Implementations

impl ComponentContainer

pub const FIELD_OFFSETS: ComponentContainerFieldsOffsets

Return a struct containing the offset of for the fields of this struct

impl ComponentContainer

pub fn width(self: Pin<&Self>) -> LogicalLength

pub fn height(self: Pin<&Self>) -> LogicalLength

pub fn component_factory(self: Pin<&Self>) -> ComponentFactory

pub fn has_component(self: Pin<&Self>) -> bool

impl ComponentContainer

pub fn ensure_updated(self: Pin<&Self>)

pub fn subtree_range(self: Pin<&Self>) -> IndexRange

pub fn subtree_component(self: Pin<&Self>) -> ItemTreeWeak

pub fn visit_children_item( self: Pin<&Self>, _index: isize, order: TraversalOrder, visitor: VRefMut<'_, ItemVisitorVTable>, ) -> VisitChildrenResult

Trait Implementations

impl Default for ComponentContainer

fn default() -> ComponentContainer

Returns the “default value” for a type.

impl HasStaticVTable<ItemVTable> for ComponentContainer

fn static_vtable() -> &'static ItemVTable

Safety: must be a valid VTable for Self

impl Item for ComponentContainer

fn init(self: Pin<&Self>, self_rc: &ItemRc)

This function is called by the run-time after the memory for the item has been allocated and initialized. It will be called before any user specified bindings are set.

fn layout_info( self: Pin<&Self>, orientation: Orientation, _window_adapter: &Rc<dyn WindowAdapter>, ) -> LayoutInfo

We would need max/min/preferred size, and all layout info

fn input_event_filter_before_children( self: Pin<&Self>, _: MouseEvent, _window_adapter: &Rc<dyn WindowAdapter>, _self_rc: &ItemRc, ) -> InputEventFilterResult

Event handler for mouse and touch event. This function is called before being called on children. Then, depending on the return value, it is called for the children, and their children, then Self::input_event is called on the children, and finally Self::input_event is called on this item again.

fn input_event( self: Pin<&Self>, _: MouseEvent, _window_adapter: &Rc<dyn WindowAdapter>, _self_rc: &ItemRc, ) -> InputEventResult

Handle input event for mouse and touch event

fn focus_event( self: Pin<&Self>, _: &FocusEvent, _window_adapter: &Rc<dyn WindowAdapter>, _self_rc: &ItemRc, ) -> FocusEventResult

fn key_event( self: Pin<&Self>, _: &KeyEvent, _window_adapter: &Rc<dyn WindowAdapter>, _self_rc: &ItemRc, ) -> KeyEventResult

fn render( self: Pin<&Self>, backend: &mut &'_ mut dyn ItemRenderer, item_rc: &ItemRc, size: LogicalSize, ) -> RenderingResult

impl ItemConsts for ComponentContainer

const cached_rendering_data_offset: FieldOffset<ComponentContainer, CachedRenderingData>

offset in bytes from the *const ItemImpl. isize::MAX means None

impl<'__dummy_lifetime> Unpin for ComponentContainer

where __MustNotImplUnpin<'__dummy_lifetime>: Unpin,
