Implementations

impl ComplexText

pub const FIELD_OFFSETS: ComplexTextFieldsOffsets = ComplexTextFieldsOffsets

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

impl ComplexText

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

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

pub fn text(self: Pin<&Self>) -> SharedString

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

pub fn font_weight(self: Pin<&Self>) -> i32

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

pub fn horizontal_alignment(self: Pin<&Self>) -> TextHorizontalAlignment

pub fn vertical_alignment(self: Pin<&Self>) -> TextVerticalAlignment

pub fn max_lines(self: Pin<&Self>) -> i32

pub fn font_family(self: Pin<&Self>) -> SharedString

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

pub fn wrap(self: Pin<&Self>) -> TextWrap

pub fn overflow(self: Pin<&Self>) -> TextOverflow

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

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

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

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

pub fn stroke_style(self: Pin<&Self>) -> TextStrokeStyle

impl ComplexText

pub fn font_metrics( self: Pin<&Self>, window_adapter: &Rc<dyn WindowAdapter>, self_rc: &ItemRc, ) -> FontMetrics

Trait Implementations

impl Default for ComplexText

fn default() -> Self

Returns the “default value” for a type.

impl HasFont for ComplexText

fn font_request(self: Pin<&Self>, self_rc: &ItemRc) -> FontRequest

impl HasStaticVTable<ItemVTable> for ComplexText

const STATIC_VTABLE: &'static ItemVTable

Safety: must point to the single static VTable for Self. Downcasts compare vtables by address, so it must not be a promoted temporary.

impl Item for ComplexText

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 MouseCursorInner, ) -> 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 MouseCursorInner, ) -> 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 ComplexText

const cached_rendering_data_offset: FieldOffset<ComplexText, CachedRenderingData>

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

impl RenderString for ComplexText

fn text(self: Pin<&Self>) -> PlainOrStyledText

fn max_lines(self: Pin<&Self>) -> i32

fn stroke(self: Pin<&Self>) -> (Brush, LogicalLength, TextStrokeStyle)

Stroke brush, width and style. The style is baked into the shaped glyphs, so it lives here (rather than in RenderText) to keep measuring and drawing shaping-identical.

fn line_limit(self: Pin<&Self>) -> Option<usize>

The maximum number of lines to lay out and render, from the max-lines property. Property values less than or equal to zero mean no limit.

fn link_color(self: Pin<&Self>) -> Color

Color of Style::Link spans. Like stroke, it’s baked into the shaped glyphs.

impl RenderText for ComplexText

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

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

fn alignment( self: Pin<&Self>, ) -> (TextHorizontalAlignment, TextVerticalAlignment)

fn wrap(self: Pin<&Self>) -> TextWrap

fn overflow(self: Pin<&Self>) -> TextOverflow

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

impl<'__dummy_lifetime> Unpin for ComplexText

where __MustNotImplUnpin<'__dummy_lifetime>: Unpin,
