The event returns no value.

--! luart-extensions
import ui
require "canvas"

-- creates a simple window
local win = ui.Window("Canvas:onCreate() event sample", 640, 400)
local Canvas = ui.Canvas(win, 320, 200)

-- Canvas:onCreate() event to center and draw text on the Canvas widget
function Canvas:onCreate()
  self:begin()
  self:center()
  self:clear(0x000000FF)
  self:print("Hello LuaRT !", 130, 100, 0xFFA300FF)
  self:flip()
end

await win:showasync()
