Struct embedded_text::style::TextBoxStyle

pub struct TextBoxStyle<C, F, A, V, H> where
    C: PixelColor,
    F: Font + Copy,  {
    pub text_style: TextStyle<C, F>,
    pub alignment: A,
    pub vertical_alignment: V,
    pub height_mode: H,
    pub line_spacing: i32,
    pub tab_size: TabSize<F>,
    pub underlined: bool,
    pub strikethrough: bool,
}

Styling options of a TextBox.

TextBoxStyle contains the Font, foreground and background PixelColor, line spacing, HeightMode, HorizontalTextAlignment and VerticalTextAlignment information necessary to draw a TextBox.

To construct a new TextBoxStyle object, use the new or from_text_style methods or the TextBoxStyleBuilder object.

Fields

text_style: TextStyle<C, F>

Style properties for text.

alignment: A

Horizontal text alignment.

vertical_alignment: V

Vertical text alignment.

height_mode: H

The height behaviour

line_spacing: i32

Desired space between lines, in pixels

tab_size: TabSize<F>

Desired column width for tabs

underlined: bool

If true, the text will be underlined

strikethrough: bool

If true, the text will be crossed out

Implementations

impl<C, F, A, V, H> TextBoxStyle<C, F, A, V, H> where
    C: PixelColor,
    F: Font + Copy,
    A: HorizontalTextAlignment,
    V: VerticalTextAlignment,
    H: HeightMode, 

pub fn new(
    font: F,
    text_color: C,
    alignment: A,
    vertical_alignment: V,
    height_mode: H
) -> Self

Creates a TextBoxStyle object with transparent background.

pub fn from_text_style(
    text_style: TextStyle<C, F>,
    alignment: A,
    vertical_alignment: V,
    height_mode: H
) -> Self

Creates a TextBoxStyle object from the given text style and alignment.

#[must_use]

pub fn measure_line<'a>(
    &self,
    parser: &mut Parser<'a>,
    carried_token: Option<Token<'a>>,
    max_line_width: u32
) -> (u32, u32, Option<Token<'a>>, bool)

Measure the width and count spaces in a single line of text.

Returns (width, rendered space count, carried token)

Instead of peeking ahead when processing tokens, this function advances the parser before processing a token. If a token opens a new line, it will be returned as the carried token. If the carried token is None, the parser has finished processing the text.

#[must_use]

pub fn measure_text_height(&self, text: &str, max_width: u32) -> u32

Measures text height when rendered using a given width.

Example: measure height of text when rendered using a 6x8 font and 72px width.

let style = TextBoxStyleBuilder::new(Font6x8)
    .text_color(BinaryColor::On)
    .build();

let height = style.measure_text_height(
    "Lorem Ipsum is simply dummy text of the printing and typesetting industry.",
    72,
);

// Expect 7 lines of text, wrapped in something like the following:

// |Lorem Ipsum |
// |is simply   |
// |dummy text  |
// |of the      |
// |printing and|
// |typesetting |
// |industry.   |

assert_eq!(7 * 8, height);
