Struct InputMethodContext 

pub struct InputMethodContext { /* private fields */ }

Base class for input method contexts.

WebKitInputMethodContext defines the interface to implement WebKit input methods. The input methods are used by WebKit, when editable content is focused, to map from key events to Unicode character strings.

An input method may consume multiple key events in sequence and finally output the composed result. This is called preediting, and an input method may provide feedback about this process by displaying the intermediate composition states as preedit text.

This is an Abstract Base Class, you cannot instantiate it.

Properties

input-hints

The #WebKitInputHints of the input associated with this context.

Readable | Writeable

input-purpose

The #WebKitInputPurpose of the input associated with this context.

Readable | Writeable

Signals

committed

Emitted when a complete input sequence has been entered by the user. This can be a single character immediately after a key press or the final result of preediting.

delete-surrounding

Emitted when the input method wants to delete the context surrounding the cursor. If @offset is a negative value, it means a position before the cursor.

preedit-changed

Emitted whenever the preedit sequence currently being entered has changed. It is also emitted at the end of a preedit sequence, in which case webkit_input_method_context_get_preedit() returns the empty string.

preedit-finished

Emitted when a preediting sequence has been completed or canceled.

preedit-started

Emitted when a new preediting sequence starts.

Implements

InputMethodContextExt

GLib type: GObject with reference counted clone semantics.

Implementations

impl InputMethodContext

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

Trait Implementations

impl Clone for InputMethodContext

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 InputMethodContext

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

Formats the value using the given formatter.

impl HasParamSpec for InputMethodContext

type ParamSpec = ParamSpecObject

type SetValue = InputMethodContext

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for InputMethodContext

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 InputMethodContext

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 InputMethodContext

type Parent = Object

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

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 InputMethodContext

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 InputMethodContext

fn static_type() -> Type

Returns the type identifier of Self.
