Hiding individual TreeRows

[Matt Bragano <maestro485 comcast net>]

Hi all,

I've been experimenting with different ways to hide individual TreeRows 
on the fly, but with limited success.  Basically if a row's name begins 
with a " . " then I'd like to hide it, but not necessarily erase it from 
the TreeView using erase() since I'd like to be able to reverse this 
action without recreating the entire view.  I was looking around the 
mailing list archives and I stumbled upon this post:

http://marc.theaimsgroup.com/?l=gtkmm&m=109957757907166&w=2

That appears to be in the ballpark of what I'd like to do, but I'm not 
sure exactly how to implement it (I'm new to both c++ and gtkmm).

The relevant code I've been kicking around is this:

void hide_hidden_files() {

   Gtk::TreeModel::Children children = refTreeModel->children();

   Gtk::TreeModel::Children::iterator iter = children.begin();

   while(iter != children.end()){


      Gtk::TreeModel::Row row = *iter;

      Glib::ustring colName = row[mColumns.colName];

      if(colName[0] == 46){  //46 being ascii " . "

         //something here to hide the row (??)
         //This next line works, but I'd rather hide the row
         //rather than erase() it.

         iter = refTreeModel->erase(iter);

      } else { iter++; }

  }

}

This looks a little sloppy, but I'm learning as I go.  Any tips are much 
appreciated.

Thanks,
