# OnInteractivePreviewGUI(Rect, GUIStyle)

> Implement to create your own interactive custom preview. Interactive custom previews are used in the preview area of the inspector and the object selector.

## Definition

* **Type:** Method
* **Namespace:** [UnityEditor](/engine/6000.6/script-reference/unityeditor.md)
* **Assembly:** UnityEditor.CoreModule

```csharp
public virtual void OnInteractivePreviewGUI(Rect r, GUIStyle background)
```

### Parameters

**** (\[Rect]\(/engine/6000.6/script-reference/unityengine/rect)): Rectangle in which to draw the preview.**** (\[GUIStyle]\(/engine/6000.6/script-reference/unityengine/guistyle)): Background image.

### Remarks

Implement this method, instead of [Editor.OnPreviewGUI](/engine/6000.6/script-reference/unityeditor/editor/onpreviewgui.md), to display interactive custom previews. You can implement both methods when some previews are interactive and others are not. The overidden method should use the rectangle passed in and render a preview of the asset. The default implementation is a no-op.

**Note:** Inspector previews are limited to the primary editor of persistent objects (assets). For example, GameObjectInspector, MaterialEditor, TextureInspector, and so on. This means that it is currently not possible for a component to have its own inspector preview.

### Examples

```csharp
using UnityEngine;
using UnityEditor;

// Create an editor window which can display a chosen GameObject.
// Use OnInteractivePreviewGUI to display the GameObject and
// allow it to be interactive.

public class ExampleClass: EditorWindow
{
    GameObject gameObject;
    Editor gameObjectEditor;

    [MenuItem("Example/GameObject Editor")]
    static void ShowWindow()
    {
        GetWindowWithRect<ExampleClass>(new Rect(0, 0, 256, 256));
    }

    void OnGUI()
    {
        gameObject = (GameObject) EditorGUILayout.ObjectField(gameObject, typeof(GameObject), true);

        GUIStyle bgColor = new GUIStyle();
        bgColor.normal.background = EditorGUIUtility.whiteTexture;

        if (gameObject != null)
        {
            if (gameObjectEditor == null)
                gameObjectEditor = Editor.CreateEditor(gameObject);

            gameObjectEditor.OnInteractivePreviewGUI(GUILayoutUtility.GetRect(256, 256), bgColor);
        }
    }
}
```
