Struct TextCursor

pub struct TextCursor { /* private fields */ }

Implementations

impl TextCursor

pub fn position(&self) -> usize

pub fn anchor_position(&self) -> usize

pub fn set_position(&mut self, position: usize, move_mode: MoveMode)

set the cursor position, with or without the anchor depending of move_mode. Ensure that the cursor position is in the document.

pub fn current_block(&self) -> Weak<Block>

Give the current block under the cursor position

pub fn set_block_format( &mut self, block_format: &BlockFormat, ) -> Result<(), ModelError>

pub fn merge_block_format( &mut self, block_format: &BlockFormat, ) -> Result<(), ModelError>

pub fn insert_block(&mut self) -> Result<Weak<Block>, ModelError>

pub fn current_frame(&self) -> Weak<Frame>

Give the current frame under the cursor position

pub fn set_frame_format( &mut self, frame_format: &FrameFormat, ) -> Result<(), ModelError>

pub fn merge_frame_format( &mut self, frame_format: &FrameFormat, ) -> Result<(), ModelError>

pub fn insert_frame(&mut self) -> Result<Weak<Frame>, ModelError>

insert a frame at the cursor position

pub fn insert_plain_text<S: Into<String>>( &mut self, plain_text: S, ) -> Result<(usize, usize), ModelError>

Insert plain text and return (start position, end position)

pub fn selected_text(&self) -> String

pub fn text_format(&self) -> Option<TextFormat>

pub fn block_format(&self) -> Option<BlockFormat>

pub fn frame_format(&self) -> Option<FrameFormat>

pub fn remove(&mut self) -> Result<(usize, usize), ModelError>

Remove elements between two positions. Split blocks if needed. Frames in superior level (i.e. children) are completely removed even if only a part of it is selected

Return new position and number of removed chars

pub fn move_position( &mut self, move_operation: MoveOperation, move_mode: MoveMode, )

Trait Implementations

impl Clone for TextCursor

fn clone(&self) -> TextCursor

Returns a copy of the value.

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

Performs copy-assignment from source.
