ActionBuilder

Struct ActionBuilder 

Source
pub struct ActionBuilder { /* private fields */ }
Expand description

Fluent builder for Action. Use ActionBuilder::on_invoke for the common case (handler consumes the intent) or ActionBuilder::on_invoke_with_response when the handler needs to decide whether to propagate.

Implementations§

Source§

impl ActionBuilder

Source

pub fn enabled_when(self, signal: impl Into<Prop<bool>>) -> Self

Reactive enabled-predicate. When the signal holds false the action is skipped during dispatch.

Source

pub fn on_invoke( self, f: impl FnMut(&Intent, &mut EventContext<'_>) + 'static, ) -> Action

Register a handler that consumes the intent. The handler’s return value is ignored; the framework treats every invocation as IntentResponse::Handled.

Source

pub fn on_invoke_with_response( self, f: impl FnMut(&Intent, &mut EventContext<'_>) -> IntentResponse + 'static, ) -> Action

Register a handler whose return value decides whether the intent propagates to ancestor widgets. Use when a widget wants to observe an intent (e.g., update a draft status) while still letting an ancestor perform the primary action.
