Struct TextEditor 

pub struct TextEditor { /* private fields */ }

Text editor with cursor and selection management.

Implementations

impl TextEditor

pub fn new(text: impl Into<String>) -> Self

Create a new text editor with initial text.

pub fn text(&self) -> &str

Get the current text content.

pub fn cursor(&self) -> &TextCursor

Get the cursor position.

pub fn selection(&self) -> Option<&TextSelection>

Get the selection, if any.

pub fn has_selection(&self) -> bool

Check if there’s an active selection.

pub fn set_cursor(&mut self, position: usize)

Set the cursor position (byte offset).

pub fn move_cursor_start(&mut self)

Move cursor to start of text.

pub fn move_cursor_end(&mut self)

Move cursor to end of text.

pub fn move_cursor_left(&mut self)

Move cursor left by one character.

pub fn move_cursor_right(&mut self)

Move cursor right by one character.

pub fn select(&mut self, start: usize, end: usize)

Select text range.

pub fn select_all(&mut self)

Select all text.

pub fn clear_selection(&mut self)

Clear selection.

pub fn insert_char(&mut self, c: char)

Insert a character at the cursor position.

pub fn insert_str(&mut self, s: &str)

Insert a string at the cursor position.

pub fn delete_char(&mut self)

Delete character before cursor (backspace).

pub fn delete_char_forward(&mut self)

Delete character after cursor (delete key).

pub fn delete_selection(&mut self)

Delete the current selection.

pub fn selected_text(&self) -> Option<&str>

Get selected text.

pub fn replace_selection(&mut self, text: &str)

Replace selected text with new text.

pub fn undo(&mut self) -> bool

Undo last operation.

pub fn redo(&mut self) -> bool

Redo last undone operation.

pub fn hit_test(&self, _pos: Vec2, _char_width: f32) -> usize

Hit test to find cursor position from screen coordinates.

This is a simplified version that assumes monospace font. For real usage, you’d need glyph position information from the text shaper.

pub fn selection_rects( &self, _line_height: f32, _char_width: f32, ) -> Vec<(f32, f32, f32, f32)>

Get selection rectangles for rendering.

This is a simplified version that returns a single rectangle. For real usage with multi-line selections, you’d need line layout information.
