Editor.OnPreviewGUI

参数

描述

Creates a custom preview for the preview area of the Inspector, the headers of the primary Editor, and the object selector.

You must implement Editor.HasPreviewGUI for this method to be called.

如果实现 OnInteractivePreviewGUI，将仅针对非交互式自定义预览调用此方法。 重写方法应在指定矩形 (r) 中渲染资源预览。 默认实现为无操作。

Note: Inspector previews are limited to the primary Editor of persistent objects, such as GameObjectInspector, MaterialEditor, and TextureInspector. A component cannot have its own Inspector preview.

using UnityEngine;
using UnityEditor;

[CreateAssetMenu]
class MyObject : ScriptableObject
{
    public string text;
}

// Show a preview of the text saved in MyObject.
[CustomEditor(typeof(MyObject))]
public class MyObjectEditor : Editor
{
    public override bool HasPreviewGUI() => true;

    public override void OnPreviewGUI(Rect r, GUIStyle background)
    {
        GUI.Label(r, (target as MyObject).text);
    }
}
