Fields

keys: Property<Keys>

enabled: Property<bool>

activated: Callback<VoidArg>

cached_rendering_data: CachedRenderingData

Implementations

impl KeyBinding

pub const FIELD_OFFSETS: KeyBindingFieldsOffsets = KeyBindingFieldsOffsets

Return a zero-sized helper whose methods return field offsets.

impl KeyBinding

pub fn keys(self: Pin<&Self>) -> Keys

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

Trait Implementations

impl Default for KeyBinding

fn default() -> KeyBinding

Returns the “default value” for a type.

impl HasStaticVTable<ItemVTable> for KeyBinding

fn static_vtable() -> &'static ItemVTable

Safety: must be a valid VTable for Self

impl Item for KeyBinding

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 deinit(self: Pin<&Self>, _window_adapter: &Rc<dyn WindowAdapter>)

fn layout_info( self: Pin<&Self>, _orientation: Orientation, _cross_axis_constraint: Coord, _window_adapter: &Rc<dyn WindowAdapter>, _self_rc: &ItemRc, ) -> LayoutInfo

We would need max/min/preferred size, and all layout info. cross_axis_constraint is the available width when querying vertical layout info, enabling height-for-width (Text word-wrap, Image aspect ratio). Negative values mean unconstrained.

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

Handle input event for mouse and touch event

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

Called on the parents of the focused item, allowing for global shortcuts and similar overrides of the default actions.

fn key_event( self: Pin<&Self>, _: &InternalKeyEvent, _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

fn bounding_rect( self: Pin<&Self>, _window_adapter: &Rc<dyn WindowAdapter>, _self_rc: &ItemRc, geometry: LogicalRect, ) -> LogicalRect

Returns the rendering bounding rect for that particular item in the parent’s item coordinate (same coordinate system as the geometry)

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

impl ItemConsts for KeyBinding

const cached_rendering_data_offset: FieldOffset<KeyBinding, CachedRenderingData>

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

impl<'__dummy_lifetime> Unpin for KeyBinding

where __MustNotImplUnpin<'__dummy_lifetime>: Unpin,
