tree widget in python

[Gilles Bourgeois]

hi ,from france
does anyone gnows if tree widget exists in wxpython
I need a kind of expandable graphical tree  (like when brosing a file
system with the Windoze file explorer)

My aim is to use a tree to have a expandable view of a C structure ;

this could be :
typedef {
 char* toto;
 struct titi {
 int x;
 int y;}
}S

and I want to  give a graphical representation of S, the user then may
access to all fields of the S 'C structure' and fill in the parameter.

TIA
