Struct slint_interpreter::ComponentDefinition

source ·
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 you’ve finished creating the instances it is safe to drop the ComponentDefinition.

Implementations§

source§

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)> + '_

Returns an iterator over all publicly declared properties. Each iterator item is a tuple of property name and property type for each of them.

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

source

pub fn type_loader(&self) -> Rc<TypeLoader>

Return the TypeLoader used when parsing the code in the interpreter.

WARNING: this is not part of the public API

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

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.
