Description Mattias Karlsson 2005-03-31 14:58:17 UTC

When trying to copy a treeview I get the following error:

/home/enki/src/gazpacho/gazpacho/widget.py:599: GtkWarning: file gtktreeview.c:
line 9317 (gtk_tree_view_set_headers_clickable): assertion
`tree_view->priv->model != NULL' failed
  self.gtk_widget.set_property(prop.klass.id, prop.value)


When pasting it the column headers doesn't show anymore.

Comment 1 Mattias Karlsson 2005-04-02 10:17:26 UTC

After the changed made to the Clipboard and how Copy/Paste works there are now a
new problem instead. I get the following exception when pasting the tree view.

Traceback (most recent call last):

Comment 2 Lorenzo Gil Sanchez 2005-04-07 00:44:20 UTC

Fixed in trunk.

I removed the columns of the treeview since there is not support to edit or save
them and because of that we lost then after a copy-paste operation

Comment 3 Mattias Karlsson 2005-04-07 10:20:36 UTC

The only problem with this is that it isn't as obvious that this is a tree view
anymore, but I guess we can live with that. It would be nice to implement some
simple support for adding columns later though (if that is possible).

Comment 4 Lorenzo Gil Sanchez 2005-04-07 12:37:52 UTC

Sure, that's one of the initial goals of Gazpacho: support for TreeView design.
We just need a little bit more of infraestructure
