[英]The button text and color does not appear on Tkinter program
該程序在運行window或ubuntu的其他計算機上運行正常,但文本不會顯示在按鈕上。 這是一段較長代碼的片段:
from Tkinter import *
from math import atan
from math import log
import math
import matplotlib
matplotlib.use('TkAgg')
import matplotlib.pyplot as plt
# --- function ---
def create_first_frame():
global root
global frame
# frame.destroy()
frame = Frame(bg="blue")
frame.pack()
label1 = Label(frame, text="hello!", fg="white", bg="blue", font="normal 30")
label1.pack()
button1 = Button(frame, text="Enter", fg="white", bg="blue", font="normal 20")
button1.pack()
button2 = Button(frame, text="Exit", font="normal", fg="white", bg="red", command=root.destroy)
button2.pack(side=LEFT)
root = Tk()
create_first_frame()
root.mainloop()
我們期待像“開始”和“退出”這樣的詞語。
我們只希望按鈕的顏色與文本一起顯示
我不確定問題是什么。 我拿出了不必要的進口貨,跑了
from tkinter import *
def create_first_frame():
global root
global frame
# frame.destroy()
frame = Frame(bg="blue")
frame.pack()
label1 = Label(frame, text="hello!", fg="white", bg="blue", font="normal 30")
label1.pack()
button1 = Button(frame, text="Enter", fg="white", bg="blue", font="normal 20")
button1.pack()
button2 = Button(frame, text="Exit", font="normal", fg="white", bg="red", command=root.destroy)
button2.pack(side=LEFT)
root = Tk()
create_first_frame()
root.mainloop()
這為我創造了:
這是你指定的顏色......
