Struct TextOverflowInfo

source
pub struct TextOverflowInfo {
    pub line: usize,
    pub text_char: usize,
    pub included_glyphs: SmallVec<[Range<usize>; 1]>,
    pub suffix_origin: Point2D<f32, Px>,
}
Expand description

Info about a shaped text overflow in constraint.

Can be computed using ShapedText::overflow_info.

Fields§

§line: usize

First overflow line.

All segments in this line and next lines are fully overflown. The previous line may be partially overflown, the lines before that are fully visible.

Is the ShapedText::lines_len if the last line is fully visible.

§text_char: usize

First overflow character in the text.

Note that if overflow is not wrapping (single text line) the char may not cover all visible glyphs in the line if it is bidirectional.

§included_glyphs: SmallVec<[Range<usize>; 1]>

Glyphs not overflown in the last not overflown line.

If the line is not bidirectional this will be a single range covering the not overflow glyphs, if it is bidi multiple ranges are possible due to bidi reordering.

§suffix_origin: Point2D<f32, Px>

Placement of the suffix (ellipses or custom).

The suffix must be of the width given to ShapedText::overflow_info and the same line height as the text.
