- java.util.EventObject
- - com.vaadin.flow.component.ComponentEvent<NativeDetails>
  - - com.vaadin.flow.component.html.NativeDetails.ToggleEvent

All Implemented Interfaces:

Serializable

Enclosing class:

NativeDetails
```
@DomEvent("toggle")
public static class NativeDetails.ToggleEvent
extends ComponentEvent<NativeDetails>
```
Represents the DOM event "toggle". In addition to the usual events supported by HTML elements, the details element supports the toggle event, which is dispatched to the details element whenever its state changes between open and closed. It is sent after the state is changed, although if the state changes multiple times before the browser can dispatch the event, the events are coalesced so that only one is sent.
