Question Reorderable List is never selecter or focused

Hi all,

I've a custom Editor where I use a Reorderable List. Its elements are never focused or selecter neither I use custom method neither default ones.

Can you help me?

Here is the code.

Code (CSharp):

1.  
2.         ReorderableList _reorderableStartingElements;
3.  
4. public override void OnInspectorGUI()
5.         {          
6.             GUIStyle HeaderBackground = new GUIStyle("RL Header");
7.  
8.             Rect position = EditorGUILayout.GetControlRect(false, 7.5f);
9.             position.height = EditorGUIUtility.singleLineHeight;
10.  
11.             _reorderableStartingElements = new ReorderableList(serializedObject, serializedObject.FindProperty("_startingElements"), true, true, true, true)
12.            {
13.                 drawElementBackgroundCallback = DrawListElementBackground,
14.                 elementHeight = 19,
15.                 elementHeightCallback = CalculateCallHeight
16.             };
17.  
18.                 _reorderableStartingElements.DoLayoutList();
19.  
20.             serializedObject.ApplyModifiedProperties();
21.         }
22.        
23. private float CalculateCallHeight(int index)
24.         {
25.             return EditorGUI.GetPropertyHeight(_reorderableStartingElements.serializedProperty.GetArrayElementAtIndex(index));
26.         }
27.  
28.         public void DrawListElementBackground(Rect rect, int index, bool selected, bool focused)
29.         {
30.             if (Event.current.type != EventType.Repaint)
31.                 return;
32.  
33.             GUIStyle HeaderBackground = new GUIStyle("RL Header");
34.  
35.             Color[] pix = new Color[Mathf.FloorToInt(rect.width * rect.height)];
36.            
37.             for (int i = 0; i < pix.Length; i++)
38.                 pix[i] = selected || focused ? Color.blue : index % 2 == 0 ? Color.cyan : Color.yellow;
39.            
40.             Texture2D result = new Texture2D((int)rect.width, (int)5);
41.             result.SetPixels(pix);
42.             result.Apply();
43.            
44.             HeaderBackground.normal.background = result;
45.             EditorGUI.LabelField(rect, "", HeaderBackground);
46.  
47.             //ReorderableList.defaultBehaviours.elementBackground.Draw(rect, false, selected, selected, focused);
48.         }
49.  

"_startingElements" is a simple List<int>. I let the comment where I use the default ReorderableList Draw method withous succeed.

Thank you in advance.

P.s.
Code is not optimized, I'm trying to make work it before.
