Question

我正在尝试创建一个从列表生成按钮的系统，然后按下每个按钮时该按钮消失并更新按钮按下的顺序创建的列表中的值，即[ 1,3,2,4]意味着先按下第一个按钮，然后按下第3个，第2个按钮等。

我现在已经在按钮消失但我还不能增加订单或生成列表的阶段。

def buttonSelected(k, buttonNames, order, itemButton, buttonOrder):
    order = order + 1
    itemButton[k].destroy()
    buttonOrder[k] = order

    orderText = ["first, second, third"]
    if order <= 2:
        lbl.configure(text="Which button do you want to click first?")
    else:
        lbl.configure(text="Which button do you want to click %sth?" % order)
    return order

def chooseOrder(buttonNames, order, buttonOrder):
    orderText = ["first, second, third"]
    itemButton = []

    for i in range(len(buttonNames)):
        print i
        itemButton.append('')
        itemButton[i] = tkinter.Button(window, text=buttonNames[i], command=lambda c=i: buttonSelected(c, buttonNames, order, itemButton, buttonOrder), font=("Helvetica", 10))
        itemButton[i].pack()

    if order <= 2:
        lbl.configure(text="Which button do you want to click first?")
    else:
        lbl.configure(text="Which button do you want to click %sth?" % order)

buttonOrder = []
for i in range(len(buttonNames)):
        buttonOrder.append(0)

chooseOrder(buttonNames, 0, buttonOrder)

我的订单没有迭代，因为我没有返回它，我也不知道如何返回列表。

这是我的完整代码：

# import and rename the 'tkinter' module for < Python 3.3
import Tkinter as tkinter
import os

class Checkbar(tkinter.Frame):
    def __init__(self, parent=None, picks=[], side=tkinter.TOP, anchor=tkinter.W):
        tkinter.Frame.__init__(self, parent)
        self.vars = []
        for pick in picks:
            var = tkinter.IntVar()
            chk = tkinter.Checkbutton(self, text=pick, variable=var, font=("Helvetica", 10))
            chk.pack(side=side, anchor=anchor, expand=tkinter.YES)
            self.vars.append(var)

    if order <= 2:

Answer 1

RESULT = []

def moduleSelected(k, wantedModules, order, itemButton, moduleOrder):
    order = order + 1
    #for j in range(len(itemButton)):
    itemButton[k].destroy()
    moduleOrder[k] = order
    print k
    RESULT.append(k+1)
    print RESULT # -> This will print the output you want.
    #chooseOrder(wantedModules, order)
    orderText = ["first, second, third"]
    if order <= 2:
        lbl.configure(text="Which item do you want appearing first?")
    else:
        lbl.configure(text="Which item do you want appearing %sth?" % order)
    if order == len(moduleOrder):
        moduleOrder1Finished = 1
    return order

我添加了一个RESULT列表来存储点击它们的按钮的顺序。

Tkinter按下按钮以生成列表
