[pygtk] completion and TreeStore child element

[Alessandro Dentella]

Hi,

  I wanted to add grouping in a completion. I used a  TreeStore in the
  completion, added correctly father/child element... but the completion
  shows it collapsed.

  I see that completion does not have .expand_all() that is a method of
  TreeView... is it any possibile?

  And in case it is possible, is it any possible for the used to collapse
  single entries?

  TIA
