pub struct ComponentDefinition { /* private fields */ }
Expand description

ComponentDefinition is a representation of a compiled component from .slint markup.

It can be constructed from a .slint file using the ComponentCompiler::build_from_path or ComponentCompiler::build_from_source functions. And then it can be instantiated with the Self::create function.

The ComponentDefinition acts as a factory to create new instances. When youโ€™ve finished creating the instances it is safe to drop the ComponentDefinition.

Implementationsยง

sourceยง

impl ComponentDefinition

source

pub fn create(&self) -> Result<ComponentInstance, PlatformError>

Creates a new instance of the component and returns a shared handle to it.

source

pub fn properties(&self) -> impl Iterator<Item = (String, ValueType)> + '_

List of publicly declared properties.

source

pub fn callbacks(&self) -> impl Iterator<Item = String> + '_

Returns the names of all publicly declared callbacks.

source

pub fn globals(&self) -> impl Iterator<Item = String> + '_

Returns the names of all exported global singletons

Note: Only globals that are exported or re-exported from the main .slint file will be exposed in the API

source

pub fn global_properties( &self, global_name: &str ) -> Option<impl Iterator<Item = (String, ValueType)> + '_>

List of publicly declared properties in the exported global singleton specified by its name.

source

pub fn global_callbacks( &self, global_name: &str ) -> Option<impl Iterator<Item = String> + '_>

List of publicly declared callbacks in the exported global singleton specified by its name.

source

pub fn name(&self) -> &str

The name of this Component as written in the .slint file

impl<T> Downcast for Twhere T: Any,

ยง

fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
ยง

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
ยง

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Anyโ€™s vtable from &Traitโ€™s.
ยง

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Anyโ€™s vtable from &mut Traitโ€™s.
