Struct ServerCompositionEllipseGeometry 

pub struct ServerCompositionEllipseGeometry { /* private fields */ }

The server-side counterpart of a CompositionEllipseGeometry.

Implementations

impl ServerCompositionEllipseGeometry

pub fn new( compositor: &Rc<ServerCompositor>, ) -> Rc<ServerCompositionEllipseGeometry>

Creates the geometry, active: the UI-thread geometry activates its server object when it is created.

pub fn props(&self) -> &ServerCompositionEllipseGeometryProps

The properties of the geometry.

pub fn is_disposed(&self) -> bool

impl ServerCompositionEllipseGeometry

pub fn rect(&self) -> Rect

The bounds of the ellipse.

Trait Implementations

impl IAnimatedServerObject for ServerCompositionEllipseGeometry

fn server_object(&self) -> &ServerObject

The embedded ServerObject part.

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

The composition property with the given name, if the class has one.

fn as_server_object_dyn(&self) -> &dyn IServerObject

The object as the base contract (an explicit upcast).

fn read_property_variant( &self, property: &'static CompositionProperty, ) -> ExpressionVariant

Reads a property of the object as a variant. The default reads the field through CompositionProperty::get_variant; an object with dynamic properties (a property set) reads its own storage.

fn write_property_variant( &self, property: &'static CompositionProperty, value: ExpressionVariant, )

Writes a variant into a property of the object without notification (what an animation does with the value it evaluated). The default writes the field through CompositionProperty::set_variant; an object with dynamic properties writes its own storage.

impl IServerAnimatedPropertyHost for ServerCompositionEllipseGeometry

fn set_animated_value( &self, property: &'static CompositionProperty, current_value: ExpressionVariant, committed_at: Duration, animation: Rc<dyn IAnimationInstance>, )

SetAnimatedValue(prop, ref field, committedAt, animation): starts animation on the property. current_value is the value of the field as a variant; the animation writes the field through CompositionProperty::set_variant.

fn remove_animation_for_property(&self, property: &'static CompositionProperty)

The tail of SetAnimatedValue(prop, out field, value): the field has been assigned directly, so the animation of the property, if any, is removed.

fn notify_animated_value_changed(&self, _property: &'static CompositionProperty)

An animation wrote a new value into the field of property.

impl IServerCompositionGeometry for ServerCompositionEllipseGeometry

fn platform_geometry(&self) -> Option<Arc<dyn IGeometryImpl>>

The platform geometry with the trimming applied, cached until a member of the geometry changes. None when there is nothing to draw (no path, or a trim that leaves nothing) or when the compositor has no render interface.

fn geometry_props(&self) -> &ServerCompositionGeometryProps

The properties of CompositionGeometry (the trimming).

impl IServerObject for ServerCompositionEllipseGeometry

fn values_invalidated(&self)

A member changed (directly or by an animation): the geometry is built again when it is next drawn.

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

Reads the changes of the object from a batch.

fn dispose(&self)

Releases the object: it has been disposed on the UI thread.

fn as_render_resource(self: Rc<Self>) -> Option<Rc<dyn IServerRenderResource>>

The object as a render resource, if it is one.

fn as_animated(self: Rc<Self>) -> Option<Rc<dyn IAnimatedServerObject>>

The object as an animatable object, if it is one.

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

The generated property block of the given type embedded in the object, if it has one. A class that embeds generated properties forwards to their find_props; composition properties locate their fields through it.

fn as_any(&self) -> &dyn Any

fn into_any_rc(self: Rc<Self>) -> Rc<dyn Any>

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

Applies the changes of the object from a batch.

fn as_brush(self: Rc<Self>) -> Option<Rc<dyn IBrush>>

The object as a brush, if it is a server-side brush.

fn as_pen(self: Rc<Self>) -> Option<Rc<dyn IPen>>

The object as a pen, if it is a server-side pen.

fn as_render_data_geometry( self: Rc<Self>, ) -> Option<Rc<dyn IRenderDataGeometry>>

The object as a geometry usable by render data, if it is a server-side geometry.

fn as_transform(self: Rc<Self>) -> Option<Rc<dyn ITransform>>

The object as a transform, if it is a server-side transform.

fn as_gradient_stop(self: Rc<Self>) -> Option<Rc<dyn IGradientStop>>

The object as a gradient stop, if it is a server-side gradient stop.

fn as_surface(self: Rc<Self>) -> Option<Rc<dyn IServerCompositionSurface>>

The object as a composition surface, if it is one.

impl IServerPropertyHost for ServerCompositionEllipseGeometry

fn server_compositor(&self) -> Option<Rc<ServerCompositor>>

The compositor of the object, while it is alive. Used to resolve the server objects a batch refers to.

fn set_value( &self, _property: &'static CompositionProperty, change: ServerValueChange<'_>, )

SetValue(prop, ref field, value) as the class of the object defines it. A plain server object assigns; an animated object also invalidates the subscriptions of the property; a render resource goes through super::ServerRenderResourceCore::set_value.

impl IServerRenderResource for ServerCompositionEllipseGeometry

fn add_observer(&self, observer: &Rc<dyn IServerRenderResourceObserver>)

fn remove_observer(&self, observer: &Rc<dyn IServerRenderResourceObserver>)

fn queued_invalidate(&self)

impl IServerRenderResourceHost for ServerCompositionEllipseGeometry

fn compositor(&self) -> Option<Rc<ServerCompositor>>

The compositor of the resource, while it is alive.

fn as_render_resource_rc(&self) -> Option<Rc<dyn IServerRenderResource>>

The resource as a shared handle, for the invalidation queue.

fn resource_property_changed(&self)

Called once per group of property changes, before the queued invalidation.

impl IServerRenderResourceObserver for ServerCompositionEllipseGeometry

fn dependency_queued_invalidate(&self, _sender: &dyn IServerRenderResource)

impl ServerCompositionEllipseGeometryHooks for ServerCompositionEllipseGeometry

fn deserialize_changes_extra(&self, _reader: &mut BatchStreamReader<'_>)

fn on_fields_deserialized( &self, _changed: CompositionEllipseGeometryChangedFields, )

impl ServerCompositionGeometryHooks for ServerCompositionEllipseGeometry

fn deserialize_changes_extra(&self, _reader: &mut BatchStreamReader<'_>)

fn on_fields_deserialized(&self, _changed: CompositionGeometryChangedFields)
