Struct cosmic_text::TextBufferLine

pub struct TextBufferLine<'a> { /* private fields */ }

A line (or paragraph) of text that is shaped and laid out

Implementations

impl<'a> TextBufferLine<'a>

pub fn new<T: Into<String>>(text: T, attrs_list: AttrsList<'a>) -> Self

Create a new line with the given text and attributes list Cached shaping and layout can be done using the Self::shape and Self::layout functions

pub fn text(&self) -> &str

Get current text

pub fn set_text<T: AsRef<str> + Into<String>>(&mut self, text: T) -> bool

Set text

Will reset shape and layout if it differs from current text. Returns true if the line was reset

pub fn attrs_list(&self) -> &AttrsList<'a>

Get attributes list

pub fn set_attrs_list(&mut self, attrs_list: AttrsList<'a>) -> bool

Set attributes list

Will reset shape and layout if it differs from current attributes list. Returns true if the line was reset

pub fn wrap_simple(&self) -> bool

Get simple wrapping setting (wrap by characters only)

pub fn set_wrap_simple(&mut self, wrap_simple: bool) -> bool

Set simple wrapping setting (wrap by characters only)

Will reset shape and layout if it differs from current simple wrapping setting. Returns true if the line was reset

pub fn reset(&mut self)

Reset shaping and layout information

pub fn is_reset(&self) -> bool

Check if shaping and layout information is cleared

pub fn shape(&mut self, font_system: &'a FontSystem<'a>) -> &ShapeLine

Shape line, will cache results

pub fn layout(
    &mut self,
    font_system: &'a FontSystem<'a>,
    font_size: i32,
    width: i32
) -> &[LayoutLine]

Layout line, will cache results
