Re: Lua for GUIs

[Gaspard Bucher <gaspard@...>]

Once you have a table with definitions either for create or update:

function view:update(def)

  -- set self with attributes

  -- set children

  for name, child_def in pairs(def.children) do

    if self.child[name] then

      self.child[name]:update(child_def)

    else

      local class_constr = classes[child_def.class]

      self.child[name] = class_constr(child_def)

    end

  end

end

That's the basic idea..

Indeed.

Hm, can you give a bit longer example of your idea?  I seem not to grasp
what you mean here...
