Sort items in wxListCtrl

[Ric at rdo]

I am trying to create a small application in wxPython and would like
to ask for some help.

I am trying to display folders and  files in ListCtrl but sorted first
folders followed by files (like in a file manager style) but not sure
how to do this? Would I need to do this in code somehow or ListCtrl
would help me?

I am trying to do this and learn at the same time.

Would appreciate any advice. Thank you.
