LinearGradient.stop read/write property
Get or set the ending two-dimensional coordinates of the linear gradient
To set this property, use a table as a list of two numbers, for example { 0, 0 }
When getting this property, you can access the coordinates by using the fields x and y
Example
local ui = require "ui"
require "canvas"
-- create a simple Window
local win = ui.Window("LinearGradient.stop sample", "fixed", 500, 400)
-- create a Canvas
local canvas = ui.Canvas(win)
canvas.align = "all"
local gradient = canvas:LinearGradient { [0] = 0xE30940FF, [0.33] = 0xE7D702FF, [0.66] = 0x0FA895FF, [1] = 0x1373E8FF }
gradient.start = { 0, 0 }
gradient.stop = { canvas.width, 0 }
function canvas:onPaint()
self:fillrect(0, 0, canvas.width, canvas.height, gradient)
end
win:show()
-- update user interface
repeat
ui.update()
until not win.visible
