[pygtk] making a editable treeview stay in edit mode

I use this code as callback of 'key-press-event' on Tab to achieve what you
are looking for. 

The key ise 'treeview.set_cursor', that lets you say if you want to want to
get into editing mode::

   def set_cursor(path, focus_column=None, start_editing=False)

the example is more complicated than you need, as I onnly use editing mode
if the column represents an editable data and I call self.get_direct_edit for that.

    def key_tree_Tab(self, treeview, event, data):
        path, col = treeview.get_cursor()
        ## only visible columns!!
        columns = [c for c in treeview.get_columns() if c.get_visible()]
        colnum = columns.index(col)
        if colnum + 1 < len(columns):
            next_column = columns[colnum + 1]
            next_field_name = next_column.get_data('field_name')
            gobject.idle_add(treeview.set_cursor, path,
                             next_column, self.get_direct_edit(next_field_name) )
        else:
            tmodel = treeview.get_model()
            titer = tmodel.iter_next(tmodel.get_iter(path))
            if titer is None:
                titer = tmodel.get_iter_first()
            path = tmodel.get_path(titer)
            
            next_column = columns[0]
            next_field_name = next_column.get_data('field_name')
            gobject.idle_add(self.treeview.set_cursor, path, next_column,
                             self.get_direct_edit(next_field_name) )
        return False
