Struct TextLayout 

pub struct TextLayout(/* private fields */);

The Layout for TextElement. This can be used to map indices to pixels and vice versa.

Implementations

impl TextLayout

pub fn evaluate_wrap_width( white_space: &WhiteSpace, known_dimensions: Size<Option<Pixels>>, available_space: Size<AvailableSpace>, ) -> Option<Pixels>

Evaluates the width to wrap the text at.

pub fn evaluate_overflow( text_style: &TextStyle, known_dimensions: Size<Option<Pixels>>, available_space: Size<AvailableSpace>, ) -> TextLayoutTruncation

Evaluates how truncation should be applied if the text overflows the available space.

pub fn apply_truncation<'runs>( text: SharedString, text_style: &TextStyle, font_size: Pixels, line_height: Pixels, wrap_width: Option<Pixels>, truncation: &TextLayoutTruncation, runs: &'runs [TextRun], window: &mut Window, cx: &mut App, ) -> (SharedString, Cow<'runs, [TextRun]>)

Conditionally applies truncation to some text and outputs how the text should be displayed.

pub fn index_for_position( &self, position: Point<Pixels>, ) -> Result<usize, usize>

Get the byte index into the input of the pixel position.

pub fn position_for_index(&self, index: usize) -> Option<Point<Pixels>>

Get the pixel position for the given byte index.

pub fn line_layout_for_index( &self, index: usize, ) -> Option<Arc<WrappedLineLayout>>

Retrieve the layout for the line containing the given byte index.

pub fn line_layouts(&self) -> SmallVec<[Arc<WrappedLineLayout>; 1]>

Retrieve all line layouts in source order.

pub fn bounds(&self) -> Bounds<Pixels>

The bounds of this layout.

pub fn line_height(&self) -> Pixels

The line height for this layout.

pub fn len(&self) -> usize

The UTF-8 length of the underlying text.

pub fn text(&self) -> String

The text for this layout.

pub fn wrapped_text(&self) -> String

The text for this layout (with soft-wraps as newlines)
