Struct PlatformDrawingContext 

pub struct PlatformDrawingContext<'a> { /* private fields */ }

The drawing context core that draws straight to a platform drawing context implementation.

Implementations

impl<'a> PlatformDrawingContext<'a>

pub fn new(platform_impl: Box<dyn IDrawingContextImpl + 'a>) -> Self

Creates a core that draws to platform_impl and disposes it when the core is disposed (ownsImpl: true).

pub fn borrowed(platform_impl: &'a mut dyn IDrawingContextImpl) -> Self

Creates a core that draws to platform_impl without taking ownership of it (ownsImpl: false).

pub fn platform_impl(&mut self) -> &mut (dyn IDrawingContextImpl + 'a)

The platform drawing context implementation.

pub fn draw_rectangle_acrylic( &mut self, material: &dyn IExperimentalAcrylicMaterial, rect: RoundedRect, )

Draws a rectangle filled with an acrylic-like material. A backend without acrylic support gets the rectangle filled with the fallback color of the material.

Trait Implementations

impl IDrawingContextCore for PlatformDrawingContext<'_>

fn draw_line_core(&mut self, pen: &Rc<dyn IPen>, p1: Point, p2: Point)

Draws a line. The pen is visible.

fn draw_geometry_impl_core( &mut self, brush: Option<&Rc<dyn IBrush>>, pen: Option<&Rc<dyn IPen>>, geometry: &Arc<dyn IGeometryImpl>, )

Draws a platform geometry.

fn draw_rectangle_core( &mut self, brush: Option<&Rc<dyn IBrush>>, pen: Option<&Rc<dyn IPen>>, rrect: RoundedRect, box_shadows: &BoxShadows, )

Draws a rectangle with the specified brush and pen.

fn draw_ellipse_core( &mut self, brush: Option<&Rc<dyn IBrush>>, pen: Option<&Rc<dyn IPen>>, rect: Rect, )

Draws an ellipse with the specified brush and pen.

fn draw_bitmap( &mut self, source: &RefCounted<SharedBitmapImpl>, opacity: f64, source_rect: Rect, dest_rect: Rect, )

Draws a platform bitmap, given by a counted reference to it (upstream’s IRef<IBitmapImpl>): a context that keeps the bitmap beyond the call takes a counted reference of its own.

fn custom(&mut self, custom: &Arc<dyn ICustomDrawOperation>)

Draws a custom drawing operation.

fn draw_glyph_run( &mut self, foreground: Option<&Rc<dyn IBrush>>, glyph_run: &Rc<GlyphRun>, )

Draws a glyph run.

fn draw_rectangle_acrylic_core( &mut self, material: &dyn IExperimentalAcrylicMaterial, rect: RoundedRect, )

Draws a rectangle filled with an acrylic-like material.

fn push_clip_core(&mut self, rect: Rect)

fn push_rounded_clip_core(&mut self, rect: RoundedRect)

fn push_geometry_clip_core(&mut self, clip: &Ref<Geometry>)

fn push_opacity_core(&mut self, opacity: f64)

fn push_opacity_mask_core(&mut self, mask: &Rc<dyn IBrush>, bounds: Rect)

fn push_transform_core(&mut self, matrix: Matrix)

fn push_render_options_core(&mut self, render_options: RenderOptions)

fn push_text_options_core(&mut self, text_options: TextOptions)

fn push_effect_core(&mut self, effect: &Rc<dyn IEffect>, bounds: Rect)

fn pop_clip_core(&mut self)

fn pop_geometry_clip_core(&mut self)

fn pop_opacity_core(&mut self)

fn pop_opacity_mask_core(&mut self)

fn pop_transform_core(&mut self)

fn pop_render_options_core(&mut self)

fn pop_text_options_core(&mut self)

fn pop_effect_core(&mut self)

fn dispose_core(&mut self)

Releases the core. Called once, after every pushed state has been popped, when an owned context is disposed.

fn draw_geometry_core( &mut self, brush: Option<&Rc<dyn IBrush>>, pen: Option<&Rc<dyn IPen>>, geometry: &Ref<Geometry>, )

Draws a geometry object. The default implementation draws its platform implementation, if it has one.
