* **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), [IVisualElementScheduler](/engine/6000.3/script-reference/unityengine/uielements/ivisualelementscheduler.md), [IBindable](/engine/6000.3/script-reference/unityengine/uielements/ibindable.md), [INotifyValueChanged\<string>](/engine/6000.3/script-reference/unityengine/uielements/inotifyvaluechanged1.md), [ITextEdition](/engine/6000.3/script-reference/unityengine/uielements/itextedition.md), [ITextElementExperimentalFeatures](/engine/6000.3/script-reference/unityengine/uielements/itextelementexperimentalfeatures.md), [IExperimentalFeatures](/engine/6000.3/script-reference/unityengine/uielements/iexperimentalfeatures.md), [ITextSelection](/engine/6000.3/script-reference/unityengine/uielements/itextselection.md)

```csharp
public class PopupWindow : TextElement, IEventHandler, IResolvedStyle, ITransform, ITransitionAnimations, IVisualElementScheduler, IBindable, INotifyValueChanged<string>, ITextEdition, ITextElementExperimentalFeatures, IExperimentalFeatures, ITextSelection
```

## Remarks

The following screenshot is a visual representation of the popup window:

![Popup (PopupWindow)](/api/media?file=/engine/6000.3/media/images/Popup.png)

The following code generates the previous popup window:

## Examples

```csharp
var popupWindow = new UnityEngine.UIElements.PopupWindow() { text = "Title" };
popupWindow.Add(new Button());
```
