Implementations§

Source§

impl Rotate

Source

pub const FIELD_OFFSETS: RotateFieldsOffsets

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

Source§

impl Rotate

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

Source

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

Source

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

Trait Implementations§

Source§

impl Default for Rotate

Source§

fn default() -> Rotate

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

impl HasStaticVTable<ItemVTable> for Rotate

Source§

fn static_vtable() -> &'static ItemVTable

Safety: must be a valid VTable for Self
Source§

impl Item for Rotate

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 Rotate

Source§

const cached_rendering_data_offset: FieldOffset<Rotate, CachedRenderingData>

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

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