Implementations

impl<R: 'static + RenderContext> PaxEngine<R>

pub fn new( main_component_instance: Rc<RefCell<ComponentInstance<R>>>, expression_table: HashMap<usize, Box<dyn Fn(ExpressionContext<'_, R>) -> TypesCoproduct>>, logger: PlatformSpecificLogger, viewport_size: (f64, f64), instance_registry: Rc<RefCell<InstanceRegistry<R>>> ) -> Self

pub fn get_topmost_element_beneath_ray( &self, ray: (f64, f64) ) -> Option<Rc<RepeatExpandedNode<R>>>

Simple 2D raycasting: the coordinates of the ray represent a ray running orthogonally to the view plane, intersecting at the specified point ray. Areas outside of clipping bounds will not register a hit, nor will elements that suppress input events.

pub fn get_focused_element(&self) -> Option<Rc<RepeatExpandedNode<R>>>

pub fn set_viewport_size(&mut self, new_viewport_size: (f64, f64))

Called by chassis when viewport size changes, e.g. with native window resizes

pub fn tick(&mut self, rcs: &mut HashMap<String, R>) -> Vec<NativeMessage>

Workhorse method to advance rendering and property calculation by one discrete tick Will be executed synchronously up to 240 times/second.

pub fn load_image( &mut self, id_chain: Vec<u32>, image_data: Vec<u8>, width: usize, height: usize )
