data Renderable

A Renderable is a record of functions required to layout a graphic element.

Constructors

Renderable

Fields

minsize :: CRender RectSize

a Cairo action to calculate a minimum size,

render :: Rect -> CRender ()

a Cairo action for drawing it within a specified rectangle.

class ToRenderable a where

A type class abtracting the conversion of a value to a Renderable.

emptyRenderable :: Renderable

spacer :: RectSize -> Renderable

addMargins :: (Double, Double, Double, Double) -> Renderable -> Renderable

fillBackground :: CairoFillStyle -> Renderable -> Renderable

vertical :: [(Double, Renderable)] -> Renderable

horizontal :: [(Double, Renderable)] -> Renderable

grid :: [Double] -> [Double] -> [[(Int, Renderable)]] -> Renderable

Layout multiple Renderables into a grid. Arg 1 is the weights for the allocation of extra horizontal space to columns, Arg 2 is the weights for the allocation of extra vertical space to rows, and Arg 3 is the grid of renderables to be layed out. Each element of the grid is a tuple - the first item of the tuple is the drawing priority. Lower priorities get drawn first. Drawing order is significant when Renderables draw outside their edges.

allocate :: Double -> [Double] -> [Double] -> [Double]
