hover 在 tkinter 中的按钮颜色上

Question

我正在处理这个 tkinter 项目，我即将完成，但是当我使用 hover 时，我似乎无法找到更改按钮颜色的方法，所以你能帮忙这里是我的代码

import tkinter as tk

window = tk.Tk()
img = tk.PhotoImage(file='C:\\Users\\laithmaree\\PycharmProjects\\create_apps_with_python\\brainicon.ico.png')
window.title("Quiz Game")

# i created an icon
# i made a title


window.geometry("800x600")
window.resizable(width=False, height=False)
window.iconphoto(False, img)

label1 = tk.Label(window, text='Quiz App', font=("Arial Bold", 25))
label1.pack()

txtbox = tk.Entry(window, width=50)


def playbuttonclicked():
    label1.destroy()
    playbtn.destroy()
    quitbtn.destroy()
    label2 = tk.Label(window, text='What is the short form of computer science', font=("Arial Bold", 25))
    label2.pack()
    txtbox.place(x=250, y=200, height=40)

    def chkanswer():
        useranswer = txtbox.get()  # Get contents from Entry
        if useranswer == 'cs':
            lblcorrect = tk.Label(window, text='correct')
            lblcorrect.pack()

            def delete():
                lblcorrect.destroy()

            lblcorrect.after(1000, delete)


        else:
            lblwrong = tk.Label(window, text='Try Again')
            lblwrong.pack()

            def deletefunction():
                lblwrong.destroy()

            lblwrong.after(1000, deletefunction)

    submitbtn = tk.Button(window, text='Submit', font=('Arial Bold', 30), command=chkanswer, bg='red')
    submitbtn.place(x=305, y=400)


playbtn = tk.Button(window, text='Play', font=("Arial Bold", 90), bg='red', command=playbuttonclicked)
playbtn.place(x=10, y=200)


def quitbuttonclicked():
    window.destroy()


quitbtn = tk.Button(window, text='Quit', font=("Arial Bold", 90), bg='red', command=quitbuttonclicked)
quitbtn.place(x=400, y=200)

window.mainloop()

按钮是 submitbtn，playbtn，quitbtn 我希望按钮上的 hover 是黑色的，那里已经是红色了

将每个按钮绑定到进入和离开事件（当鼠标进入和离开小部件时）并根据触发的事件更改按钮的背景颜色：

btn.bind('<Enter>', lambda e: e.widget.config(bg='black'))
btn.bind('<Leave>', lambda e: e.widget.config(bg='red'))
