Example
local ui = require "ui"
-- create a simple window
local win = ui.Window("Tree.x sample", 600, 300)
local button = ui.Button(win, "Change Tree position", 240)
local tree = ui.Tree(win, {'Item 1', 'Item 2'}, 10, 140)
function button:onClick()
tree.x = math.random(10, win.width-tree.width)
tree.y = math.random(40, win.height-tree.height)
end
-- shows the window
win:show()
-- update user interface and increase Tree horizontal position
repeat
ui.update()
until not win.visible
