> Base class for toolbar elements intended to be drawn in an Overlay.

## Definition

* **Type:** Class
* **Namespace:** [UnityEditor.Overlays](/engine/6000.3/script-reference/unityeditor/overlays.md)
* **Assembly:** UnityEditor
* **Inherits from:** [VisualElement](/engine/6000.3/script-reference/unityengine/uielements/visualelement.md)
* **Implements:** [IEventHandler](/engine/6000.3/script-reference/unityengine/uielements/ieventhandler.md), [IResolvedStyle](/engine/6000.3/script-reference/unityengine/uielements/iresolvedstyle.md), [ITransform](/engine/6000.3/script-reference/unityengine/uielements/itransform.md), [ITransitionAnimations](/engine/6000.3/script-reference/unityengine/uielements/experimental/itransitionanimations.md), [IExperimentalFeatures](/engine/6000.3/script-reference/unityengine/uielements/iexperimentalfeatures.md), [IVisualElementScheduler](/engine/6000.3/script-reference/unityengine/uielements/ivisualelementscheduler.md)

```csharp
public class OverlayToolbar : VisualElement, IEventHandler, IResolvedStyle, ITransform, ITransitionAnimations, IExperimentalFeatures, IVisualElementScheduler
```

## Remarks

Use this class with [ICreateHorizontalToolbar](/engine/6000.3/script-reference/unityeditor/overlays/icreatehorizontaltoolbar.md) and [ICreateVerticalToolbar](/engine/6000.3/script-reference/unityeditor/overlays/icreateverticaltoolbar.md) to build Overlays that are dockable in toolbars.

## Examples

```csharp
using System.Collections.Generic;
using UnityEditor;
using UnityEditor.Overlays;
using UnityEditor.Toolbars;
using UnityEngine;
using UnityEngine.UIElements;

[Overlay(typeof(SceneView), "My Toolbar Overlay")]
class MyOverlay : Overlay, ICreateToolbar
{
    public override VisualElement CreatePanelContent()
    {
        return new Label("I'm the content shown in panel mode!");
    }

    public IEnumerable<string> toolbarElements
    {
        get
        {
            yield return MyToolbarItem.id;
            yield return SomeOtherToolbarItem.id;
        }
    }
}

[EditorToolbarElement(id, typeof(SceneView))]
class SomeOtherToolbarItem : EditorToolbarToggle
{
    public const string id = "SomeOtherToolbarItem";

    public SomeOtherToolbarItem()
    {
        icon = EditorGUIUtility.FindTexture("CustomTool");
    }
}

// Example toolbar element with multiple controls
[EditorToolbarElement(id, typeof(SceneView))]
class MyToolbarItem : OverlayToolbar
{
    public const string id = "MyToolbarItem";

    public MyToolbarItem()
    {
        var icon = AssetDatabase.LoadAssetAtPath<Texture2D>("MyIcon");
        Add(new EditorToolbarButton(icon, () => { Debug.Log("Hello!"); }));
        Add(new EditorToolbarButton(icon, () => { Debug.Log("Hello again!"); }));
        SetupChildrenAsButtonStrip();
    }
}
```
