I want to add a hover effect over Notebook tabs. I used this method:
def hover(widget, on_entrance, on_exit, entrance_fg, exit_fg):
widget.bind("<Enter>", func=lambda e: widget.config(
bg=on_entrance, fg=entrance_fg))
widget.bind("<Leave>", func=lambda e: widget.config(
bg=on_exit, fg=exit_fg))
It is not showing any error, but it is not working.
