Implementations

impl BaseInstance

pub fn new(args: InstantiationArgs, flags: InstanceFlags) -> Self

Build shared instance state from compiler-generated instantiation args.

pub fn get_handler_registry(&self) -> Option<Rc<RefCell<HandlerRegistry>>>

Returns a handle to a node-managed HandlerRegistry, a mapping between event types and handlers. Each node that can handle events is responsible for implementing this; Component instances generate the necessary code to wire up userland events like <SomeNode @click=self.handler>. Primitives must handle this explicitly, see e.g. [pax_std::drawing::rectangle::RectangleInstance#get_handler_registry].

pub fn get_instance_children(&self) -> &InstanceNodePtrList

Return the list of instance nodes that are children of this one. Intuitively, this returns the nodes owned directly by this instance’s definition.

For Components, this returns the root(s) of the component template, not the projected children supplied by the containing component.

pub fn flags(&self) -> &InstanceFlags

Static behavior flags for this instance.

pub fn transition_config(&self) -> &ComponentTransitionConfig
