Struct Layer

Source
#[repr(C)]
pub struct Layer { pub cache_rendering_hint: Property<bool>, pub cached_rendering_data: CachedRenderingData, }
Expand description

The Layer Item is not meant to be used directly by the .slint code, instead, the layer: xxx property should be used

Fields§

Implementations§

Source§

impl Layer

Source

pub const FIELD_OFFSETS: LayerFieldsOffsets

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

Source§

impl Layer

Source

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

Trait Implementations§

Source§

impl Default for Layer

Source§

fn default() -> Layer

Returns the “default value” for a type. Read more
Source§

impl HasStaticVTable<ItemVTable> for Layer

Source§

fn static_vtable() -> &'static ItemVTable

Safety: must be a valid VTable for Self
Source§

impl Item for Layer

Source§

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.
Source§

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
Source§

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.
Source§

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

Handle input event for mouse and touch event
Source§

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

Source§

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

Source§

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

Source§

impl ItemConsts for Layer

Source§

const cached_rendering_data_offset: FieldOffset<Layer, CachedRenderingData>

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