Struct i_slint_core::item_tree::ItemRc

#[repr(C)]
pub struct ItemRc { /* private fields */ }

A ItemRc is holding a reference to a ItemTree containing the item, and the index of this item

Implementations

impl ItemRc

pub fn new(item_tree: VRc<ItemTreeVTable>, index: u32) -> Self

Create an ItemRc from a ItemTree and an index

pub fn is_root_item_of(&self, item_tree: &VRc<ItemTreeVTable>) -> bool

pub fn borrow<'a>(&'a self) -> Pin<ItemRef<'a>>

Return a Pin<ItemRef<'a>>

pub fn downcast<T: HasStaticVTable<ItemVTable>>( &self ) -> Option<VRcMapped<ItemTreeVTable, T>>

Returns a VRcMapped of this item, to conveniently access specialized item API.

pub fn downgrade(&self) -> ItemWeak

pub fn parent_item(&self) -> Option<ItemRc>

Return the parent Item in the item tree.

pub fn is_visible(&self) -> bool

pub fn is_accessible(&self) -> bool

pub fn accessible_role(&self) -> AccessibleRole

pub fn accessible_string_property( &self, what: AccessibleStringProperty ) -> SharedString

pub fn geometry(&self) -> LogicalRect

pub fn map_to_window(&self, p: LogicalPoint) -> LogicalPoint

Returns an absolute position of p in the parent item coordinate system (does not add this item’s x and y)

pub fn map_to_item_tree( &self, p: LogicalPoint, item_tree: &VRc<ItemTreeVTable> ) -> LogicalPoint

Returns an absolute position of p in the ItemTree’s coordinate system (does not add this item’s x and y)

pub fn index(&self) -> u32

Return the index of the item within the ItemTree

pub fn item_tree(&self) -> &VRc<ItemTreeVTable>

Returns a reference to the ItemTree holding this item

pub fn first_child(&self) -> Option<Self>

The first child Item of this Item

pub fn last_child(&self) -> Option<Self>

The last child Item of this Item

pub fn previous_sibling(&self) -> Option<Self>

The previous sibling of this Item

pub fn next_sibling(&self) -> Option<Self>

The next sibling of this Item

pub fn previous_focus_item(&self) -> Self

Move tab focus to the previous item:

pub fn next_focus_item(&self) -> Self

Move tab focus to the next item:

Trait Implementations

impl Clone for ItemRc

fn clone(&self) -> ItemRc

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ItemRc

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ItemRc

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
