Implementations

impl CodeEditor

pub fn update(&mut self, message: &Message) -> Task<Message>

Updates the editor state based on messages and returns scroll commands.

Arguments

• message - The message to process

Returns

A Task that may contain scroll commands to keep cursor visible

impl CodeEditor

pub fn view(&self) -> Element<'_, Message>

Creates the view element with scrollable wrapper.

impl CodeEditor

pub fn new(content: &str, syntax: &str) -> Self

Creates a new canvas-based text editor.

Arguments

• content - Initial text content
• syntax - Syntax highlighting language (e.g., “py”, “lua”, “rs”)

Returns

A new CodeEditor instance

pub fn content(&self) -> String

Returns the current text content as a string.

Returns

The complete text content of the editor

pub fn with_viewport_height(self, height: f32) -> Self

Sets the viewport height for the editor.

This determines the minimum height of the canvas, ensuring proper background rendering even when content is smaller than the viewport.

Arguments

• height - The viewport height in pixels

Returns

Self for method chaining

Example

use iced_code_editor::CodeEditor;

let editor = CodeEditor::new("fn main() {}", "rs")
    .with_viewport_height(500.0);

pub fn set_theme(&mut self, style: Style)

Sets the theme style for the editor.

Arguments

• style - The style to apply to the editor

Example

use iced_code_editor::{CodeEditor, theme};

let mut editor = CodeEditor::new("fn main() {}", "rs");
editor.set_theme(theme::light(&iced::Theme::Light));

pub fn is_modified(&self) -> bool

Returns whether the editor has unsaved changes.

Returns

true if there are unsaved modifications, false otherwise

pub fn mark_saved(&mut self)

Marks the current state as saved.

Call this after successfully saving the file to reset the modified state.

pub fn can_undo(&self) -> bool

Returns whether undo is available.

pub fn can_redo(&self) -> bool

Returns whether redo is available.
