NAME

       Gtk2::RadioButton

SYNOPSIS

	 # first group
	 $foo1 = Gtk2::RadioButton->new (undef, 'Foo One');
	 $foo2 = Gtk2::RadioButton->new ($foo1, 'Foo Two');
	 $foo3 = Gtk2::RadioButton->new ($foo2, 'Foo Three');

	 # second group, using the group reference
	 $bar1 = Gtk2::RadioButton->new (undef, 'Bar One');
	 $group = $bar1->get_group;
	 $bar2 = Gtk2::RadioButton->new ($group, 'Bar Two');
	 $bar3 = Gtk2::RadioButton->new ($group, 'Bar Three');

	 # move bar3 from the bar group to the foo group.
	 $bar->set_group ($foo->get_group);

	 # iterate over the widgets in the group
	 $group = $foo1->get_group;
	 foreach my $r (@$group) {
	     $r->set_sensitive ($whatever);
	 }

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)
       o   $member_or_listref (scalar) reference to radiobutton group or a Gtk2::RadioButton belonging to that group.

       o   $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)
       o   $group (Gtk2::RadioButton or undef)

       o   $label (string)

   widget = Gtk2::RadioButton->new_with_label ($member_or_listref=undef, $label=undef)
       o   $member_or_listref (scalar) reference to radiobutton group or a Gtk2::RadioButton belonging to that group.

       o   $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)
       o   $group (Gtk2::RadioButton or undef)

       o   $label (string)

   widget = Gtk2::RadioButton->new_with_mnemonic ($member_or_listref=undef, $label=undef)
       o   $member_or_listref (scalar) reference to radiobutton group or a Gtk2::RadioButton belonging to that group.

       o   $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)
       o   $group (Gtk2::RadioButton or undef)

       o   $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)
       o   $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 whose group this widget belongs to.

SIGNALS

       group-changed (Gtk2::RadioButton)
