tkinter 按钮文字颜色不变

Question

按钮文本颜色在创建时为蓝色，一旦单击，按钮文本颜色应根据代码变为红色。 但是点击颜色并没有改变

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()

Answer 1

您需要从on_click function 中删除state=DISABLED才能使这项工作

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