Struct gtk4::IMMulticontext
source · pub struct IMMulticontext { /* private fields */ }
Expand description
IMMulticontext
is an input method context supporting multiple,
switchable input methods.
Text widgets such as Text
or TextView
use a GtkIMMultiContext
to implement their im-module
property for switching between different
input methods.
§Implements
IMMulticontextExt
, IMContextExt
, [trait@glib::ObjectExt

pub const NONE: Option<&'static IMMulticontext> = None
sourcepub fn new() -> IMMulticontext
pub fn new() -> IMMulticontext
sourcepub fn builder() -> IMMulticontextBuilder
pub fn builder() -> IMMulticontextBuilder
Creates a new builder-pattern struct instance to construct IMMulticontext
objects.
This method returns an instance of IMMulticontextBuilder
which can be used to create IMMulticontext
objects.
