Struct ComponentFactory

pub struct ComponentFactory(/* private fields */);

A ComponentFactory can be used to create new Components at runtime, taking a factory function returning a ComponentHandle.

The FactoryContext is passed to that factory function.

A ComponentFactory implements the component-factory type for properties in the Slint language.

The component-factory is used by an ComponentContainer element in Slint files to embed UI elements based on the produced component within the ComponentContainer element.

Implementations

impl ComponentFactory

pub fn new<T: ComponentHandle + 'static>( factory: impl Fn(FactoryContext) -> Option<T> + 'static, ) -> Self

where T::Inner: HasStaticVTable<ItemTreeVTable> + 'static,

Create a new ComponentFactory

Trait Implementations

impl Clone for ComponentFactory

fn clone(&self) -> ComponentFactory

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ComponentFactory

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

Formats the value using the given formatter.

impl Default for ComponentFactory

fn default() -> ComponentFactory

Returns the “default value” for a type.

impl PartialEq for ComponentFactory

fn eq(&self, other: &ComponentFactory) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
