Extension trait over TextApi
Provided methods
pub fn update_env<F: FnOnce(&mut UpdateEnv<'_>)>(&mut self, f: F) -> Vec2
[src]
Update the environment and prepare, returning required size
This prepares text as necessary. It always performs line-wrapping.
pub fn required_action(&self) -> Action
[src]
Get required action
pub fn num_lines(&self) -> usize
[src]
Get the number of lines
Wraps TextDisplay::num_lines
.
pub fn find_line(&self, index: usize) -> Option<(usize, Range<usize>)>
[src]
Find the line containing text index
Wraps TextDisplay::find_line
.
pub fn line_range(&self, line: usize) -> Option<Range<usize>>
[src]
Get the range of a line, by line number
Wraps TextDisplay::line_range
.
pub fn line_is_ltr(&self, line: usize) -> bool
[src]
Get the directionality of the current line
Wraps TextDisplay::line_is_ltr
.
pub fn line_is_rtl(&self, line: usize) -> bool
[src]
Get the directionality of the current line
Wraps TextDisplay::line_is_rtl
.
pub fn text_index_nearest(&self, pos: Vec2) -> usize
[src]
Find the text index for the glyph nearest the given pos
pub fn line_index_nearest(&self, line: usize, x: f32) -> Option<usize>
[src]
Find the text index nearest horizontal-coordinate x
on line
pub fn text_glyph_pos(&self, index: usize) -> MarkerPosIterⓘNotable traits for MarkerPosIter
impl Iterator for MarkerPosIter type Item = MarkerPos;
[src]
Notable traits for MarkerPosIter
impl Iterator for MarkerPosIter type Item = MarkerPos;
Find the starting position (top-left) of the glyph at the given index
Wraps TextDisplay::text_glyph_pos
.
pub fn num_glyphs(&self) -> usize
[src]
Get the number of glyphs
Wraps TextDisplay::num_glyphs
.
pub fn glyphs<F: FnMut(FontId, f32, f32, Glyph)>(&self, f: F)
[src]
Yield a sequence of positioned glyphs
Wraps TextDisplay::glyphs
.
pub fn glyphs_with_effects<X, F, G>(&self, effects: &[Effect<X>], f: F, g: G) where
X: Copy + Default,
F: FnMut(FontId, f32, f32, Glyph, usize, X),
G: FnMut(f32, f32, f32, f32, usize, X),
[src]
X: Copy + Default,
F: FnMut(FontId, f32, f32, Glyph, usize, X),
G: FnMut(f32, f32, f32, f32, usize, X),
Like TextDisplay::glyphs
but with added effects
pub fn highlight_lines(&self, range: Range<usize>) -> Vec<(Vec2, Vec2)>
[src]
Yield a sequence of rectangles to highlight a given range, by lines
Wraps TextDisplay::highlight_lines
.
pub fn highlight_runs(&self, range: Range<usize>) -> Vec<(Vec2, Vec2)>
[src]
Yield a sequence of rectangles to highlight a given range, by runs
Wraps TextDisplay::highlight_runs
.
