Struct gtk4::IMContextSimple

#[repr(transparent)]
pub struct IMContextSimple { /* private fields */ }

IMContextSimple is an input method supporting table-based input methods.

Compose sequences

IMContextSimple reads compose sequences from the first of the following files that is found: ~/.config/gtk-4.0/Compose, ~/.XCompose, /usr/share/X11/locale/$locale/Compose (for locales that have a nontrivial Compose file). A subset of the file syntax described in the Compose(5) manual page is supported. Additionally, include "L" loads GTK’s built-in table of compose sequences rather than the locale-specific one from X11.

If none of these files is found, IMContextSimple uses a built-in table of compose sequences that is derived from the X11 Compose files.

Note that compose sequences typically start with the Compose_key, which is often not available as a dedicated key on keyboards. Keyboard layouts may map this keysym to other keys, such as the right Control key.

Unicode characters

IMContextSimple also supports numeric entry of Unicode characters by typing Ctrl-Shift-u, followed by a hexadecimal Unicode codepoint.

For example,

Ctrl-Shift-u 1 2 3 Enter

yields U+0123 LATIN SMALL LETTER G WITH CEDILLA, i.e. ģ.

Dead keys

IMContextSimple supports dead keys. For example, typing

dead_acute a

yields U+00E! LATIN SMALL LETTER_A WITH ACUTE, i.e. á. Note that this depends on the keyboard layout including dead keys.

Implementations

impl IMContextSimple

pub const NONE: Option<&'static IMContextSimple> = None

pub fn new() -> IMContextSimple

Creates a new IMContextSimple.

Returns

a new IMContextSimple

pub fn builder() -> IMContextSimpleBuilder

This method returns an instance of IMContextSimpleBuilder which can be used to create IMContextSimple objects.

impl IMContextSimple

pub fn add_compose_file(&self, compose_file: impl AsRef<Path>)

Trait Implementations

impl Clone for IMContextSimple

fn clone(&self) -> Self

Performs copy-assignment from source.

impl Debug for IMContextSimple

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

Formats the value using the given formatter.

impl Default for IMContextSimple

fn default() -> Self

Returns the “default value” for a type.

impl Display for IMContextSimple

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

Formats the value using the given formatter.

impl HasParamSpec for IMContextSimple

type ParamSpec = ParamSpecObject

type SetValue = IMContextSimple

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, IMContextSimple>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for IMContextSimple

fn hash<H>(&self, state: &mut H)where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for IMContextSimple

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

impl ParentClassIs for IMContextSimple

type Parent = IMContext

impl<OT: ObjectType> PartialEq<OT> for IMContextSimple

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

This method tests for self and other values to be equal, and is used by ==.

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

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

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for IMContextSimple

fn static_type() -> Type

Returns the type identifier of Self.
