where S: Res<U> + 'static, U: Clone + 'static, C: Res<R> + 'static, R: Deref<Target = [TreeTableColumn<TreeNodeRow<Id>, Id, H, K>]> + Clone + 'static,

Creates a VirtualTreeTable directly from hierarchical data.

Provide closures to enumerate root node IDs and child node IDs for a given parent. The order returned by those closures is preserved; filtering only removes hidden nodes and their descendants. The table manages expand/collapse state and internally projects IDs into TreeNodeRow values.

Trait Implementations

impl<T, V, Id, H, K> View for VirtualTreeTable<T, V, Id, H, K>

fn element(&self) -> Option<&'static str>

Specifies a name for the view type which can be used as an element selector in css.

fn event(&mut self, cx: &mut EventContext<'_>, event: &mut Event)

Handles any events received by the view.

fn build<F>(self, cx: &mut Context, content: F) -> Handle<'_, Self>

where F: FnOnce(&mut Context),

Builds the view into the tree and returns a handle which can be used to apply style and layout modifiers to the view.

fn draw(&self, cx: &mut DrawContext<'_>, canvas: &Canvas)

Provides custom drawing for the view.

fn accessibility(&self, cx: &mut AccessContext<'_>, node: &mut AccessNode)

Provides a way to configure the accessibility features of a view.
