RE: How to get a string from treeview

[martyn 2 russell bt com]

You should be able to:
(oh and have you looked at gtk-demo? - at run dialog, enter 'gtk-demo')


GtkTreeModel *model = NULL;
GtkTreeIter iter;
GtkTreeSelection *selection = NULL;

gchar *value = NULL;

selection = gtk_tree_view_get_selection(GTK_TREE_VIEW(treeview));

/* this only works for GTK_SELECTION_SINGLE */
if(gtk_tree_selection_get_selected(selection, &model, &iter) == FALSE)
        return; /* no selection */

gtk_tree_model_get(GTK_TREE_MODEL(model), &iter, col, &value, -1);       

/* do something with value */

if(value != NULL) 
        g_free(value);

Regards,
Martyn
