问题
Currently I am using this code:
from win10toast import ToastNotifier
toaster = ToastNotifier()
toaster.show_toast(
"Hello World!!!",
"Python is 10 seconds awesome!",
icon_path="",
duration=10
)
What I want to do is when the toast is clicked it could open a page in my browser. Prodecure like this:
- Notification comes
- I click it
- and it should open a website in my browser
回答1:
Change the init.py of win10 toast and see the magic
