Struct RichText

pub struct RichText<Msg: Clone> { /* private fields */ }

A wrapped paragraph with clickable link ranges — the ltk counterpart of an Android Spanned carrying URLSpan / ClickableSpan. Each LinkSpan pairs a byte range with a Msg emitted on tap; the layout pass yields one hit rect per link line so taps land on the link rather than the paragraph.

Implementations

impl<Msg: Clone> RichText<Msg>

pub fn new(content: impl Into<String>) -> Self

A paragraph of content with no links: white text, the default blue link colour, default 16 px size and the canvas default font.

pub fn size(self, s: impl Into<Length>) -> Self

Set the font size.

pub fn color(self, c: Color) -> Self

Set the colour of non-link text.

pub fn link_color(self, c: Color) -> Self

Set the colour of link ranges (drawn underlined).

pub fn font( self, family: impl Into<String>, weight: u16, style: FontStyle, ) -> Self

Override the font with a (family, weight, style) triple resolved through the active theme’s font registry on draw.

pub fn link(self, start: usize, end: usize, msg: Msg) -> Self

Add a clickable range [start, end) (byte offsets) emitting msg.

pub fn preferred_size(&self, max_width: f32, canvas: &Canvas) -> (f32, f32)

pub fn draw(&self, canvas: &mut Canvas, rect: Rect)

pub fn link_rects(&self, rect: Rect, canvas: &Canvas) -> Vec<(Rect, Msg)>

Per-link hit rects for the layout pass: one rect per visual line a link covers, paired with the link’s message.
