Question Do we have events for +/- buttons for serialized list?

Hi guys.

I just want to ask if Unity has any events when the user clicks these buttons? If not - maybe anybody knows the way how to hook up these actions?

 

Could do it like this..

Code (CSharp):

1.  
2. using System.Collections.Generic;
3. using UnityEngine;
4. public class TestListChangeEvent : MonoBehaviour
5. {
6.   private int previousCount = 0;
7.   public List<int> ints = new List<int>();
8.   private void OnValidate()
9.   {
10.     if (ints.Count != previousCount)
11.     {
12.       Debug.Log("change detected: " + ((ints.Count > previousCount) ? "more" : "less") + " items now.");
13.       previousCount = ints.Count;
14.     }
15.   }
16. }

Edit: To avoid an initial event, could serialize previousCount, or default that to -1, and in OnValidate if it's -1 just set it to the current count and return instead of checking.
