Struct Repeater

pub struct Repeater<C: RepeatedItemTree>(/* private fields */);

Implementations

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

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

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

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

Same as Self::ensure_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 the root of each instance

pub fn len(&self) -> usize

Return the amount of instances currently in the repeater

pub fn range(&self) -> Range<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 instance_at(&self, index: usize) -> Option<VRc<ItemTreeVTable, C>>

Return the instance for the given model index. The index should be within Self::range()

pub fn is_empty(&self) -> bool

Return true if the Repeater as empty

pub fn instances_vec(&self) -> Vec<VRc<ItemTreeVTable, C>>

Returns a vector containing all instances

Trait Implementations

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

fn default() -> Self

Returns the “default value” for a type.
