Struct IMContextSimple

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.

Implements

IMContextExt, [trait@glib::ObjectExt]

GLib type: GObject with reference counted clone semantics.

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

Creates a new builder-pattern struct instance to construct IMContextSimple objects.

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

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

fn clone_from(&mut self, source: &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 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,

Hashes the memory address of this object.

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

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl ParentClassIs for IMContextSimple

type Parent = IMContext

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

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

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

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<OT: ObjectType> PartialOrd<OT> for IMContextSimple

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

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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.
