标签“bg"不存在 [英] Label `bg` does not exist

问题描述

这是我的标签代码

from Tkinter import Tk, BOTH, Canvas, Text,END
import Tkinter as tk
from ttk import Frame, Button, Style, Label, Entry
from tkMessageBox import *
from random import *


class Life(Frame): #is indented correctly in my code
def __init__(self, parent):
    Frame.__init__(self, parent)
    self.parent = parent
    self.initUI()

def initUI(self):
    self.parent.title('MTG LIFE COUNTER')
    self.style = Style()
    self.style.theme_use('default')
    self.pack(fill=BOTH, expand=1)

    can = Canvas(self, width=800, height=500, borderwidth=5, background='black')
    can.pack()

    can.create_rectangle(0, 0, 200, 200, fill="white", outline="white")

    self.add = Button(self, text="Add 1", command=self.rollDice)
    self.add.place(x=20, y=210)

    self.sub = Button(self, text="Subtract 1", command=self.rollDice)
    self.sub.place(x=20, y=230)

    self.diceRoll = Button(self, text="Dice!", command=self.rollDice)
    self.diceRoll.place(x=20, y=250)

    self.coin = Button(self, text="Coin", command=self.rollDice)
    self.coin.place(x=20, y=270)

    color = 'yellow'
    l = Label(self, textvariable=color)
    self.namet = Label(self, text="What's your name?", bg='black')
    self.namet.place(x=215, y=10)


    self.v = tk.StringVar()
    self.nameBox = Text(self, height=1, width=10)
    self.nameBox.place(x=215,y=30)

我得到的错误是...

File ".\Mtg Life Counter.py", line 64, in <module>
main()
File ".\Mtg Life Counter.py", line 60, in main
app = Life(root)

我的问题是如何更改标签的背景和前景?

My question is how do I change the background and foreground of a label?

我在没有 -fg 和 -bg 选项的情况下尝试过，代码工作得很好.尝试寻找正确的语法都说就是这样.所有帮助将不胜感激.

I tried without the -fg and -bg options the code works just fine. Tried looking for the correct syntax all say that this is it. All help would be appreciated.

推荐答案

问题是你使用的是 ttk Label 小部件，它不支持 bg或 ft 选项.您可以使用 background 和 foreground 代替.

The problem is that you are using the ttk Label widget, and it does not support the bg or ft options. You can use background and foreground instead.
