"order" parameter for LuaGuiElement#add

[PFQNiet]

Having just implemented this myself in Lua, I figured I'd ask if this could be made part of the engine-side code:

Code: Select all

local function findIndexForNewElement(parent, order)
  local index = 1
  for i=1,#parent.children do
    if (parent.children[i].tags['order'] or "") < order then
      index = index + 1
    else
      break
    end
  end
  return index
end

local order = "a"
parent.add{
  -- ...
  tags = {order = order},
  index = findIndexForNewElement(parent, order)
}

It would be nice if instead I could just provide an "order" parameter to GUI elements I create, such that when a new GUI element is created with an order, it slots itself in the correct place, rather than me having to iterate through the elements on the Lua side.
