Function on_node_op 

pub fn on_node_op(
    child: impl IntoUiNode,
    handler: Box<dyn FnMut(&OnNodeOpArgs) -> HandlerResult + Send>,
) -> UiNode

P On any node operation.

This property calls handler for any widget node operation, after the widget content has processed the operation. This means that the handler is raised after any on_pre_node_op handler. Note that properties of NestGroup::EVENT or lower can still process the operation before this event.

Handlers

This property accepts any Handler<A>, including the async handlers. Use one of the handler macros, hn!, hn_once!, async_hn! or async_hn_once!, to declare a handler closure.

Async

The async handlers spawn a task that is associated with the widget, it will only update when the widget updates, so the task pauses when the widget is deinited, and is canceled when the widget is dropped.
