Question

试图在tkinter中更改字体。按钮一直工作到我到达第七位我的猜测是Serif女士是两个字，通常我会在两个字前加上“” 但是我写程序的方式不对。

我的问题是如何修复我的函数以接受字体两个单词的名字。

以下是输出：

Counter:  1  Fontz:  Terminal 12 bold
Counter:  2  Fontz:  Fixedsys 12 bold
Counter:  3  Fontz:  Modern 12 bold
Counter:  4  Fontz:  Roman 12 bold
Counter:  5  Fontz:  Script 12 bold
Counter:  6  Fontz:  Courier 12 bold
Counter:  7  Fontz:  MS Serif 12 bold

代码：

from tkinter import font

import os

import random
import tkinter as tk

# Give 10 blank lines
print("\n"*10)

# Create path to GURPS gif files
home = os.path.expanduser('~')
dt = desktop = os.path.join(home,'Desktop')

    f_counter +=1
    fontz = str(ff[f_counter]) + " 12 bold"

    logo = tk.Label(root, compound = tk.CENTER, text = "GURPS\n CHARACTER\n SHEET", font=fontz, fg ="white", image=ggpi).grid(row=0, column=0)

root = tk.Tk()
ggpi =gurps_gif_photo_image = tk.PhotoImage(file=lip)

# List of all tkinter fonts
tk_fonts = font.families()
for font in tk_fonts:
    ff.append(font)
print(ff)
button_font()
logo = tk.Label(root, compound = tk.CENTER, text = "GURPS\n CHARACTER\n SHEET", font=fontz, fg ="white", image=ggpi).grid(row=0, column=0)
Label1 = tk.Label(root, text="Name: ", font ="bold").grid(row=0, column = 1)
button = tk.Button(root, text="Font Changer", command=button_font).grid(row=3,column=3)
root.mainloop()

Answer 1

使用元组而不是字符串-当名称具有多个空格时，tkinter不会将名称与大小混淆：

这有效：

fontz = (str(ff[f_counter]), 12, "bold")
logo = tk.Label(root, compound=tk.CENTER, 
    text="GURPS\n CHARACTER\n SHEET",
    font=fontz,
    fg ="white", 
    image=ggpi
).grid(row=0, column=0)

_tkinter.TclError：预期的整数，但得到“ Serif”
