gtk_radio_action_new ()

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

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().

Since: 2.4

gtk_radio_action_get_group ()

GSList *
gtk_radio_action_get_group (GtkRadioAction *action);

Returns the list representing the radio group for this object. Note that the returned list is only valid until the next change to the group.

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

1
2
3
4
5
6
7
8
9
10

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);
  }

Since: 2.4

gtk_radio_action_set_group ()

void
gtk_radio_action_set_group (GtkRadioAction *action,
                            GSList *group);

Sets the radio group for the radio action object.

Since: 2.4

gtk_radio_action_get_current_value ()

gint
gtk_radio_action_get_current_value (GtkRadioAction *action);

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

Since: 2.4

gtk_radio_action_set_current_value ()

void
gtk_radio_action_set_current_value (GtkRadioAction *action,
                                    gint current_value);

Sets the currently active group member to the member with value property current_value .

Since: 2.10

struct GtkRadioAction

struct GtkRadioAction;

The GtkRadioAction struct contains only private members and should not be accessed directly.

The “current-value” property

  “current-value”            gint

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

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.

Flags: Read / Write

Default value: 0

Since: 2.4

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.

Flags: No Recursion
