Struct TextEditorStateInner 

pub struct TextEditorStateInner { /* private fields */ }

State structure for the text editor, managing text content, cursor, selection, and editing logic. Core text editing state, shared between components Core state for text editing, including content, selection, cursor, and interaction state.

This struct manages the text buffer, selection, cursor position, focus, and user interaction state. It is designed to be shared between UI components via a TextEditorStateHandle.

Creates a new TextEditorState 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 TextEditorState 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 text_data(&mut self, constraint: TextConstraint) -> TextData

Returns the current text buffer as TextData, applying the given layout constraints.

Arguments

• constraint - Layout constraints for text rendering.

pub fn focus_handler(&self) -> &Focus

Returns a reference to the internal focus handler.

pub fn focus_handler_mut(&mut self) -> &mut Focus

Returns a mutable reference to the internal focus handler.

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

Returns a reference to the underlying glyphon::Editor.

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

Returns a mutable reference to the underlying glyphon::Editor.

pub fn blink_timer(&self) -> Instant

Returns the current blink timer instant (for cursor blinking).

pub fn update_blink_timer(&mut self)

Resets the blink timer to the current instant.

pub fn selection_color(&self) -> Color

Returns the current selection highlight color.

pub fn current_selection_rects(&self) -> &Vec<RectDef>

Arguments

• position - The new last click position.

pub fn map_key_event_to_action( &mut self, key_event: KeyEvent, key_modifiers: ModifiersState, clipboard: &mut Clipboard, ) -> 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, navigation, and clipboard operations.

Arguments

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