Struct pango::HitPosition

source ·
pub struct HitPosition { /* private fields */ }
Expand description

The result of LayoutLine::x_to_index.

Implementations§

source§

impl HitPosition

source

pub fn index(self) -> i32

The UTF-8 byte offset of the grapheme closest to the position.

This position is relative to the start of the Layout’s text.

source

pub fn trailing(self) -> i32

The codepoint within the grapheme of the position.

This will always be either 0, or the number of chars (not bytes!) in the grapheme. This represents whether the user clicked near the start of the grapheme or near the end; this is important for things like resolving cursor positions.

source

pub fn is_inside(self) -> bool

Whether or not the position was within the bounds of the line.

If this is false, then index and trailing will always resolve to either the very first or the very last position in the line; this behaviour is dependent on the line’s resolved writing direction.
