Looks like the attachment is missing. > The GtkTreeView doesn't seem to reflect the changes made to the > GtkListStore. No idea if it could be this, but someone recently had a similar issue because he's TreeView wasn't inside a ScrolledWindow, and GTK3 TreeView has a resizing bug in this case (so the value where there but the view was too small to show them). So, is your TreeView in a ScrolledWindow, or does it help? > I iterated through the GtkListStore itself and found that > values were being added. > > if (gtk_tree_model_get_iter_first(GTK_TREE_MODEL(list_store), &iter)){ > gtk_tree_model_get(GTK_TREE_MODEL(list_store), &iter, 0, > &test_value, -1); > g_debug(" - Value: \"%s\"", test_value); > }else{ > g_warning("GtkTreeModel contains no elements!"); > } > while (gtk_tree_model_iter_next(GTK_TREE_MODEL(list_store), &iter)){ > memset(test_value, 0, sizeof(gchararray)); > gtk_tree_model_get(GTK_TREE_MODEL(list_store), &iter, 0, > test_value, -1); > g_debug(" - Value: \"%s\"", test_value); Wow, I don't know what you are trying to do here with the memset() and stuff. "gchararray" in this context actually means "a C string", `gchar*`. Also, gtk_tree_model_get() *duplicates* the data, so you want to free the memory afterwards. gchar *str; gtk_tree_model_get(model, &iter, 0, &str, -1); // ... g_free(str); Not to duplicate code you also probably would rather implement iteration like this: if (gtk_tree_model_get_iter_first(...)) { do { ... } while (gtk_tree_model_iter_next(...)); } > I'm wondering if the mutilated strings is what's causing my problem.

This may be a reason if the data is actually wrong (I mean, if it's not your fetching when printing that is), because GtkCellRendererText requires UTF-8-encoded text. But if this was the error, you'd see a lot of warnings in the terminal. I see 3 possibilities: 1) the tree model is not properly connected to the tree view; 2) you didn't add CellRenderers; 3) your tree view isn't packed in a ScrolledWindow and you experience the above-mentioned bug. Hope it helps. Regards, Colomban _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
