Expand description

What a concrete server visual class adds to ServerCompositionVisual: its own properties and its overrides of the virtual members.

Required Methods§

Source

fn as_any(&self) -> &dyn Any

Provided Methods§

Source

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.

Source

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

Source

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

Source

fn size_changed(&self, _visual: &ServerCompositionVisual)

Source

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

Source

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

Source

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

Source

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

Source

fn dependency_queued_invalidate(&self, _visual: &ServerCompositionVisual)

A render resource the content depends on changed.

Source

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).

Source

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.

Source

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).

Source

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.

Source

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

Source

fn dispose(&self, _visual: &ServerCompositionVisual)

The visual has been disposed on the UI thread.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
