Struct i_slint_core::item_tree::ItemRc

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

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

Implementations

impl ItemRc

pub fn new(component: VRc<ComponentVTable>, index: usize) -> Self

Create an ItemRc from a component and an index

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

Return a Pin<ItemRef<'a>>

pub fn downcast<'a, T: HasStaticVTable<ItemVTable>>(
    &'a self
) -> Option<VRcMapped<ComponentVTable, 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 index(&self) -> usize

Return the index of the item within the component

pub fn component(&self) -> VRc<ComponentVTable>

Returns a reference to the component 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<ItemRc> 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.
