Struct bevy_iced::IcedContext

pub struct IcedContext<'w, 's, Message: Event> { /* private fields */ }

The context for interacting with Iced. Add this as a parameter to your system.

fn ui_system(..., mut ctx: IcedContext<UiMessage>) {
    let element = ...; // Build your element
    ctx.display(element);
}

IcedContext<T> requires an event system to be defined in the App. Do so by invoking app.add_event::<T>() when constructing your App.

Implementations

impl<'w, 's, M: Event> IcedContext<'w, 's, M>

pub fn display<'a>(&'a mut self, element: impl Into<Element<'a, M, Renderer>>)

Display an Element to the screen.

Trait Implementations

impl<Message: Event> SystemParam for IcedContext<'_, '_, Message>

type State = FetchState<Message>

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

type Item<'w, 's> = IcedContext<'w, 's, Message>

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, system_meta: &mut SystemMeta) -> Self::State

Registers any World access used by this SystemParam and creates a new instance of this param’s State.

fn new_archetype( state: &mut Self::State, archetype: &Archetype, system_meta: &mut SystemMeta )

For the specified Archetype, registers the components accessed by this SystemParam (if applicable).

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 apply_system_buffers.

unsafe fn get_param<'w, 's>( state: &'s mut Self::State, system_meta: &SystemMeta, world: &'w World, change_tick: u32 ) -> Self::Item<'w, 's>
