Struct TextArea 

pub struct TextArea { /* private fields */ }

A multi-line editable text area bound to a RwSignal<String> — the multi-line sibling of Input. A base primitive: unstyled (wrap it in a box for a border/background), keyboard-driven, no soft-wrap (only \n breaks lines, so long lines overflow horizontally). It requests focus on tap, positions the caret at the click, edits the bound signal from key events (typing, Enter for a newline, Backspace/Delete joining lines, arrows in all four directions, Home/End, Tab), and draws a caret. Its measured height grows with the line count, so wrapping it in a LayoutScrollArea gives a scrolling editor. Selection (Shift+arrows, Ctrl+A, shift-click) with copy, cut and paste, newlines and all. IME is not yet supported.

Implementations

impl TextArea

pub fn new( value: RwSignal<String>, layout_style: LayoutStyle, style_fn: impl Fn() -> TextStyle + 'static, ) -> Result<TextArea, LayoutError>

pub fn placeholder(self, p: impl Into<String>) -> TextArea

A muted hint shown while the value is empty.

pub fn request_focus(&self)

Gives keyboard focus to this area (as a tap would), leaving the caret where it was. For programmatic focus — e.g. a container autofocusing the editor when its tab or window becomes active.

pub fn focused(&self) -> bool

Whether this area currently holds keyboard focus.

pub fn focus_handle(&self) -> FocusHandle

A Copy focus::FocusHandle to this area, so a caller that has moved it into a container can still focus it later (e.g. autofocus on tab activation) without keeping a reference to the area itself.

Trait Implementations

impl Component for TextArea

fn view(&self) -> RenderNode

fn on_event(&mut self, event: &Event) -> EventResult

fn debug_name(&self) -> &'static str

Human-readable widget type name for the devtools tree inspector.

impl Drop for TextArea

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
