Editor.HasPreviewGUI

Returns

bool @return True если компонент может быть предпросмотрен в текущем состоянии.

Description

Переопределите этот метод в подклассах, если вы реализуете OnPreviewGUI.

You can also use it to disable or enable preview depending on the target asset. The default implementation simply returns false, so if you override OnPreviewGUI you have to override this method as well.

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

using UnityEngine;
using UnityEditor;

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

    [MenuItem("Window/GameObject Editor")]
    static void ShowWindow()
    {
        GetWindow<GameObjectEditorWindow>("GameObject Editor");
    }

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

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

            gameObjectEditor.OnPreviewGUI(GUILayoutUtility.GetRect(500, 500), EditorStyles.whiteLabel);
        }
    }
}
