Struct MarkdownEditor 

pub struct MarkdownEditor { /* private fields */ }

An Obsidian-style live-preview markdown editor. Create with cx.new(|cx| MarkdownEditor::new(cx)).

The text model is the unit-tested EditorModel (char-index cursor, anchor selection, coalesced undo); markdown structure comes from the pure block/inline/layout passes. Read-only editors render pure preview — selection, copy, and plain-click links still work.

Implementations

impl MarkdownEditor

pub fn new(cx: &mut Context<'_, Self>) -> Self

pub fn value(self, text: &str) -> Self

Initial markdown text (text() is the getter).

pub fn placeholder(self, placeholder: impl Into<SharedString>) -> Self

Dimmed hint shown while the document is empty and unfocused.

pub fn read_only(self, read_only: bool) -> Self

Render pure preview: no caret, no edits, no syntax reveal. Selection, copy, and plain-click link activation still work.

pub fn font_size(self, size: f32) -> Self

Base font size in px (default 15.0). Headings scale from it.

pub fn rows(self, rows: usize) -> Self

Minimum height, as a number of paragraph lines.

pub fn tab_size(self, n: usize) -> Self

Spaces inserted per list indent level (default 4).

pub fn style(self, style: MarkdownStyle) -> Self

Per-editor visual overrides (see MarkdownStyle).

pub fn set_style(&mut self, style: MarkdownStyle, cx: &mut Context<'_, Self>)

Replace the style at runtime (theme switches).

pub fn text(&self) -> String

The current markdown text.

pub fn set_text(&mut self, value: &str, cx: &mut Context<'_, Self>)

Replace the document, resetting cursor, selection, and history.

pub fn focus_handle(&self) -> FocusHandle

The editor’s focus handle, so a host can focus it on open.

pub fn model(&self) -> &EditorModel

Read access to the underlying EditorModel — cursor, selection, lines — for hosts building features over the buffer.

pub fn edit<R>( &mut self, cx: &mut Context<'_, Self>, f: impl FnOnce(&mut EditorModel) -> R, ) -> R

Mutate the EditorModel directly. Emits MarkdownEditorEvent::Change when the text changed, keeps the caret visible, and repaints.

pub fn bind( entity: &Entity<MarkdownEditor>, signal: &Signal<String>, cx: &mut App, )

Two-way bind this editor’s text to a Signal<String>. The signal is the source of truth; equality guards on both directions prevent update loops.

pub fn toggle_task(&mut self, line: usize, cx: &mut Context<'_, Self>) -> bool

Toggle the checkbox on line if it is a task item, preserving the cursor. Returns whether the line was a task.

impl Render for MarkdownEditor

fn render( &mut self, window: &mut Window, cx: &mut Context<'_, Self>, ) -> impl IntoElement

Render this view into an element tree.
