tkinter按钮的文字颜色没有改变

问题描述

按钮文字颜色在创建时为蓝色，一旦单击，按钮文字颜色应根据代码更改为红色。但是点击后颜色不会改变

from tkinter import Button,Tk,Frame,disABLED,Label
def on_click(button_id):
      btn[button_id].configure(text='clicked',state=disABLED,fg ="red")

window = Tk()
frame = Frame(window)
frame2 = Frame(window)
frame2.pack()
frame.pack()
btn=[]
lbl=Label(frame2,text="Hello there")
lbl.pack()
for i in range(0,5):
    b=Button(frame,text="hello!!",fg="blue",font='sans 8 bold',command = lambda         
       button_id=i: on_click(button_id),width = 4,relief = "groove")
    b.grid(row=i,column=0)
    btn.append(b)

window.mainloop()

解决方法

您需要从 state=DISABLED 功能中删除 on_click 才能实现此功能

def on_click(button_id):
      btn[button_id].configure(text='clicked',fg ="red")
