How to call an objects custom inspector into a window?

Hiya folks,

So, let me see if i can cut this short.

I have a class which I used a custom inspector for. It is ripped(i.e. less code shown)
Assume proper namespacing is used and the following work.

TLDR: I need some way to inserting a custom inspector into my window when selecting an item(which is cached). How can I do this? Below scripts, I want a fill in for "DrawCustomInpsector" spot below.

Code (CSharp):

1. [System.Serializable]
2. public class BaseItem : ScriptableObject
3. {
4.     public string name;
5.         public int cost;
6. }

and custom editor below

Code (CSharp):

1. [CustomEditor(typeof(BaseItem))]
2. [CanEditMultipleObjects]
3. public class EditorBaseItem : Editor
4. {
5.     public override void OnInspectorGUI ()
6.     {
7.          BaseItem item = (BaseItem)this.target;
8.          EditorGUILayout.TextField ("Item name<custom>:", item.name);
9.      
10.          // Opens up the window with the asset info
11.          if(GUILayout.Button("Modify"))
12.          {                      
13.              CreateItemWindow.ShowWindowWithProperties(item);
14.          }
15.     }
16. }
17.  

Now standard custom window script

Code (CSharp):

1. [MenuItem("Window/Item Database Management")]
2. public static void ShowWindow()
3. {
4.     EditorWindow.GetWindow<BaseItemDatabaseWindow>();
5.  
6.     void OnGUI()
7.     {
8.         // SO, I have a scroll view on the left hand side. This contains my list of items.
9.         _item_selection_scroll_pos = GUI.BeginScrollView(new Rect(0f, 0f, position.width/3.5f, position.height), _item_selection_scroll_pos, new Rect(0f, 0f, position.width/4f, position.height*2));
10.        // Now, what I would like is when I select an item from the list. On the right hand side, the custom script appears.  
11.         int i = 0;
12.         foreach(BaseItem item in BaseItemDataBaseInstance.instance.main_data.data)
13.         {
14.             if(GUI.Button(new Rect(0, _height_offset * i++, position.width/3.5f, 20f), item.name))
15.             {
16.                // Store select item some how
17.                // _current_item = new SerializedObject(item);
18.                //_item = item;
19.             }
20.         }
21.  
22.         Rect right_side = new Rect(position.width/3.5f, 0.0f, position.width - position.width/3.5f, position.height);
23.         GUI.BeginGroup(right_side);
24.         if(/* we have the selected item */)
25.         {
26.             //DrawCustomInpsector<EditorBaseItem>(item)  // I wish....
27.         }
28.        GUI.EndGroup();
29.  
30.        this.Repaint();      
31.  

 

I figured it out with help from http://stackoverflow.com/questions/16054955/unity-custom-inspector-on-custom-window

This is what I was looking for...

Code (CSharp):

1.  
2. Editor editor = Editor.CreateEditor(_item);
3. editor.OnInspectorGUI();
4.  

I saw it, but was missing the part where I had to call that editors draw method.
