hi
sound stupid
but found all necessary files for understanding of structures in the folder stuff/structures.
i said that cause regular help for append , get , set , scalar.... are useless : in all that examples objects are already created and it's difficult to see the relationships. Waste weeks triyng to find theses relationships...
after reading stuff you can easily define structures , soething really badly documented but really amzing (powerfuuuullllllll) and in fact ... really simple

i have look not too much look at this, i am not sure of the purpose of this function, is it only for graphical stuff

no
at this time ive understood how to manage it inside a window. ie graphically.
but there is a way to manage structures inside list ....
it remember me class definition in c++

some explanation could be found here.
sorry for such a bad translation in english....
(i do my best ... it should be better & better as time goes...)
