', command= self.exitGame)

        self.label.grid(columnspan=2)
        self.playButton.grid(column=0)
        self.settingsButton.grid(column=0)
        self.exitButton.grid(column=0)

    def settings(self):       #Opens Settings Window
        s = tk.Toplevel()
        s.title('Settings')
        s.wm_iconbitmap('icons\Monopoly-Icon.ico')
        s.geometry((resolution))
        self.master.withdraw()
        resLabel = tk.Label(s, text= 'Resolution')
        resOption = tk.OptionMenu(s, resolution, *resList)

        resLabel.grid(column=0,row=0)
        resOption.grid(column=0, row=4)

    def showMenu(self):     #Bring back menu windwow
        self.master.deiconify()

    def exitGame(self):    #Exit Game Method
        root.destroy()

    def playGame(self):     #Start the main game window
        self.master.withdraw()
        gameWindow()

class gameWindow(UI):

    def __init__(self):

        self.g = tk.Toplevel()
        self.g.title('Monopoly')
        self.g.wm_iconbitmap('icons\Monopoly-Icon.ico')
        self.g.geometry((resolution))

        self.menuButton = tk.Button(self.g, text= 'Main Menu', command= self.exitMenu)

        self.menuButton.grid(column=0,row=0)

    def exitMenu(self):
        self.g.destroy()
        UI(root).showMenu()

mainMenu = UI(root)

root.mainloop()

    您应该将父类 UI 传递给子类 gameWindow ，然后您可以在子类中使用父类的 showMenu() 方法 .

    从子窗口显示主窗口的代码将是： self.mainUI.showMenu() 而不是 UI(root).showMenu()

    儿童班成为：

    class gameWindow(UI):

    def __init__(self, mainUI): # Make the main window a parameter/attribute

        self.mainUI = mainUI # Make the main window a parameter/attribute
        self.g = tk.Toplevel()
        self.g.title('Monopoly')
        self.g.wm_iconbitmap('icons\Monopoly-Icon.ico')
        self.g.geometry((resolution))

        self.menuButton = tk.Button(self.g, text= 'Main Menu', command= self.exitMenu)

        self.menuButton.grid(column=0,row=0)

    def exitMenu(self):
        self.g.destroy()
        self.mainUI.showMenu()

    gameWindow 现在需要一个参数，因此您将主UI传递给 self

    def playGame(self):     #Start the main game window
        self.master.withdraw()
        gameWindow(self)

    这是完整的代码：

    import tkinter as tk
import PIL
from Config import *

root = tk.Tk()

class UI(): #Main Menu

    def __init__(self, master):

        #Create Main Menu Window

        self.master = master
        self.master.title("Monopoly")
        self.master.wm_iconbitmap('icons\Monopoly-Icon.ico')
        self.master.geometry((resolution))

        #Menu Buttons

        self.label = tk.Label(master, text= 'Welcome to Monopoly! PLACEHOLDER')
        self.playButton = tk.Button(master, text= 'Play Game', command= self.playGame)
        self.settingsButton = tk.Button(master, text= 'settings', command= self.settings)
        self.exitButton = tk.Button(master, text= 'Exit', command= self.exitGame)

        self.label.grid(columnspan=2)
        self.playButton.grid(column=0)
        self.settingsButton.grid(column=0)
        self.exitButton.grid(column=0)

    def settings(self):       #Opens Settings Window
        s = tk.Toplevel()
        s.title('Settings')
        s.wm_iconbitmap('icons\Monopoly-Icon.ico')
        s.geometry((resolution))
        self.master.withdraw()
        resLabel = tk.Label(s, text= 'Resolution')
        resOption = tk.OptionMenu(s, resolution, *resList)

        resLabel.grid(column=0,row=0)
        resOption.grid(column=0, row=4)

    def showMenu(self):     #Bring back menu windwow
        self.master.deiconify()

    def exitGame(self):    #Exit Game Method
        root.destroy()

    def playGame(self):     #Start the main game window
        self.master.withdraw()
        gameWindow(self)

class gameWindow(UI):

    def __init__(self, mainUI): # Make the main window a parameter/attribute

        self.g.title('Monopoly')
        self.g.wm_iconbitmap('icons\Monopoly-Icon.ico')
        self.g.geometry((resolution))

        self.menuButton = tk.Button(self.g, text= 'Main Menu', command= self.exitMenu)

        self.menuButton.grid(column=0,row=0)

    def exitMenu(self):
        self.g.destroy()
        self.mainUI.showMenu()

mainMenu = UI(root)

root.mainloop()
