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.TreeViewColumnTo 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?
Thanks Fred
