Hi all, I'm working with the new (and excellent!!) tree widget, found out the cell_renderer_text can do editing as well, but if I change an entry, the change dissapears directly after I hit enter?!? Should the change be 'committed' by the callback? If so, the problem is: the callback prototype is not yet finished in the API reference so how do I do this?
Yes, here's what I use:
[...]
/* column for description */
cr = gtk_cell_renderer_text_new ();
g_signal_connect (G_OBJECT(cr), "edited",
G_CALLBACK(edit_description_cb),
tree_model);
[...]
and the callback:
[...]
void
edit_description_cb (GtkCellRendererText *cell,
const gchar *path_string,
const gchar *new_text,
gpointer data)
{
GtkTreeModel *tree_model = (GtkTreeModel*) data;
GtkTreePath *path = gtk_tree_path_new_from_string (path_string);
GtkTreeIter ti;
gchar *old_text;
gtk_tree_model_get_iter (tree_model, &ti, path);
gtk_tree_model_get (tree_model, &ti, DESCRIPTION_COLUMN, &old_text, -1);
g_free (old_text);
gtk_tree_store_set (GTK_TREE_STORE(tree_model), &ti, DESCRIPTION_COLUMN,
new_text, -1);
gtk_tree_path_free (path);
}
[...]
There is a nice example on gtk-demo, also.
(b.t.w. if somebody is interested in code to get a tree-like directory and file structure, I have something almost ready).
I am, I have done something also (a directory tree that loads subdirs when you double-click) and would like to see what you've done. []s! -- kov debian org: Gustavo Noronha <http://people.debian.org/~kov> Debian: <http://www.debian.org> * <http://debian-br.cipsga.org.br>
