Question

我正在做一个投票系统试图在我的学校实施它。

所以程序应该是这样的：

尚未实施的功能会根据要投票的学生人数生成一些密码。
主窗口显示所有候选人。
当您点击该按钮时，会出现一个弹出窗口（顶级），提示您输入密码
如果密码正确，会弹出另一个窗口（另一个Toplevel，这就是问题），显示一些按钮，您只需点击选择候选人。
重复完成

        self.button11.pack(side = LEFT)
        self.button12 = Button(self.topFrame, text = "Proyecto 12", command = self.close(self.button12val))#(options, self.button12val))
        self.button12.pack(side = LEFT)

    def close(self, variable):

        variable +=1

        self.top.destroy()


def onClick():

    run = app(root)

    root.wait_window(run.top)


root = Tk()
root.configure(bg = "white")
mainButton = Button(root, text='Click aqui para votar', command=onClick)
mainButton.pack()
root.mainloop()

所以问题是最后一个顶层窗口出现在我的主窗口而不是显示在一个新的弹出窗口上，有一次我让它工作，选项没有正确显示。请帮忙。

您在optionsWindows（）中拼错了topframe。此外，你不会包装topf（F）rame，所以它不会出现。最后，为optionsWindows中的按钮传递一个变量to command =。

from Tkinter import *
import tkMessageBox
from functools import partial

class app(object):
        def __init__(self, parent):
                self.availableCodes = [1,2, 3, 4, 5]
                top = self.top = Toplevel(parent)
                self.label1 = Label(top, text = "Ingrese su contrasena")
                self.label1.pack()
                self.entry1 = Entry(top)
                self.entry1.pack()
                self.button1 = Button(top, text = "Ingrese", command = self.ok)
                self.button1.pack(pady= 5)

        def ok(self):
                self.code = int(self.entry1.get())
                self.voteWindow()
                self.top.destroy()

        def voteWindow(self):
                print "vote window"
                if self.code in self.availableCodes:
                        print "True"
                        self.optionsWindows(self.top)
                        self.availableCodes.remove(code)
                else:
                        print "False"

        def optionsWindows(self, parent):
                new = self.new = Toplevel(parent)
                self.topFrame = Frame(new)
                self.topFrame.pack()
                for num in range(12):
                    button = Button(self.topFrame, text = "Proyecto %s" % (num+1),
                             command = partial(self.close, num))
                    button.pack(side="left")

        def close(self, variable):
                variable +=1
                print variable, "passed to self.close()"
                self.top.destroy()


def onClick():

        run = app(root)

        root.wait_window(run.top)


root = Tk()
root.configure(bg = "white")
mainButton = Button(root, text='Click aqui para votar', command=onClick)
mainButton.pack()
Button(root, text="Exit", command=root.quit).pack(side="bottom")
