GtkRadioMenuItem has a main CSS node with name menuitem, and a subnode with name radio, which gets the .left or .right style class.

gtk_radio_menu_item_new ()

GtkWidget *
gtk_radio_menu_item_new (GSList *group);

Creates a new GtkRadioMenuItem.

gtk_radio_menu_item_new_with_label ()

GtkWidget *
gtk_radio_menu_item_new_with_label (GSList *group,
                                    const gchar *label);

Creates a new GtkRadioMenuItem whose child is a simple GtkLabel.

gtk_radio_menu_item_new_with_mnemonic ()

GtkWidget *
gtk_radio_menu_item_new_with_mnemonic (GSList *group,
                                       const gchar *label);

Creates a new GtkRadioMenuItem containing a label. The label will be created using gtk_label_new_with_mnemonic(), so underscores in label indicate the mnemonic for the menu item.

gtk_radio_menu_item_new_from_widget ()

GtkWidget *
gtk_radio_menu_item_new_from_widget (GtkRadioMenuItem *group);

Creates a new GtkRadioMenuItem adding it to the same group as group .

gtk_radio_menu_item_new_with_label_from_widget ()

GtkWidget *
gtk_radio_menu_item_new_with_label_from_widget
                               (GtkRadioMenuItem *group,
                                const gchar *label);

Creates a new GtkRadioMenuItem whose child is a simple GtkLabel. The new GtkRadioMenuItem is added to the same group as group .

gtk_radio_menu_item_new_with_mnemonic_from_widget ()

GtkWidget *
gtk_radio_menu_item_new_with_mnemonic_from_widget
                               (GtkRadioMenuItem *group,
                                const gchar *label);

Creates a new GtkRadioMenuItem containing a label. The label will be created using gtk_label_new_with_mnemonic(), so underscores in label indicate the mnemonic for the menu item.

The new GtkRadioMenuItem is added to the same group as group .

gtk_radio_menu_item_set_group ()

void
gtk_radio_menu_item_set_group (GtkRadioMenuItem *radio_menu_item,
                               GSList *group);

Sets the group of a radio menu item, or changes it.

gtk_radio_menu_item_get_group ()

GSList *
gtk_radio_menu_item_get_group (GtkRadioMenuItem *radio_menu_item);

Returns the group to which the radio menu item belongs, as a GList of GtkRadioMenuItem. The list belongs to GTK+ and should not be freed.

gtk_radio_menu_item_join_group ()

void
gtk_radio_menu_item_join_group (GtkRadioMenuItem *radio_menu_item,
                                GtkRadioMenuItem *group_source);

Joins a GtkRadioMenuItem object to the group of another GtkRadioMenuItem object.

This function should be used by language bindings to avoid the memory manangement of the opaque GSList of gtk_radio_menu_item_get_group() and gtk_radio_menu_item_set_group().

A common way to set up a group of GtkRadioMenuItem instances is:

    gtk_radio_menu_item_join_group (radio_item, last_item);
    last_item = radio_item;
  }
