Struct InlineText

#[repr(C)]
pub struct InlineText {
    pub lines: InlineLineVec,
    pub content_size: LogicalSize,
    pub font_size_px: f32,
    pub last_word_index: usize,
    pub baseline_descender_px: f32,
}

inline text so that hit-testing is easier

Fields

lines: InlineLineVec

List of lines, relative to (0.0, 0.0) representing the top left corner of the line

content_size: LogicalSize

Size of the text content, may be larger than the position of lines due to descending glyphs

font_size_px: f32

Size of the font used to layout this line

last_word_index: usize

Index of the last word

baseline_descender_px: f32

NOTE: descender is NEGATIVE (pixels from baseline to font size)

Implementations

impl InlineText

pub fn get_layouted_glyphs(&self) -> LayoutedGlyphs

Returns the final, positioned glyphs from an inline text

NOTE: It seems that at least in webrender, the glyphs have to be positioned in relation to the screen (instead of relative to the parent container)

The text_origin gets added to each glyph

NOTE: The lines in the text are relative to the TOP left corner (of the text, i.e. relative to the text_origin), but the word position is relative to the BOTTOM left corner (of the line bounds)

pub fn hit_test(&self, position: LogicalPosition) -> Vec<InlineTextHit>

Hit tests all glyphs, returns the hit glyphs - note that the result may be empty (no glyphs hit), or it may contain more than one result (overlapping glyphs - more than one glyph hit)

Usually the result will contain a single InlineTextHit

Trait Implementations

impl Clone for InlineText

fn clone(&self) -> InlineText

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InlineText

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for InlineText

fn eq(&self, other: &InlineText) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for InlineText

fn partial_cmp(&self, other: &InlineText) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
