A Component is representing an unit that is allocated together Note: Was generated from the #[vtable] macro on ComponentVTable

Required Methods

fn visit_children_item(
    self: Pin<&Self>,
    _1: isize,
    _2: TraversalOrder,
    _3: VRefMut<'_, ItemVisitorVTable>
) -> VisitChildrenResult

Visit the children of the item at index index. Note that the root item is at index 0, so passing 0 would visit the item under root (the children of root). If you want to visit the root item, you need to pass -1 as an index.

fn get_item_ref(self: Pin<&Self>, _1: usize) -> Pin<VRef<'_, ItemVTable>>

Return a reference to an item using the given index

fn get_subtree_range(self: Pin<&Self>, _1: usize) -> IndexRange

Return the range of indices below the dynamic ItemTreeNode at index

fn get_subtree_component(
    self: Pin<&Self>,
    _1: usize,
    _2: usize,
    _3: &mut VWeak<ComponentVTable, Dyn>
)

Return the ComponentRc at subindex below the dynamic ItemTreeNode at index

fn get_item_tree(self: Pin<&Self>) -> Slice<'_, ItemTreeNode>

Return the item tree that is defined by this Component. The return value is an item weak because it can be null if there is no parent. And the return value is passed by &mut because ItemWeak has a destructor

fn parent_node(self: Pin<&Self>, _1: &mut ItemWeak)

Return the node this component is a part of in the parent component.

The return value is an item weak because it can be null if there is no parent. And the return value is passed by &mut because ItemWeak has a destructor Note that the returned value will typically point to a repeater node, which is strictly speaking not an Item at all!

fn subtree_index(self: Pin<&Self>) -> usize

Return the index of the current subtree or usize::MAX if this is not a subtree

fn layout_info(self: Pin<&Self>, _1: Orientation) -> LayoutInfo

Returns the layout info for this component

fn accessible_role(self: Pin<&Self>, _1: usize) -> AccessibleRole

Returns the accessible role for a given item

fn accessible_string_property(
    self: Pin<&Self>,
    _1: usize,
    _2: AccessibleStringProperty,
    _3: &mut SharedString
)

Returns the accessible property
