Struct ImeComposition 

pub struct ImeComposition {
    pub active_underline_stroke: Stroke,
    pub inactive_underline_stroke: Stroke,
    pub legacy_visuals: bool,
}

Visual style for IME composition.

Fields

active_underline_stroke: Stroke

Stroke used to underline the actively composed segment.

inactive_underline_stroke: Stroke

Stroke used to underline those non-active segments.

legacy_visuals: bool

If true, IME (Input Method Editor) composition (preedit) text is rendered the legacy way: visually indistinguishable from a text selection, with the cursor always shown at the end of the composition.

If false, egui renders proper IME composition visuals: the cursor position inside the composition is shown, and the active conversion segment is highlighted (using the strokes configured above) distinctly from the rest of the composition. This makes composing Chinese, Japanese and Korean text much clearer.

The legacy visuals have known shortcomings, but the new visuals are not yet fully reliable on every platform either (e.g. winit reports an incorrect cursor position for Korean IMEs on Windows), so this remains configurable.

Defaults to true on Windows (because of the aforementioned winit bug) and to false everywhere else.

Implementations

impl ImeComposition

pub fn ui(&mut self, ui: &mut Ui)

Trait Implementations

impl Clone for ImeComposition

fn clone(&self) -> ImeComposition

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ImeComposition

impl Debug for ImeComposition

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ImeComposition

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ImeComposition

where ImeComposition: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ImeComposition

fn eq(&self, other: &ImeComposition) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ImeComposition

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
