Struct i_slint_core::model::Repeater

pub struct Repeater<C: RepeatedComponent>(_);

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<Coord>>,
    viewport_height: Pin<&Property<Coord>>,
    viewport_y: Pin<&Property<Coord>>,
    listview_width: Coord,
    listview_height: Pin<&Property<Coord>>
)

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

pub fn set_model_binding(&self, binding: impl Fn() -> ModelRc<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 range(&self) -> (usize, usize)

Return the range of indices used by this Repeater.

Two values are necessary here since the Repeater can start to insert the data from its model at an offset.

pub fn component_at(&self, index: usize) -> Option<VRc<ComponentVTable, C>>

pub fn is_empty(&self) -> bool

Return true if the Repeater as 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<Coord>>,
    listview_width: Coord
) -> Coord

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.
