DESCRIPTION
A single radio button performs the same basic function as a
Gtk2::CheckButton, as its position in the object hierarchy reflects.
It is only when multiple radio buttons are grouped together that they
become a different user interface component in their own right.
Every radio button is a member of some group of radio buttons. When
one is selected, all other radio buttons in the same group are
deselected. A Gtk2::RadioButton is one way of giving the user a choice
from many options; Gtk2::OptionMenu and Gtk2::ComboBox (added in gtk+
2.4) are alternatives.
Each constructor can take either a group or widget from that group
where the group is wanted; this is an enhancement over the C API.
Nevertheless, the _from_widget forms are provided for completeness.

METHODS
widget = Gtk2::RadioButton->new ($member_or_listref=undef,
$label=undef)
· $member_or_listref (scalar) reference to radiobutton group or a
Gtk2::RadioButton belonging to that group.
· $label (string)
Create a radio button. If $label is provided, it will be
interpreted as a mnemonic. If $member_or_listref is undef, the
radio button will be created in a new group.
widget = Gtk2::RadioButton->new_from_widget ($group, $label=undef)
· $group (Gtk2::RadioButton or undef)
· $label (string)
widget = Gtk2::RadioButton->new_with_label ($member_or_listref=undef,
$label=undef)
· $member_or_listref (scalar) reference to radiobutton group or a
Gtk2::RadioButton belonging to that group.
· $label (string)
Create a radio button with a plain text label, which will not be
interpreted as a mnemonic.
widget = Gtk2::RadioButton->new_with_label_from_widget ($group,
$label=undef)
· $group (Gtk2::RadioButton or undef)
· $label (string)
widget = Gtk2::RadioButton->new_with_mnemonic
($member_or_listref=undef, $label=undef)
· $member_or_listref (scalar) reference to radiobutton group or a
Gtk2::RadioButton belonging to that group.
· $label (string)
Create a radio button with a mnemonic; this is an alias for "new".
widget = Gtk2::RadioButton->new_with_mnemonic_from_widget ($group,
$label=undef)
· $group (Gtk2::RadioButton or undef)
· $label (string)
$group = $radio_button->get_group
Return a reference to the radio group to which $radio_button
belongs. The group is a reference to an array of widget
references; the array is not magical, that is, it will not be
updated automatically if the group changes; call "get_group" each
time you want to use the group.
$radio_button->set_group ($member_or_listref)
· $member_or_listref (scalar) reference to the group or a
Gtk2::RadioButton belonging to that group.
Assign $radio_button to a new group.
PROPERTIES
'group' (Gtk2::RadioButton : writable / private)
The radio button to whose group this widget belongs.
