RadioMenuItemRef

public struct RadioMenuItemRef : RadioMenuItemProtocol, GWeakCapturing

A radio menu item is a check menu item that belongs to a group. At each instant exactly one of the radio menu items from a group is selected.

The group list does not need to be freed, as each GtkRadioMenuItem will remove itself and its list item when it is destroyed.

The correct way to create a group of radio menu items is approximatively this:

How to create a group of radio menu items.

(C Language Example):

GSList *group = NULL;
GtkWidget *item;
gint i;

for (i = 0; i < 5; i++)
{
  item = gtk_radio_menu_item_new_with_label (group, "This is an example");
  group = gtk_radio_menu_item_get_group (GTK_RADIO_MENU_ITEM (item));
  if (i == 1)
    gtk_check_menu_item_set_active (GTK_CHECK_MENU_ITEM (item), TRUE);
}

CSS nodes

(plain Language Example):

menuitem
├── radio.left
╰── <child>

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

The RadioMenuItemRef type acts as a lightweight Swift reference to an underlying GtkRadioMenuItem instance. It exposes methods that can operate on this data type through RadioMenuItemProtocol conformance. Use RadioMenuItemRef only as an unowned reference to an existing GtkRadioMenuItem instance.

  • ptr 
    Untyped pointer to the underlying `GtkRadioMenuItem` instance.

    For type-safe access, use the generated, typed pointer radio_menu_item_ptr property instead.
