## Detailed Description

An action of which only one in a group can be active.

A Gtk::RadioAction is similar to Gtk::RadioMenuItem. A number of radio actions can be linked together so that only one may be active at any one time.

Returns
  The value of the currently active group member.

Group Gtk::RadioAction::get_group | ( |  | ) |

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:

[C example ellipted]

Since gtkmm 2.4:

Returns
  The list representing the radio group for this object.

static GType Gtk::RadioAction::get_type | ( |  | ) |

static

Get the GType for this class, for use with the underlying GObject type system.

GtkRadioAction* Gtk::RadioAction::gobj | ( |  | ) |

inline

Provides access to the underlying C GObject.

const GtkRadioAction* Gtk::RadioAction::gobj | ( |  | ) | const

inline

Provides access to the underlying C GObject.

GtkRadioAction* Gtk::RadioAction::gobj_copy | ( |  | ) |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

void Gtk::RadioAction::join_group | ( | const Glib::RefPtr< RadioAction >& | group_source | ) |

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

Use this in language bindings instead of the get_group() and set_group() methods

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

[C example ellipted]

Since gtkmm 3.0:

Parameters

  group_source | A radio action object whos group we are joining, or `0` to remove the radio action from its group.

virtual void Gtk::RadioAction::on_changed | ( | const Glib::RefPtr< RadioAction >& | current | ) |

protected virtual

This is a default handler for the signal signal_changed().

Glib::PropertyProxy< int > Gtk::RadioAction::property_current_value | ( |  | ) |

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

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns
  A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< int > Gtk::RadioAction::property_current_value | ( |  | ) | const

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

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy< int > Gtk::RadioAction::property_value | ( |  | ) |

The value returned by gtk_radio_action_get_current_value() when this action is the current action of its group.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns
  A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< int > Gtk::RadioAction::property_value | ( |  | ) | const

The value returned by gtk_radio_action_get_current_value() when this action is the current action of its group.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

void Gtk::RadioAction::set_current_value | ( | int | current_value | ) |

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

Since gtkmm 2.10:

Parameters

  current_value | The new value.

void Gtk::RadioAction::set_group | ( | Group& | group | ) |

Glib::SignalProxy1< void,const Glib::RefPtr<RadioAction>& > Gtk::RadioAction::signal_changed | ( |  | ) |

Slot Prototype:
  `void on_my_changed(const Glib::RefPtr<RadioAction>& current)`

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

Since gtkmm 2.4:

Parameters

  current | The member of actions group which has just been activated.
