Hi everybody.
I obtain the following errors when launching my application that contains a
notebook, and in one of its page there are three combobox with the associated
treeviews:
(when opening the tab)
barcode_buttons[2561]: GLIB CRITICAL ** Gtk - gtk_tree_store_get_path: assertion
`iter->user_data != NULL' failed
barcode_buttons[2561]: GLIB CRITICAL ** Gtk - gtk_tree_store_get_path: assertion

barcode_buttons[2561]: GLIB CRITICAL ** Gtk - gtk_tree_store_get_path: assertion
`iter->user_data != NULL' failed
(when closing the tab)
barcode_buttons[2561]: GLIB CRITICAL ** GLib-GObject - g_object_unref: assertion

barcode_buttons[2561]: GLIB CRITICAL ** GLib-GObject - g_object_get_data:

barcode_buttons[2561]: GLIB WARNING ** Gtk - gtktreemodel.c:1949: bad row

barcode_buttons[2561]: GLIB CRITICAL ** GLib-GObject - g_object_get_data:
assertion `G_IS_OBJECT (object)' failed
barcode_buttons[2561]: GLIB WARNING ** Gtk - gtktreemodel.c:1949: bad row
reference, proxy has no outstanding row references
What they means?
I use the following code to create a model for the tree:
GtkTreeModel *
190 create_model ( void ) {
191
192 GtkTreeIter iter;
193 GtkTreeStore *store = NULL;
194 GtkTreeSelection *select = NULL;
195 GtkWidget *treeview = NULL;
196 ll *tmp = top->ref->first;
197
198 store = gtk_tree_store_new(NUM_COL, G_TYPE_STRING);
199
200 gtk_tree_store_append(store, &iter, NULL);
201 gtk_tree_store_set(store, &iter,
202 STRING_COL, "<Nothing>",
203 -1);
204
205 while (tmp != NULL) {
206 gtk_tree_store_append(store, &iter, NULL);
207 gtk_tree_store_set(store, &iter,
208 STRING_COL, tmp->contenuto,
209 -1);
210 tmp = tmp->next;
211 }
212
213 treeview = gtk_tree_view_new_with_model(GTK_TREE_MODEL(store));
214 select = gtk_tree_view_get_selection(GTK_TREE_VIEW(treeview));
215 gtk_tree_selection_set_mode(select, GTK_SELECTION_SINGLE);
216
217 return GTK_TREE_MODEL(store);
218 }
and this one to create a text renderer:
void add_renderer ( GtkComboBox *combo ) {
273
274 GtkCellRenderer *render = NULL;
275 GtkTreePath *path = NULL;
276 GtkTreeModel *mod = NULL;
277 GtkTreeIter iter;
278
279 render = gtk_cell_renderer_text_new();
280 gtk_cell_layout_pack_start(GTK_CELL_LAYOUT(combo), render, TRUE);
281 gtk_cell_layout_set_attributes(GTK_CELL_LAYOUT(combo), render,
282 "text", STRING_COL,
283 NULL);
284
285 path = gtk_tree_path_new_from_indices(0, 1, -1);
286 mod = gtk_combo_box_get_model(combo);
287 gtk_tree_model_get_iter(mod, &iter, path);
288 gtk_tree_path_free(path);
289 gtk_combo_box_set_active_iter(combo, &iter);
290
291 }
then I use this code to get data from the combobox:
369 result = gtk_combo_box_get_active_iter(GTK_COMBO_BOX(c.dataCombo),
&iter);
370 model = gtk_combo_box_get_model(GTK_COMBO_BOX(c.dataCombo));
371 gtk_tree_model_get(model, &iter,
372 STRING_COL, &tf.data,
373 -1);
374 printf("Getted data: %s\n", tf.data);
375 g_object_unref(model);
Thanks in advance,
Omar
