Struct bevy_ui_navigation::events::NavEventReader
source · pub struct NavEventReader<'w, 's, 'a> { /* private fields */ }Expand description
A wrapper for EventReader<NavEvent> to simplify dealing with NavEvents.
Implementations§
sourcepub fn with_request(
&mut self,
request: NavRequest
) -> impl Iterator<Item = Entity> + '_
pub fn with_request( &mut self, request: NavRequest ) -> impl Iterator<Item = Entity> + '_
Iterate over NavEvent::NoChanges focused entity
triggered by request type requests.
sourcepub fn activated(&mut self) -> impl Iterator<Item = Entity> + '_
pub fn activated(&mut self) -> impl Iterator<Item = Entity> + '_
Iterate over activated Focusables.
A Focusable is activated when a NavRequest::Action is sent
while it is focused, and it doesn’t lead to a new menu.
sourcepub fn types(&mut self) -> impl Iterator<Item = (&NavEvent, Entity)> + '_
pub fn types(&mut self) -> impl Iterator<Item = (&NavEvent, Entity)> + '_
Iterate over NavEvents, associating them
with the “relevant” entity of the event.
sourcepub fn activated_in_query<'b, 'c: 'b, Q: ReadOnlyWorldQuery, F: ReadOnlyWorldQuery>(
&'b mut self,
query: &'c Query<'_, '_, Q, F>
) -> impl Iterator<Item = Q::Item<'c>> + 'b
pub fn activated_in_query<'b, 'c: 'b, Q: ReadOnlyWorldQuery, F: ReadOnlyWorldQuery>( &'b mut self, query: &'c Query<'_, '_, Q, F> ) -> impl Iterator<Item = Q::Item<'c>> + 'b
Iterate over query items of activated focusables.
See Self::activated for meaning of “activated”.
sourcepub fn activated_in_query_foreach_mut<Q: WorldQuery, F: ReadOnlyWorldQuery>(
&mut self,
query: &mut Query<'_, '_, Q, F>,
for_each: impl FnMut(Q::Item<'_>)
)
pub fn activated_in_query_foreach_mut<Q: WorldQuery, F: ReadOnlyWorldQuery>( &mut self, query: &mut Query<'_, '_, Q, F>, for_each: impl FnMut(Q::Item<'_>) )
Run for_each with result of query for each activated entity.
Unlike Self::activated_in_query this works with mutable queries.
see Self::activated for meaning of “activated”.
Auto Trait Implementations§
Blanket Implementations§
§fn as_bind_group_shader_type(&self, _images: &RenderAssets<Image>) -> U
fn as_bind_group_shader_type(&self, _images: &RenderAssets<Image>) -> U
Return the
T [ShaderType] for self. When used in [AsBindGroup]
derives, it is safe to assume that all images in self exist.§fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>
fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>
Convert
Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can
then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>
fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>
Convert
Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be
further downcast into Rc<ConcreteType> where ConcreteType implements Trait.§fn as_any(&self) -> &(dyn Any + 'static)
fn as_any(&self) -> &(dyn Any + 'static)
Convert
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s.§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Convert
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s.
