Python Tkinter按钮参数

我最近开始学习python。我在图形用户界面方面没有什么经验，希望能学到更多。通过很少的研究，我发现tkinter可以让它成为现实。作为一个项目，决定让游戏策划者

我正在做的是用OptionMenu和可用的颜色放置一些行。在右边我放置了一个确认按钮，它设置了命令“validate”。问题是，我想用下面的代码向每个按钮（帧和行）传递不同的值，问题是它说行总是9

我想了一个可能的解决方案，那就是在y=0结束时复位，每次按下按钮加1。但我认为应该更简单一些

from tkinter import *

def selectedColor(var):
    print("Value is: " + var)

def validate(frame, row):
    # pass
    print("Frame: " + str(frame) + " row: " + str(row))
    rowToValidate = frame.nametowidget("." + str(row))
    for x in range(0,4):
        columnValue = frame.nametowidget("." + str(x) + str(row))
        print(columnValue)

master = Tk()

OPTIONS

 = [
    "RED",
    "BLUE",
    "YELLOW",
    "VIOLET",
    "ORANGE",
    "GREEN",
    "BROWN",
    "WHITE",
    "BLACK"
]

colorQuantity = 4
tries = 10
for y in range(0, tries):
    frame = Frame(master, name=str(y))
    isEnabled = "disabled" if y != 0 else "normal"
    for x in range(0,colorQuantity):
        variable = StringVar(frame, name=str(x)+str(y))
        variable.set("Choose color") # default value
        # print(str(variable))

        w = OptionMenu(frame, variable, *OPTIONS, command=selectedColor)        
        w.configure(state=isEnabled)
        w.pack(side=LEFT)
    confirmButton = Button(frame, text="Confirm", command= lambda: validate(frame, y+1))
    confirmButton.configure()
    confirmButton.pack(side=TOP)
    print(str(frame))
    frame.pack(side=TOP)


master.mainloop()

我会将OptionMenu变量保存在一个列表中，以便于检索它们的值。通过在命令选项中使用

partial

（），可以确保每一行都获得正确的行号作为输入

请参阅下面的代码（我还在下拉列表中添加了一些格式）：

由于for循环中的

lambda

，出现问题（请参阅和）

from tkinter import *
from functools import partial

def selectedColor(var):
    print("Value is: " + var)

def validate(args):
    frame = args[0]
    row = args[1]

    for x in range(0,4):
        print(rows[row][x].get())

master = Tk()

OPTIONS = [
    "RED",
    "BLUE",
    "YELLOW",
    "VIOLET",
    "ORANGE",
    "GREEN",
    "BROWN",
    "WHITE",
    "BLACK"
]

colorQuantity = 4
tries = 10
rows =[]
for y in range(0, tries):
    frame = Frame(master, name=str(y))
    isEnabled = "disabled" if y != 0 else "normal"
    row = []
    for x in range(0,colorQuantity):
        variable = StringVar(frame, name=str(x)+str(y))
        variable.set("Choose color") # default value
        # print(str(variable))
        row.append(variable)

        w = OptionMenu(frame, variable, *OPTIONS, command=selectedColor)  
        w.configure(width=len("Choose color"))      
        w.configure(state=isEnabled)
        w.pack(side=LEFT)
    rows.append(row)
    confirmButton = Button(frame, text="Confirm", command=partial(validate,(frame, y)))
    confirmButton.configure()
    confirmButton.pack(side=TOP)
    print(str(frame))
    frame.pack(side=TOP)


master.mainloop()
