Required Methods§

source

fn render( self, layout_node: &LayoutNode, node_ref: &NodeRef<'_, CustomAttributeValues>, canvas: &Canvas, font_collection: &mut RCHandle<skia_textlayout_FontCollection>, font_manager: &RCHandle<SkFontMgr>, default_fonts: &[String], scale_factor: f32, )

Provided Methods§

source

fn is_point_inside_area( &self, point: &Point2D<f64, Measure>, _node_ref: &NodeRef<'_, CustomAttributeValues>, layout_node: &LayoutNode, _scale_factor: f32, ) -> bool

source

fn clip( &self, _layout_node: &LayoutNode, _node_ref: &NodeRef<'_, CustomAttributeValues>, _canvas: &Canvas, _scale_factor: f32, )

source

fn element_drawing_area( &self, layout_node: &LayoutNode, _node_ref: &NodeRef<'_, CustomAttributeValues>, _scale_factor: f32, ) -> Rect<f32, Measure>

source

fn drawing_area_with_viewports( &self, layout_node: &LayoutNode, node_ref: &NodeRef<'_, CustomAttributeValues>, layout: &Torin<EntityId>, scale_factor: f32, ) -> Option<Rect<f32, Measure>>

source

fn drawing_area( &self, layout_node: &LayoutNode, node_ref: &NodeRef<'_, CustomAttributeValues>, scale_factor: f32, ) -> Rect<f32, Measure>

Measure the area for this element considering other factors like shadows or borders, which are not part of the layout.

source

fn element_needs_cached_area( &self, _node_ref: &NodeRef<'_, CustomAttributeValues>, ) -> bool

Check if this element requires any kind of special caching. Mainly used for text-like elements with shadows. See [crate::compositor::CompositorCache]. Default to false.

fn needs_cached_area( &self, node_ref: &NodeRef<'_, CustomAttributeValues>, ) -> bool
