I’m trying to develop a very basic Tkinter drawing app, but cannot find a good event to use to detect mouse movement.

Binding <B1-Motion> works, but it does not count very small movements/the beginning of the stroke.
I have also considered swapping root.mainloop for root.update and including the function inside root.update’s while loop; example:

while True:
      if (mouse pressed):
         drawLine()
      root.update()

However, I have seen multiple people advise against the use of root.update in general.
Does anyone know if this is an appropriate use case or know of a better alternative(either to <B1-Motion> or Tkinter)?
