> Override this method to create your own Inpsector GUI for a ScriptedImporter.

## Definition

* **Type:** Method
* **Namespace:** [UnityEditor.AssetImporters](/engine/6000.0/script-reference/unityeditor/assetimporters.md)
* **Assembly:** UnityEditor

```csharp
public override void OnInspectorGUI()
```

### Remarks

For the OnInspectorGUI Undo/Redo and cancel feature to work in the Inspector, you must either call ApplyRevertGUI or override needsApplyRevert to return false.

Example of an InspectorGUI using ApplyRevertGUI:

```csharp
using UnityEditor;
using UnityEditor.AssetImporters;
using UnityEngine;

public class CustomInspector : ScriptedImporterEditor
{
    SerializedProperty myProperty;

    public override void OnEnable()
    {
        base.OnEnable();

        myProperty = serializedObject.FindProperty("m_MyProperty");
    }

    public override void OnInspectorGUI()
    {
        serializedObject.Update();

        EditorGUILayout.PropertyField(myProperty);

        serializedObject.ApplyModifiedProperties();

        ApplyRevertGUI();
    }
}
```

Example of an InspectorGUI where the user cannot change anything and does not require an ApplyRevertGUI:

```csharp
using UnityEditor;
using UnityEditor.AssetImporters;
using UnityEngine;

public class CustomInspector : ScriptedImporterEditor
{
    SerializedProperty myProperty;

    public override void OnEnable()
    {
        base.OnEnable();

        myProperty = serializedObject.FindProperty("m_MyProperty");
    }

    protected override bool needsApplyRevert => false;

    public override void OnInspectorGUI()
    {
        serializedObject.Update();

        EditorGUILayout.LabelField(myProperty.displayName, myProperty.stringValue);

        serializedObject.ApplyModifiedProperties();
    }
}
```
