Tkinter cho phép đổi màu con trỏ chuột (cursor) cho widget. Cú pháp: cursor="cursor_type color".
Ví dụ: cursor="plus red" - con trỏ hình dấu cộng màu đỏ. cursor="dot blue" - chấm màu xanh.
Ví dụ
from tkinter import *
win = Tk()
win.geometry("700x350")
Label(win, text="label cursor", cursor="plus red", font=('calibri 18')).pack(pady=20)
Button(win, text="Button cursor", cursor="dot blue").pack()
win.mainloop()
Kết quả
Hover vào Label → con trỏ thành dấu cộng đỏ. Hover Button → chấm xanh.
