void Gtk::RadioMenuItem::constructor | ( | const Group& | group | ) | `[protected]`

Group Gtk::RadioMenuItem::get_group | ( |  | ) |

Returns the group to which the radio menu item belongs, as a List of Gtk::RadioMenuItem.

The list belongs to GTK+ and should not be freed.

Returns:
  The group of radio_menu_item.

const GtkRadioMenuItem* Gtk::RadioMenuItem::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C GtkObject.

Reimplemented from Gtk::CheckMenuItem.

GtkRadioMenuItem* Gtk::RadioMenuItem::gobj | ( |  | ) | `[inline]`

virtual void Gtk::RadioMenuItem::on_group_changed | ( |  | ) | `[protected, virtual]`

void Gtk::RadioMenuItem::reset_group | ( |  | ) |

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

Glib::SignalProxy0< void > Gtk::RadioMenuItem::signal_group_changed | ( |  | ) |

Emitted when the group of radio menu items that a radio menu item belongs to changes.

This is emitted when a radio menu item switches from being alone to being part of a group of 2 or more menu items, or vice-versa, and when a buttton is moved from one group of 2 or more menu items to a different one, but not when the composition of the group that a menu item belongs to changes.

Prototype:
  `void on_my_group_changed()`
