# Widget class

Namespace: [Eto](https://eto.picoe.ca/api/namespace/eto.md) · Assembly: [Eto](https://eto.picoe.ca/api/assembly/eto.md)

```cs
[RuntimeNameProperty("ID")]
public abstract class Widget : IHandlerSource, IDisposable, ICallbackSource
```

Base widget class for all objects requiring a platform-specific implementation

**Remarks:** The Widget is the base of all abstracted objects that have platform-specific implementations. To implement the handler for a widget, use the [WidgetHandler<TWidget>](https://eto.picoe.ca/api/type/eto.widgethandler-1.md) as the base class.
