Tree.items read/write property iterable
Provides access to the list of Tree items.
Reading this property returns a table that contains a list of TreeItem.
This table can be indexed by item text or by an integer index. Using a wrong index or an invalid text will return a nil value.
An integer index represents the item position in the Tree, starting from 1 (See TreeItem.index property).
Setting this property will change all the items in the List. It expects a table that contains a list of strings (each string will be an item in the Tree)
Example
local ui = require "ui"
local win = ui.Window("Tree.items sample", "fixed", 320, 240)
local button = ui.Button(win, "Iterate over Tree.items", 104, 10)
local tree = ui.Tree(win, {}, 110, 40)
tree.style ="icons"
tree.items = {
"Item 1",
"Item 2",
["Item 3"] = {
"Subitem1",
"Subitem2"
}
}
function button:onClick()
for item in each(tree.items) do
item:loadicon(sys.env.windir.."\\system32\\user32.dll", 6)
end
end
-- show the Window
win:show()
while win.visible do
ui.update()
end
