Struct sixtyfps_corelib::model::Repeater

pub struct Repeater<C: RepeatedComponent> { /* fields omitted */ }

This field is put in a component when using the for syntax It helps instantiating the components C

Implementations

impl<C: RepeatedComponent + 'static> Repeater<C>

pub fn ensure_updated(
    self: Pin<&Self>,
    init: impl Fn() -> VRc<ComponentVTable, C>
)

Call this function to make sure that the model is updated. The init function is the function to create a component

pub fn ensure_updated_listview(
    self: Pin<&Self>,
    init: impl Fn() -> VRc<ComponentVTable, C>,
    viewport_width: Pin<&Property<f32>>,
    viewport_height: Pin<&Property<f32>>,
    viewport_y: Pin<&Property<f32>>,
    listview_width: f32,
    listview_height: Pin<&Property<f32>>
)

Same as Self::ensuer_updated but for a ListView

pub fn model_set_row_data(self: Pin<&Self>, row: usize, data: C::Data)

Sets the data directly in the model

impl<C: RepeatedComponent> Repeater<C>

pub fn set_model_binding(
    &self,
    binding: impl Fn() -> ModelHandle<C::Data> + 'static
)

Set the model binding

pub fn visit(
    &self,
    order: TraversalOrder,
    visitor: ItemVisitorRefMut<'_>
) -> VisitChildrenResult

Call the visitor for each component

pub fn len(&self) -> usize

Return the amount of item currently in the component

pub fn is_empty(&self) -> bool

Return true if the Repeater is empty

pub fn components_vec(&self) -> Vec<VRc<ComponentVTable, C>>

Returns a vector containing all components

pub fn compute_layout_listview(
    &self,
    viewport_width: Pin<&Property<f32>>,
    listview_width: f32
) -> f32

Set the position of all the element in the listview

Returns the offset of the end of the last element

Trait Implementations

impl<C: RepeatedComponent> Default for Repeater<C>

fn default() -> Self

Returns the “default value” for a type.
