impl Rotate

pub fn angle(self: Pin<&Self>) -> f32

pub fn origin_y(self: Pin<&Self>) -> Coord

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

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

Trait Implementations

impl Default for Rotate

fn default() -> Rotate

Returns the “default value” for a type.

impl HasStaticVTable<ItemVTable> for Rotate

fn static_vtable() -> &'static ItemVTable

Safety: must be a valid VTable for Self

impl Item for Rotate

fn init(self: Pin<&Self>, _window: &WindowRc)

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 geometry(self: Pin<&Self>) -> Rect

Returns the geometry of this item (relative to its parent item)

fn layout_info(
    self: Pin<&Self>,
    _orientation: Orientation,
    _window: &WindowRc
) -> LayoutInfo

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

fn input_event_filter_before_children(
    self: Pin<&Self>,
    _: MouseEvent,
    _window: &WindowRc,
    _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: &WindowRc,
    _self_rc: &ItemRc
) -> InputEventResult

Handle input event for mouse and touch event

fn key_event(
    self: Pin<&Self>,
    _: &KeyEvent,
    _window: &WindowRc
) -> KeyEventResult

fn focus_event(
    self: Pin<&Self>,
    _: &FocusEvent,
    _window: &WindowRc
) -> FocusEventResult

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

impl ItemConsts for Rotate

const cached_rendering_data_offset: FieldOffset<Rotate, CachedRenderingData> = Rotate::FIELD_OFFSETS.cached_rendering_data.as_unpinned_projection()

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

impl<'__dummy_lifetime> Unpin for Rotate where
    __MustNotImplUnpin<'__dummy_lifetime>: Unpin,
