Expand description
Built-in GlyphPositioner
implementations.
Takes generic LineBreaker
to indicate the wrapping style.
See BuiltInLineBreaker
.
Example
let layout = Layout::default().h_align(HorizontalAlign::Right);
Variants§
SingleLine
Renders a single line from left-to-right according to the inner alignment. Hard breaking will end the line, partially hitting the width bound will end the line.
Wrap
Renders multiple lines from left-to-right according to the inner alignment. Hard breaking characters will cause advancement to another line. A characters hitting the width bound will also cause another line to start.
Implementations§

fn calculate_glyphs<F, S>( &self, fonts: &[F], geometry: &SectionGeometry, sections: &[S] ) -> Vec<SectionGlyph, Global>where F: Font, S: ToSectionText,
Calculate a sequence of positioned glyphs to render. Custom implementations should
return the same result when called with the same arguments to allow layout caching.
§fn bounds_rect(&self, geometry: &SectionGeometry) -> Rect
fn bounds_rect(&self, geometry: &SectionGeometry) -> Rect
Return a screen rectangle according to the requested render position and bounds
appropriate for the glyph layout.

Recalculate a glyph sequence after a change. Read more
