Intractable CustomPropertyDrawer

Hi ( This is a UnityEditor question )

I am using CustomPropertyDrawer and need access to the class being drawn.

I use Reflection to get the instance from serializedObject's targetObject.

 TestProperty testProperty = (TestProperty)fieldInfo.GetValue (property.serializedObject.targetObject);

Problem :

It doesn't work when it is a field within another serialized class, nor does it work in an array. This is because the serializedObject's targetObject is always the MonoBehaviour.

Question :

How do I get access to the instance of what the PropertyDrawer is drawing ?

Let's replicate the core of my code :

(1) Here is the class we'll be using for testing :

 [System.Serializable]public class TestProperty{}

(2) For now, we'll displaying the type of the serialized property :

 [CustomPropertyDrawer (typeof(TestProperty), true)]
 public class CustomPropertyDrawer_PropertyField : PropertyDrawer
 {
     public override void OnGUI (Rect position, SerializedProperty property, GUIContent label)
     {
         position = EditorGUI.PrefixLabel (position, GUIUtility.GetControlID (FocusType.Passive), label);
         // Display something useful
         string labelValue = property.type.ToString ();
         EditorGUI.LabelField (position, labelValue, EditorStyles.label);
     }
 }

(3) And then to test it, we place this in some random MonoBehaviour

 public TestProperty testField;
 public TestProperty[] testFieldArray = new TestProperty[3];
