Implementations

impl TextEditorController

pub fn new(size: Dp, line_height: Option<Dp>) -> Self

Creates a new TextEditorController with the given font size and optional line height.

Arguments

• size - Font size in Dp.
• line_height - Optional line height in Dp. If None, uses 1.2x the font size.

pub fn with_selection_color( size: Dp, line_height: Option<Dp>, selection_color: Color, ) -> Self

Creates a new TextEditorController with a custom selection highlight color.

Arguments

• size - Font size in Dp.
• line_height - Optional line height in Dp.
• selection_color - Color used for selection highlight.

pub fn line_height(&self) -> Px

Returns the line height in pixels.

pub fn request_focus(&self)

Requests keyboard focus for this editor while it is attached and available.

Hidden or disabled editors reject the request. A scrollable ancestor may reveal an attached editor that is outside its viewport.

pub fn editor(&self) -> &Editor<'static>

Returns a reference to the underlying glyphon::Editor.

pub fn with_editor_mut<F, R>(&mut self, f: F) -> R

where F: FnOnce(&mut Editor<'static>) -> R,

Mutates the underlying glyphon::Editor and refreshes layout state.

pub fn selection_color(&self) -> Color

Returns the current selection highlight color.

pub fn set_selection_color(&mut self, color: Color)

Sets the selection highlight color.

Arguments

• color - The new selection color.

pub fn text_color(&self) -> Color

Returns the current text color.

pub fn set_text_color(&mut self, color: Color)

Sets the text color used by the editor.

pub fn text_style(&self) -> TextStyle

Returns the typography used by editable text.

pub fn set_text_style(&mut self, style: TextStyle)

Sets typography while preserving text and selection.

pub fn cursor_color(&self) -> Color

Returns the cursor color.

pub fn set_cursor_color(&mut self, color: Color)

Sets the cursor color used by the editor.

pub fn set_display_transform(&mut self, transform: Option<DisplayTransform>)

Sets a display transform applied when rendering text.

pub fn display_transform_active(&self) -> bool

Returns whether a display transform is active.

pub fn is_dragging(&self) -> bool

Returns true if a drag operation is in progress.

pub fn map_key_event_to_action( &mut self, key_event: KeyboardEvent, key_modifiers: ModifiersState, ) -> Option<Vec<Action>>

Map keyboard events to text editing actions Maps a keyboard event to a list of text editing actions for the editor.

This function translates keyboard input (including modifiers) into editing actions such as character insertion, deletion, and navigation.

Clipboard shortcuts are handled at a higher layer so they stay on the unified edit pipeline instead of bypassing controller state.

Arguments

• key_event - The keyboard event to map.
• key_modifiers - The current keyboard modifier state.

Returns

An optional vector of glyphon::Action to be applied to the editor.

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