## Functions

### gtk_radio_action_new ()

    GtkRadioAction *
    gtk_radio_action_new (const gchar *name,
                          const gchar *label,
                          const gchar *tooltip,
                          const gchar *stock_id,
                          gint value);

`gtk_radio_action_new` has been deprecated since version 3.10 and should not be used in newly-written code.

Creates a new GtkRadioAction object. To add the action to a GtkActionGroup and set the accelerator for the action, call `gtk_action_group_add_action_with_accel()`.

#### Parameters

name | A unique name for the action |
label | The label displayed in menu items and on buttons, or `NULL`. | [allow-none]
tooltip | A tooltip for this action, or `NULL`. | [allow-none]
stock_id | The stock icon to display in widgets representing this action, or `NULL`. | [allow-none]
value | The value which `gtk_radio_action_get_current_value()` should return if this action is selected. |

#### Returns

a new GtkRadioAction

### gtk_radio_action_get_group ()

    GSList *
    gtk_radio_action_get_group (GtkRadioAction *action);

    GSList *group = NULL;
    GtkRadioAction *action;

    while ( ...more actions to add... /)
      {
         action = gtk_radio_action_new (...);

         gtk_radio_action_set_group (action, group);
         group = gtk_radio_action_get_group (action);
      }

#### Parameters

action | the action object |

#### Returns

the list representing the radio group for this object.

### gtk_radio_action_set_group ()

    void
    gtk_radio_action_set_group (GtkRadioAction *action,

### gtk_radio_action_join_group ()

    void
    gtk_radio_action_join_group (GtkRadioAction *action,
                                 GtkRadioAction *group_source);

`gtk_radio_action_join_group` has been deprecated since version 3.10 and should not be used in newly-written code.

Joins a radio action object to the group of another radio action object.

Use this in language bindings instead of the `gtk_radio_action_get_group()` and `gtk_radio_action_set_group()` methods

A common way to set up a group of radio actions is the following:

    1
    2
    3
    4
    5
    6
    7
    8

      {
         action = gtk_radio_action_new (...);

         gtk_radio_action_join_group (action, last_action);
         last_action = action;

## Types and Values

### struct GtkRadioAction

    struct GtkRadioAction;

## Property Details

### The `“current-value”` property

      “current-value”            gint

The value property of the currently active member of the group to which this action belongs.

`GtkRadioAction:current-value` has been deprecated since version 3.10 and should not be used in newly-written code.

Flags: Read / Write

Default value: 0

Since: 2.10

### The `“group”` property

      “group”                    GtkRadioAction *

Sets a new group for a radio action.

Flags: Write

Since: 2.4

### The `“value”` property

      “value”                    gint

The value is an arbitrary integer which can be used as a convenient way to determine which action in the group is currently active in an ::activate or ::changed signal handler. See `gtk_radio_action_get_current_value()` and GtkRadioActionEntry for convenient ways to get and set this property.

`GtkRadioAction:value` has been deprecated since version 3.10 and should not be used in newly-written code.

Flags: Read / Write

Since: 2.4

## Signal Details

### The `“changed”` signal

    void
    user_function (GtkRadioAction *action,
                   GtkRadioAction *current,
                   gpointer        user_data)

The ::changed signal is emitted on every member of a radio group when the active member is changed. The signal gets emitted after the ::activate signals for the previous and current active members.

`GtkRadioAction::changed` has been deprecated since version 3.10 and should not be used in newly-written code.

#### Parameters

action | the action on which the signal is emitted |
current | the member of `action` 's group which has just been activated |
user_data | user data set when the signal handler was connected. |
