Gtk2::RadioButton # 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); } 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.

widget = Gtk2::RadioButton->new ($member_or_listref=undef, $label=undef)
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)

widget = Gtk2::RadioButton->new_with_label ($member_or_listref=undef, $label=undef)
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)

widget = Gtk2::RadioButton->new_with_mnemonic ($member_or_listref=undef, $label=undef)
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 = $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)
Assign $radio_button to a new group. The radio button whose group this widget belongs to.
