Adding mouse over event to toggle

How can I add an event to watch for mouse hover over a toggle button in unity 5?

 

You add an Event Triggers component then add PointerEnter event:

 

My GUI items are being added through code though

 

Try this

Code (CSharp):

1.    using UnityEngine.EventSystems;
2.    ...
3.     void AssignEvent(){
4.         EventTrigger eventTrigger = _targetButton.gameObject.AddComponent<EventTrigger>();
5.         EventTrigger.Entry eventEntry = new EventTrigger.Entry();
6.         eventEntry.eventID = EventTriggerType.PointerEnter;
7.         eventEntry.callback.AddListener((data) => {OnPointerEnterDelegate((PointerEventData)data); });
8.         eventTrigger.triggers.Add(eventEntry);
9.     }
10.  
11.     public void OnPointerEnterDelegate(PointerEventData data)
12.     {
13.         //Take some action here
14.     }

 

my target button is actually made from script, GUI.Toggle(new Rect(20,(70*i) + 70, 100,50), items, names);
