Implementations

impl ImageItem

pub const FIELD_OFFSETS: ImageItemFieldsOffsets

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

impl ImageItem

pub fn source(self: Pin<&Self>) -> Image

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

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

pub fn image_fit(self: Pin<&Self>) -> ImageFit

pub fn image_rendering(self: Pin<&Self>) -> ImageRendering

pub fn colorize(self: Pin<&Self>) -> Brush

Trait Implementations

impl Default for ImageItem

fn default() -> ImageItem

Returns the “default value” for a type.

impl HasStaticVTable<ItemVTable> for ImageItem

fn static_vtable() -> &'static ItemVTable

Safety: must be a valid VTable for Self

impl Item for ImageItem

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

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

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

impl ItemConsts for ImageItem

const cached_rendering_data_offset: FieldOffset<ImageItem, CachedRenderingData>

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

impl RenderImage for ImageItem

fn target_size(self: Pin<&Self>) -> LogicalSize

fn source(self: Pin<&Self>) -> Image

fn source_clip(self: Pin<&Self>) -> Option<IntRect>

fn image_fit(self: Pin<&Self>) -> ImageFit

fn rendering(self: Pin<&Self>) -> ImageRendering

fn colorize(self: Pin<&Self>) -> Brush

fn alignment( self: Pin<&Self>, ) -> (ImageHorizontalAlignment, ImageVerticalAlignment)

fn tiling(self: Pin<&Self>) -> (ImageTiling, ImageTiling)

impl<'__dummy_lifetime> Unpin for ImageItem

where __MustNotImplUnpin<'__dummy_lifetime>: Unpin,
