Struct MultiLineText

pub struct MultiLineText<'a, Coord, T>
where
    T: Borrow<str>,
{ /* private fields */ }

An multi-line text element. The Text element allows only single line text and the MultiLineText supports drawing multiple lines

Implementations

impl<'a, Coord, T> MultiLineText<'a, Coord, T>

where T: Borrow<str>,

pub fn new<S>(pos: Coord, style: S) -> MultiLineText<'a, Coord, T>

where S: Into<TextStyle<'a>>,

Create an empty multi-line text element. Lines can be append to the empty multi-line by calling push_line method

pos: The upper left corner style: The style of the text

pub fn set_line_height( &mut self, value: f64, ) -> &mut MultiLineText<'a, Coord, T>

Set the line height of the multi-line text element

pub fn push_line<L>(&mut self, line: L)

where L: Into<T>,

Push a new line into the given multi-line text line: The line to be pushed

pub fn estimate_dimension( &self, ) -> Result<(i32, i32), <FontDataInternal as FontData>::ErrorType>

Estimate the multi-line text element’s dimension

pub fn relocate(&mut self, coord: Coord)

Move the location to the specified location

impl<'a, T> MultiLineText<'a, (i32, i32), T>

where T: Borrow<str>,

pub fn compute_line_layout( &self, ) -> Result<Vec<((i32, i32), (i32, i32))>, <FontDataInternal as FontData>::ErrorType>

Compute the line layout

impl<'a, Coord> MultiLineText<'a, Coord, &'a str>

pub fn from_str<ST, S>( text: ST, pos: Coord, style: S, max_width: u32, ) -> MultiLineText<'a, Coord, &'a str>

where ST: Into<&'a str>, S: Into<TextStyle<'a>>,

Parse a multi-line text into an multi-line element.

text: The text that is parsed pos: The position of the text style: The style for this text max_width: The width of the multi-line text element, the line will break into two lines if the line is wider than the max_width. If 0 is given, do not do any line wrapping

impl<'a, Coord> MultiLineText<'a, Coord, String>

pub fn from_string<S>( text: String, pos: Coord, style: S, max_width: u32, ) -> MultiLineText<'a, Coord, String>

where S: Into<TextStyle<'a>>,

Parse a multi-line text into an multi-line element.

text: The text that is parsed pos: The position of the text style: The style for this text max_width: The width of the multi-line text element, the line will break into two lines if the line is wider than the max_width. If 0 is given, do not do any line wrapping

Trait Implementations

impl<'a, Coord, DB, T> Drawable<DB> for MultiLineText<'a, Coord, T>

where Coord: 'a, DB: DrawingBackend, T: Borrow<str>,

fn draw<I>( &self, points: I, backend: &mut DB, _: (u32, u32), ) -> Result<(), DrawingErrorKind<<DB as DrawingBackend>::ErrorType>>

where I: Iterator<Item = (i32, i32)>,

Actually draws the element. The key points is already translated into the image coordinate and can be used by DC directly

impl<'b, 'a, Coord, T> PointCollection<'a, Coord> for &'a MultiLineText<'b, Coord, T>

where Coord: 'a, T: Borrow<str> + 'a,

type Point = &'a Coord

The item in point iterator

type IntoIter = Once<&'a Coord>

The point iterator

fn point_iter( self, ) -> <&'a MultiLineText<'b, Coord, T> as PointCollection<'a, Coord>>::IntoIter

framework to do the coordinate mapping
