import ui
require "canvas"

-- create a simple Window
local win = ui.Window("RadialGradient.radius sample", "fixed", 500, 400)

-- create a Canvas
local canvas = ui.Canvas(win)
canvas.align = "all"

local gradient = canvas:RadialGradient { [0] = 0xE30940FF, [0.33] = 0xE7D702FF, [0.66] = 0x0FA895FF, [1] = 0x1373E8FF }
gradient.center = { canvas.width/2, canvas.height/2 }
gradient.radius = { canvas.width/2, canvas.height/2 }

function canvas:onPaint()
  self:fillrect(0, 0, canvas.width, canvas.height, gradient)
end

function canvas:onHover(x,y buttons)
  gradient.radius = { x, y }
end

await win:showasync()
