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

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: u32) -> Pin<VRef<'_, ItemVTable>>

Return a reference to an item using the given index

fn get_subtree_range(self: Pin<&Self>, _1: u32) -> IndexRange

Return the range of indices below the dynamic ItemTreeNode at index

fn get_subtree( self: Pin<&Self>, _1: u32, _2: usize, _3: &mut VWeak<ItemTreeVTable, Dyn>, )

Return the ItemTreeRc 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 ItemTree. 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 ItemTree is a part of in the parent ItemTree.

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 embed_component( self: Pin<&Self>, _1: &VWeak<ItemTreeVTable>, _2: u32, ) -> bool

This embeds this ItemTree into the item tree of another ItemTree

Returns true if this ItemTree was embedded into the parent at parent_item_tree_index.

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 the root of the ItemTree

fn item_geometry(self: Pin<&Self>, _1: u32) -> LogicalRect

Returns the item’s geometry (relative to its parent item)

fn accessible_role(self: Pin<&Self>, _1: u32) -> AccessibleRole

Returns the accessible role for a given item

fn accessible_string_property( self: Pin<&Self>, _1: u32, _2: AccessibleStringProperty, _3: &mut SharedString, ) -> bool

Returns the accessible property via the result. Returns true if such a property exists.

fn accessibility_action(self: Pin<&Self>, _1: u32, _2: &AccessibilityAction)

Executes an accessibility action.

fn supported_accessibility_actions( self: Pin<&Self>, _1: u32, ) -> SupportedAccessibilityAction

Returns the supported accessibility actions.

fn item_element_infos(self: Pin<&Self>, _1: u32, _2: &mut SharedString) -> bool

Add the ElementName::id entries of the given item

fn window_adapter(self: Pin<&Self>, _1: bool, _2: &mut Option<WindowAdapterRc>)

Returns a Window, creating a fresh one if do_create is true.
