Trait Implementations

impl InputModeKind for TextareaMode

type Extras = ()

Ordinary multi-line text needs nothing beyond the shared engine.

const MULTI_LINE: bool = true

Whether this kind of input spans more than one line.

const CODE_EDITOR: bool = false

Whether this kind of input is a source-code editor.

fn drive_highlighter( _highlighter: &Rc<RefCell<Option<Box<dyn InputHighlighter>>>>, _edit: InputEdit, _text: &Rope, _folding: bool, _window: &mut Window, _cx: &mut Context<'_, InputBaseState<Self>>, )

Drives the syntax highlighter after the text changed.

fn hover_definition_style( _state: &InputBaseState<Self>, _cx: &App, ) -> Option<(Range<usize>, HighlightStyle)>

The range highlighted while Cmd-hovering a symbol, with its style.

fn hover_definition_hitbox( _state: &InputBaseState<Self>, _window: &mut Window, _cx: &App, ) -> Option<Hitbox>

The hitbox for Cmd-hover, when the mode supports go-to-definition.

fn reset_language_features(_state: &mut InputBaseState<Self>)

Drops cached language-server results, e.g. after the text is replaced.

fn reset_annotations(_state: &mut InputBaseState<Self>)

Drops decorations and hover state when the text is replaced wholesale.

fn adjust_annotations( _state: &mut InputBaseState<Self>, _range: &Range<usize>, _new_len: usize, )

Slides decoration ranges along with an edit.

fn refresh_language_features( _state: &mut InputBaseState<Self>, _window: &mut Window, _cx: &mut Context<'_, InputBaseState<Self>>, )

Refreshes language-server state after the text changed.

fn accept_inline_completion( _state: &mut InputBaseState<Self>, _window: &mut Window, _cx: &mut Context<'_, InputBaseState<Self>>, ) -> bool

Takes the pending inline completion, when Tab should accept it.

fn has_inline_completion(_state: &InputBaseState<Self>) -> bool

Whether an inline completion is waiting to be accepted.

fn on_click( _state: &mut InputBaseState<Self>, _event: &MouseDownEvent, _offset: usize, _window: &mut Window, _cx: &mut Context<'_, InputBaseState<Self>>, ) -> bool

Reacts to a click, for Cmd-click go-to-definition.

fn clear_hover_state( _state: &mut InputBaseState<Self>, _cx: &mut Context<'_, InputBaseState<Self>>, )

Drops hover state when the pointer leaves or focus moves.

fn on_text_typed( _state: &mut InputBaseState<Self>, _range: &Range<usize>, _text: &str, _window: &mut Window, _cx: &mut Context<'_, InputBaseState<Self>>, )

Offers freshly typed text to the completion engine.

fn clear_inline_completion( _state: &mut InputBaseState<Self>, _cx: &mut Context<'_, InputBaseState<Self>>, )

Drops any inline completion after the text or cursor moved.

fn hide_context_menu( _state: &mut InputBaseState<Self>, _cx: &mut Context<'_, InputBaseState<Self>>, )

Closes any open completion or code-action menu.

fn is_context_menu_open(_state: &InputBaseState<Self>, _cx: &App) -> bool

Whether a completion or code-action menu is currently open.

fn handle_context_menu_action( _state: &mut InputBaseState<Self>, _action: Box<dyn Action>, _window: &mut Window, _cx: &mut Context<'_, InputBaseState<Self>>, ) -> bool

Lets an open menu consume the action first. Returns true when it did.

fn on_hover_definition( _state: &mut InputBaseState<Self>, _offset: usize, _window: &mut Window, _cx: &mut Context<'_, InputBaseState<Self>>, )

Highlights the symbol under the pointer for go-to-definition.

fn on_mouse_move( _state: &mut InputBaseState<Self>, _offset: usize, _event: &MouseMoveEvent, _window: &mut Window, _cx: &mut Context<'_, InputBaseState<Self>>, )

Reacts to the pointer moving, for the hover popover.

fn register_actions( element: Stateful<Div>, _entity: &Entity<InputBaseState<Self>>, _window: &mut Window, ) -> Stateful<Div>

Registers the actions that only this mode handles.
