They only need to be appended once, to set up the treeview -- once that's done you should be fine.

[pygtk] GtkWarning: gtk_tree_view_append_column
Hi All, I have been using a treeview to display data. The first time I load it data everything works, but sometimes when I try to load another or the same data file, this message is sent: " GtkWarning: gtk_tree_view_append_column: assertion `column->tree_view == NULL' failed self._spp_treeview.append_column(self.spp)" At the second time this message is sent, the data is improperly loaded. The method I use to clear treeview is: self.liststore.clear() self.spp.clear() ## gtk.TreeViewColumn self.seqs.clear()##gtk.TreeViewColumn To create a new set of data on Liststore: for rows in self.data: ## where self.data contains tuples of data self.liststore.append([rows[0], rows[1]]) To display new set of data: self._seqs_treeview.append_column(self.seqs) self._spp_treeview.append_column(self.spp) I can't understand where is the problem and I didn't find any solved similiar problem on google. Does anyone could help me?
