使按钮消失在Tkinter

问题描述：

我在做一个在学校的编码项目，我试图为我的按钮设置功能，但是当我运行代码时按钮运行的命令没有被点击，他们不消失因为按钮隐藏的功能提到他们不工作：使按钮消失在Tkinter

from tkinter import * 
import tkinter 
#Parent Window Setup 
GoodChefWindow = Tk() 
GoodChefWindow.title("Welcome To GoodChef") 
GoodChefWindow.geometry("600x500") 

#Displaying Company Logo 
Logo=PhotoImage(file="LogoV2.gif") 
LogoCanvas=tkinter.Canvas(GoodChefWindow,height=150, width=600) 
LogoCanvas.create_image(300,75,image=Logo) 
LogoCanvas.pack() 

#Pickup and Delivery buttons 
def Delivery_Clicked(): 
    Delivery=Tk() 
    Delivery.title("Delivery Options") 
    Delivery.geometry("400x333") 
    Remove_Buttons() 

def PickUp_Clicked(): 
    Delivery=Tk() 
    Delivery.title("Pick Up Options") 
    Delivery.geometry("400x333") 
    Remove_Buttons() 

def Remove_Buttons(): 
    MenuButtonsFrame.destroy() 

def Buttons(MenuButtonsFrame):  
    DeliveryIcon=PhotoImage(file="Delivery_Icon.gif") 
    PickUpIcon=PhotoImage(file="Pick_Up_Icon.gif") 
    MenuButtonsFrame = LabelFrame(GoodChefWindow, text="Order") 
    MenuButtonsFrame.pack() 
    DeliveryLabelFrame = LabelFrame(MenuButtonsFrame) 
    DeliveryLabelFrame.pack(side=RIGHT,expand="yes") 
    PickUpLabelFrame = LabelFrame(MenuButtonsFrame) 
    PickUpLabelFrame.pack(side=LEFT,expand="yes") 
    DeliveryButton = tkinter.Button(DeliveryLabelFrame,bg="red", 
            fg="yellow",compound="left", 
            image=DeliveryIcon,height=40, 
            width=120,text="Delivery", 
            command=Delivery_Clicked()) 
    PickUpButton = tkinter.Button(PickUpLabelFrame,bg="red", 
            fg="yellow",compound="left", 
            image=PickUpIcon,height=40, 
            width=120,text="Pick Up", 
            command=PickUp_Clicked()) 
    DeliveryButton.pack() 
    PickUpButton.pack() 

Buttons()

此代码不运行（在调用'Buttons'时缺少参数）。请发布您正在运行的实际代码。此外，遵守[Python命名指南]（http://legacy.python.org/dev/peps/pep-0008/）会很好。 – BartoszKP 2014-09-28 11:21:24

您的代码正在做一些根本性错误的操作，这可能会导致多种类型的不良副作用。你不应该创建超过一个'Tk'的实例。如果你需要多个窗口，你需要创建'Toplevel'实例。 – 2014-09-28 12:57:30

你真的需要重新思考你的方法在我看来，这里是我会做你有什么迄今方式：

from tkinter import * 

#Parent Window Setup 
GoodChefWindow = Tk() 
GoodChefWindow.title("Welcome To GoodChef") 
GoodChefWindow.geometry("600x500") 

#Displaying Company Logo 
Logo=PhotoImage(file="rd.gif") 
LogoCanvas=Canvas(GoodChefWindow,height=150, width=600) 
LogoCanvas.create_image(300,75,image=Logo) 
LogoCanvas.pack() 

#Pickup and Delivery buttons 
def Delivery_Clicked(): 
    Delivery=Toplevel() 
    Delivery.title("Delivery Options") 
    Delivery.geometry("400x333") 
    Remove_Buttons(MenuButtonsFrame) 

def PickUp_Clicked(): 
    Delivery=Toplevel() 
    Delivery.title("Pick Up Options") 
    Delivery.geometry("400x333") 
    Remove_Buttons(MenuButtonsFrame) 

def Remove_Buttons(MenuButtonsFrame): 
    MenuButtonsFrame.destroy() 

DeliveryIcon=PhotoImage(file="rd.gif") 
PickUpIcon=PhotoImage(file="rd.gif") 
MenuButtonsFrame = LabelFrame(GoodChefWindow, text="Order") 
MenuButtonsFrame.pack() 
DeliveryLabelFrame = LabelFrame(MenuButtonsFrame) 
DeliveryLabelFrame.pack(side=RIGHT,expand="yes") 
PickUpLabelFrame = LabelFrame(MenuButtonsFrame) 
PickUpLabelFrame.pack(side=LEFT,expand="yes") 
DeliveryButton = Button(DeliveryLabelFrame,bg="red", 
           fg="yellow",compound="left", 
           image=DeliveryIcon,height=40, 
           width=120,text="Delivery", 
           command=Delivery_Clicked) 
PickUpButton = Button(PickUpLabelFrame,bg="red", 
           fg="yellow",compound="left", 
           image=PickUpIcon,height=40, 
           width=120,text="Pick Up", 
           command=PickUp_Clicked) 
DeliveryButton.pack() 
PickUpButton.pack() 

mainloop()

这应该有帮助吗？如果不说出来！你也可以做更多的tk窗口（顶层是没有必要的）。
