Tree.readonly | LuaRT free and open source Windows programming framework for Lua

Tree.readonly read/write property

Controls whether the Tree is editable by the user, a true value meaning that the Tree is readonly (the default).

Example


local ui = require "ui"

local win = ui.Window("List.border sample", 320, 270)
local tree = ui.Tree(win, {"Item1", "Item2", "Item3"})
tree:center()

local button = ui.Button(win, "Enable Tree item edition", 80, 10)

function update_status()
    win:status(tree.readonly and "Tree is not editable by user" or "Tree is editable by user")
end

function button:onClick()
  tree.readonly = not tree.readonly
  button.text = tree.readonly and "Enable Tree item edition" or "Disable Tree item edition"
  update_status()
end

update_status()

ui.run(win):wait()
