Description

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:

Example 31. How to create a group of radio menu items.

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);
}

typedef struct _GtkRadioMenuItem GtkRadioMenuItem;

The structure contains only private data that must be accessed through the interface functions.


gtk_radio_menu_item_new ()

GtkWidget*          gtk_radio_menu_item_new             (GSList *group);

Creates a new GtkRadioMenuItem.

group :

the group to which the radio menu item is to be attached

Returns :

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.

group :

the group to which the radio menu item is to be attached

label :

the text for the label

Returns :

a new GtkRadioMenuItem

gtk_radio_menu_item_new_with_mnemonic ()

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.

group :

group the radio menu item is inside

label :

the text of the button, with an underscore in front of the mnemonic character

Returns :

a new GtkRadioMenuItem

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.

group :

An existing GtkRadioMenuItem

Returns :

The new GtkRadioMenuItem
