AView::render
virtual void render(ARenderContext ctx)
Draws this AView. Noone should call this function except rendering routine.

IRenderer::lines
virtual void lines(const ABrush &brush, AArrayView< glm::vec2 > points, const ABorderStyle &style, AMetric width)=0
Draws polyline (non-loop line strip).

ABorderStyle::Dashed
Displays a series of short square-ended dashes or line segments.
Definition ABorderStyle.h:35

ARenderContext
Render context passed to AView::render.
Definition ARenderContext.h:43

ASolidBrush
