Trait Implementations

impl SystemParam for RowQuery<'_, '_>

type State = FetchState

Used to store data which persists across invocations of a system.

type Item<'w, 's> = RowQuery<'w, 's>

The item type returned when constructing this system param. The value of this associated type should be Self, instantiated with new lifetimes.

fn init_state(world: &mut World) -> Self::State

Creates a new instance of this param’s State.

fn init_access( state: &Self::State, system_meta: &mut SystemMeta, component_access_set: &mut FilteredAccessSet, world: &mut World, )

Registers any World access used by this SystemParam

fn apply(state: &mut Self::State, system_meta: &SystemMeta, world: &mut World)

Applies any deferred mutations stored in this SystemParam’s state. This is used to apply Commands during ApplyDeferred.

fn queue( state: &mut Self::State, system_meta: &SystemMeta, world: DeferredWorld<'_>, )

Queues any deferred mutations to be applied at the next ApplyDeferred.

unsafe fn validate_param<'w, 's>( state: &'s mut Self::State, _system_meta: &SystemMeta, _world: UnsafeWorldCell<'w>, ) -> Result<(), SystemParamValidationError>

Validates that the param can be acquired by the get_param.

unsafe fn get_param<'w, 's>( state: &'s mut Self::State, system_meta: &SystemMeta, world: UnsafeWorldCell<'w>, change_tick: Tick, ) -> Self::Item<'w, 's>

Creates a parameter to be passed into a SystemParamFunction.

impl<'w, 's> WidgetQuery<'w, 's> for RowQuery<'w, 's>

type WidgetView<'a> = RowWidget<'a, 'w, 's> where Self: 'a

The specific view struct this query returns (Ex, ButtonWidget, TextWidget).

fn get_components<'a>( &'a mut self, entity: Entity, ) -> Option<Self::WidgetView<'a>>

Get related components of an entity.

fn find_by_id<'a>(&'a mut self, target_id: &str) -> Option<Self::WidgetView<'a>>

Method to find widget by ID.

fn find_by_entity<'a>( &'a mut self, target_entity: Entity, ) -> Option<Self::WidgetView<'a>>

Method to find widget by Entity.

fn find_by_class(&self, target_class: &str) -> Vec<Entity>

Method to find entities that match with provided classes.

fn get_by_id<F>(&mut self, id: &str, f: F)

where F: for<'a> FnOnce(&mut Self::WidgetView<'a>),

Get the widget and executes a closure on a widget found by its ID.

fn get_by_entity<F>(&mut self, entity: Entity, f: F)

where F: for<'a> FnOnce(&mut Self::WidgetView<'a>),

Get the widget and executes a closure on a widget found by its Entity.

fn get_by_class<F>(&mut self, class: &str, f: F)

where F: for<'a> FnMut(&mut Self::WidgetView<'a>),

Executes a closure on every widget that matches the specified class.
