Thank you very much!
I am thinking actually to change my class in order to profit better of the root classes. In particular I would like to use the loop over the children nodes, do you think that I can do it easily? in the example the PersonList, that correspond to my Telescope is a TList of Persons, while my Telescope is a Vector of Modules… Do you think I better change it in TList, or I can do it equally with the vector class?
