Struct IMContext 

pub struct IMContext { /* private fields */ }

GtkIMContext * im_module_create(const gchar *context_id); ]| This function should return a pointer to a newly created instance of the IMContext subclass identified by context_id. The context ID is the same as specified in the GtkIMContextInfo array returned by im_module_list().

After a new loadable input method module has been installed on the system, the configuration file gtk.immodules needs to be regenerated by [gtk-query-immodules-3.0][gtk-query-immodules-3.0], in order for the new input method to become available to GTK+ applications.

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

Signals

commit

The ::commit signal is 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

The ::delete-surrounding signal is emitted when the input method needs to delete all or part of the context surrounding the cursor.

preedit-changed

The ::preedit-changed signal is emitted whenever the preedit sequence currently being entered has changed. It is also emitted at the end of a preedit sequence, in which case IMContextExt::preedit_string() returns the empty string.

preedit-end

The ::preedit-end signal is emitted when a preediting sequence has been completed or canceled.

preedit-start

The ::preedit-start signal is emitted when a new preediting sequence starts.

retrieve-surrounding

The ::retrieve-surrounding signal is emitted when the input method requires the context surrounding the cursor. The callback should set the input method surrounding context by calling the IMContextExt::set_surrounding() method.

Implements

IMContextExt, [trait@glib::ObjectExt]

GLib type: GObject with reference counted clone semantics.

Implementations

impl IMContext

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

Trait Implementations

impl Clone for IMContext

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 IMContext

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

Formats the value using the given formatter.

impl Eq for IMContext

impl HasParamSpec for IMContext

type ParamSpec = ParamSpecObject

type SetValue = IMContext

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for IMContext

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 IsA<IMContext> for IMContextSimple

impl IsA<IMContext> for IMMulticontext

impl Ord for IMContext

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 IMContext

type Parent = Object

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

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

Inequality operator !=.

impl<OT: ObjectType> PartialOrd<OT> for IMContext

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 IMContext

fn static_type() -> Type

Returns the type identifier of Self.
