使用按钮通过tkinter GUI循环Python循环字典项

Question

我正在为我的餐厅做菜单测试.我已经制作了GUI并且对它的基本格式感到满意(现在),但我仍然坚持如何进行下一步.

我设置了多个复选框(不同的成分),并且计划是针对不同的菜单项循环(显示在屏幕上),然后员工检查相应的成分,单击我提交的提交和继续按钮,然后是下一个菜单项显示代替上一个.我需要做更多的事情,比如阅读和存储输入,但是现在我想在我继续前进之前跳过这个障碍.

我是使用Python进行GUI的新手,所以我不确定最好的方法.

我找到了不同的代码示例,但没有具体的东西可以实现到我的程序中.任何建议都非常感谢!!

这是我的GUI图片:

from tkinter import *

globalvar = -1

class Example(Frame):

    def __init__(self, parent):
        Frame.__init__(self, parent, background="white")   
        self.parent = parent
        self.initUI()

    def initUI(self):
        self.parent.title("Wahoos Menu Test")

def main():
    def callBack(number):
        globalvar = number + 1
        item(globalvar)
    def item(number):
        menu = ['nft', 'nckt']

那么，到底是什么问题呢？标题提到了循环字典。Tkinter 与任何其他库没有什么不同 - 您可以像处理其他任何事情一样进行循环。

例如：

for thing in ("Lettuce", "Cabbage", "Cheese"):
    var[thing] = IntVar()
    cb[thing] = Checkbutton(root, text=thing, variable=var[thing], ...)
    cb[thing].grid(...)
