Struct ServerShapeVisual 

pub struct ServerShapeVisual { /* private fields */ }

Server-side counterpart of a ShapeVisual: its shapes, through its view box, clipped to its size, then its children.

The visual observes its shape collection and its view box, which are render resources: a change of either, or of anything a shape shows (an animation included), redraws it.

Implementations

impl ServerShapeVisual

pub fn new() -> Self

pub fn props(&self) -> &ServerShapeVisualProps

The properties of the visual.

pub fn shapes(&self) -> Vec<Rc<dyn IServerObject>>

The shapes, in drawing order.

pub fn view_box_mapping(&self, size: Vector) -> Option<ViewBoxMapping>

How the view box maps the shapes onto a visual of size, when the visual has a view box that maps anything.

Trait Implementations

impl Default for ServerShapeVisual

fn default() -> Self

Returns the “default value” for a type.

impl IServerVisualContent for ServerShapeVisual

fn compute_own_content_bounds( &self, visual: &ServerCompositionVisual, ) -> Option<LtrbRect>

The size of the visual: the shapes are clipped to it.

fn render_core( &self, visual: &ServerCompositionVisual, context: &mut ServerVisualRenderContext<'_>, _current_transformed_clip: LtrbRect, )

Draws the shapes in order, clipped to the size of the visual and to the mapped view box.

Deviation (winui-composition.md): the shapes are clipped to the size of the visual (a shape visual without a size shows nothing, as in WinUI) and to the view box (the port’s reading of WinUI).

fn dependency_queued_invalidate(&self, visual: &ServerCompositionVisual)

The shape collection or the view box changed.

fn deserialize_changes_core( &self, visual: &ServerCompositionVisual, reader: &mut BatchStreamReader<'_>, committed_at: Duration, )

DeserializeChangesCore of the class; the default is the one of the container visual.

fn size_changed(&self, visual: &ServerCompositionVisual)

fn dispose(&self, visual: &ServerCompositionVisual)

The visual has been disposed on the UI thread.

fn find_props(&self, type_id: TypeId) -> Option<&dyn Any>

The generated property block of the given type, if the class has one of its own.

fn get_composition_property( &self, name: &str, ) -> Option<&'static CompositionProperty>

fn as_any(&self) -> &dyn Any

fn on_attached_to_root( &self, _visual: &ServerCompositionVisual, _target: &Rc<ServerCompositionTarget>, )

fn on_detached_from_root( &self, _visual: &ServerCompositionVisual, _target: &Rc<ServerCompositionTarget>, )

fn push_clip_to_bounds( &self, visual: &ServerCompositionVisual, canvas: &mut dyn IDrawingContextImpl, )

fn has_effect(&self, visual: &ServerCompositionVisual) -> bool

fn render_after_children( &self, _visual: &ServerCompositionVisual, _context: &mut ServerVisualRenderContext<'_>, )

Called by the render walk after the children of the visual were rendered, before the opacity mask, effect, clips and transform of the visual are popped: what render_core pushed for the children is popped here (not from upstream; the layer of a layer visual).

fn sub_tree_bounds_padding( &self, _visual: &ServerCompositionVisual, ) -> Option<Thickness>

What the content adds around the bounds of the subtree, like the output padding of an effect (not from upstream; the shadow of a layer visual). None for nothing.

fn has_update_pass_content_bounds(&self) -> bool

Whether the bounds of the own content depend on other visuals and are computed again when the update pass of the target reaches the visual (not from upstream; a redirect visual covers the bounds of its source as that pass leaves them).
