## Implemented Interfaces

GtkRadioMenuItem implements GtkActivatable, AtkImplementorIface and GtkBuildable.

## Properties

      "group"                    GtkRadioMenuItem*     : Write

## Signals

      "group-changed"                                  : Run First

## 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);
    }

## Details

### GtkRadioMenuItem

    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 ()

    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.

`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

Since 2.4

### 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`.

`group` : | an existing GtkRadioMenuItem
`label` : | the text for the label
Returns : | The new GtkRadioMenuItem

Since 2.4

### 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.

### gtk_radio_menu_item_group

    #define gtk_radio_menu_item_group gtk_radio_menu_item_get_group

### Warning

`gtk_radio_menu_item_group` is deprecated and should not be used in newly-written code.

Deprecated compatibility macro. Use `gtk_radio_menu_item_get_group()` instead.

### 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.

`radio_menu_item` : | a GtkRadioMenuItem.
`group` : | the new group.

### 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.

`radio_menu_item` : | a GtkRadioMenuItem.
Returns : | the group of `radio_menu_item`.

## Property Details

### The `"group"` property

      "group"                    GtkRadioMenuItem*     : Write

The radio menu item whose group this widget belongs to.

Since 2.8

## Signal Details

### The `"group-changed"` signal

    void                user_function                      (GtkRadioMenuItem *radiomenuitem,
                                                            gpointer          user_data)          : Run First

`radiomenuitem` : | the object which received the signal.
`user_data` : | user data set when the signal handler was connected.
