EditorApplication.hierarchyWindowChanged

Description

A callback to be raised when an object in the hierarchy changes.

Each time an object is (or a group of objects are) created, renamed, parented, unparented or destroyed this callback is raised.

See Also: EditorWindow.OnHierarchyChange.

no example available in JavaScript

using UnityEditor;
using UnityEngine;

public class ExampleCode {
	[MenuItem ("Example/Hierarchy Window Changed")]
	static void Example () {
		EditorApplication.hierarchyWindowChanged += ExampleCallback;
	}
	static void ExampleCallback () {
		Object[] all = Resources.FindObjectsOfTypeAll (typeof (Object));
		Debug.Log ("There are " + all.Length + " objects at the moment.");
	}
}

Note: Changing the HideFlags on an object will also cause this callback to be called.
