How to save the contents of a wxTreeCtrl

Krjukov_Victor · November 26, 2002, 4:54pm

Well, it seems that Amos want to save this tree to file in human
readable format - in that case cPickle is not a solution, as well as
storing the whole list as is.

It also seems to me that the following format is simple and human
readable:

Root
  Child
  Child 2
  Child that has sub-childs
    Subchild1
    Subchild2
  Child 3
  Child 4
    Subchild
      Sub-sub-child

(you show the nesting level with appropriate amount of spaces).

I also would suggest not to store Tree as a nested lists, but to write a
class. I've attached the example that I've just written which can write
itself to file and read itself from file. Enjoy ;).

How about using Python's pickle module? My understanding is
that's what
it was designed for...

Another option if you want human readable text representation of a nested
list would be to use yaml (yaml.org). It uses indentation to indicate
subobjects and looks a fair amount like what's below. (It also handles
dicts, ints, floats, strings and probably some other things).
