# Gtk::RadioAction Class Reference

Inheritance diagram for Gtk::RadioAction:

[legend]
List of all members.

## 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.

## Public Types

typedef RadioButtonGroup | Group

## Public Member Functions

int | get_current_value () const
| Obtains the value property of the currently active member of the group to which action belongs.
Group | get_group ()
| Returns: the list representing the radio group for this object.
const GtkRadioAction* | gobj () const
| Provides access to the underlying C GObject.
GtkRadioAction* | gobj ()
| Provides access to the underlying C GObject.
GtkRadioAction* | gobj_copy ()
| Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

| The value property of the currently active member of the group to which this action belongs.
Glib::PropertyProxy<int> | property_current_value ()
| The value property of the currently active member of the group to which this action belongs.
Glib::PropertyProxy_ReadOnly< int > | property_value () const
| The value returned by gtk_radio_action_get_current_value() when this action is the current action of its group.
Glib::PropertyProxy<int> | property_value ()
| The value returned by gtk_radio_action_get_current_value() when this action is the current action of its group.
void | set_current_value (int current_value)
| Sets the currently active group member to the member with value property current_value .
void | set_group (Group& group)
Glib::SignalProxy1< void, const Glib::RefPtr<RadioAction >&> | signal_changed ()
| The changed signal is emitted on every member of a radio group when the active member is changed.
virtual | ~RadioAction ()

Returns:
  The value of the currently active group member

Since gtkmm 2.4:

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

Returns: the list representing the radio group for this object.

Returns:
  The list representing the radio group for this object

Since gtkmm 2.4:

const GtkRadioAction* Gtk::RadioAction::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C GObject.

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

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 property of the value, 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 that allows you to get or set the property of the value, 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.

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 | ( |  | ) |

The changed signal is emitted on every member of a radio group when the active member is changed.

The signal is emitted after the activate signals for the previous and current active members.

Parameters:

  | current | the member of this action's group which has just been activated.

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