Implementations

impl Flickable

pub const FIELD_OFFSETS: FlickableFieldsOffsets

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

impl Flickable

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

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

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

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

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

Trait Implementations

impl Default for Flickable

fn default() -> Flickable

Returns the “default value” for a type.

impl HasStaticVTable<ItemVTable> for Flickable

fn static_vtable() -> &'static ItemVTable

Safety: must be a valid VTable for Self

impl Item for Flickable

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>,
    event: 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>,
    event: 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)

impl ItemConsts for Flickable

const cached_rendering_data_offset: FieldOffset<Self, CachedRenderingData>

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