Clueless

[Lars Clausen]

Now I have now managed to get the menu up, and in a fairly nice way (as you
suggested, with a new ObjectOp).  Now I just have the problem that after
the menu has been popped up, whether I have selected anything or not, all
input and refresh of that window stops.  I am really without a clue as to
why this happens.  I suppose there should be some cleanup or something, but
found nothing like it in the code or in the GTK docs.  You got any ideas?

This is the function that pops up the menu:

/* This contains the point that was clicked to get this menu */
Point *object_menu_clicked_point;

void
popup_object_menu(GdkEventButton *bevent, DDisplay *ddisp)
{
  Diagram *diagram;
  real click_distance;
  Object *obj;
  Point *clickedpoint;
  GtkMenu *menu = NULL;
  GList *selected_list;

printf("Trying a middle menu\n");

  diagram = ddisp->diagram;
  if (diagram->data->selected_count != 1) return;
  selected_list = diagram_get_sorted_selected(diagram);
  /* Have to have exactly one selected object */
  if (selected_list == NULL || g_list_next(selected_list) != NULL) {
    message_error("Selected list is %s while selected_count is %d\n",
                  (selected_list?"long":"empty"), diagram->data->selected_count);
    return;
  }
  obj = (Object *)g_list_first(selected_list)->data;
  if (obj->ops->get_object_menu == NULL)
    return;
printf("Trying a middle menu for %s object\n", obj->type->name);
  /* Find the nearest object */
  ddisplay_untransform_coords(ddisp,
                              (int)bevent->x, (int)bevent->y,
                              &clickedpoint->x, &clickedpoint->y);
  /* Possibly react differently at a handle? */
  /* Get its menu, if it has registered any */
  menu = (obj->ops->get_object_menu)(obj, clickedpoint);
  if (menu == NULL) return;
printf("Found a middle menu for %s object\n", obj->type->name);
  object_menu_clicked_point = clickedpoint;
  /* Pop up the menu */
  popup_shell = ddisp->shell;
  /* FIXME:  Is menu->menu the right thing? */
  gtk_menu_popup(menu, NULL, NULL, NULL, NULL, 0, 0);
}

this is the menu-creating function:

static GtkMenu *
polyline_get_object_menu(Object *obj, Point *clickedpoint)
{
  GtkMenu *menu;
  GtkAccelGroup *accel_group;
  Polyline *polyline = (Polyline *)obj;

  if (polyline_item_factory == NULL) {
    accel_group = gtk_accel_group_new ();
    polyline_item_factory = gtk_item_factory_new (GTK_TYPE_MENU, "<PolyLine>", 
                                          accel_group);
    gtk_item_factory_create_items (polyline_item_factory,
                                   sizeof(polyline_menu_items)/
                                   sizeof(GtkItemFactoryEntry),
                                   polyline_menu_items, NULL);
  }
  menu = GTK_MENU(gtk_item_factory_get_widget(polyline_item_factory, "<PolyLine>"));
  /* Set entries sensitive/selected etc here */
  gtk_widget_set_sensitive(gtk_item_factory_get_widget(polyline_item_factory, 
"<PolyLine>/Add Corner"), 1);
  gtk_widget_set_sensitive(gtk_item_factory_get_widget(polyline_item_factory, 
"<PolyLine>/Delete Corner"), polyline->poly.numpoints > 2);
  return menu;
}
