How to detect on which part of screen (left or right) is an event in React big calendar?

Question

I want to create a tooltip, but it overflows if the event located on the right side, so i need to detect an event position somehow.

Answer 1

Inside the event object you can find different properties like screenX, screenY, pageX, pageY, clientX and clientY etc which can give you mouse position relative to screen, page and client.
