NAME

SYNOPSIS

9         # first group
10         $foo1 = Gtk2::RadioButton->new (undef, 'Foo One');
11         $foo2 = Gtk2::RadioButton->new ($foo1, 'Foo Two');
12         $foo3 = Gtk2::RadioButton->new ($foo2, 'Foo Three');
13
14         # second group, using the group reference
15         $bar1 = Gtk2::RadioButton->new (undef, 'Bar One');
16         $group = $bar1->get_group;
17         $bar2 = Gtk2::RadioButton->new ($group, 'Bar Two');
18         $bar3 = Gtk2::RadioButton->new ($group, 'Bar Three');
19
20         # move bar3 from the bar group to the foo group.
21         $bar->set_group ($foo->get_group);
22
23         # iterate over the widgets in the group
24         $group = $foo1->get_group;
25         foreach my $r (@$group) {
26             $r->set_sensitive ($whatever);
27         }

DESCRIPTION

30       A single radio button performs the same basic function as a
31       Gtk2::CheckButton, as its position in the object hierarchy reflects.
32       It is only when multiple radio buttons are grouped together that they
33       become a different user interface component in their own right.
34
35       Every radio button is a member of some group of radio buttons.  When
36       one is selected, all other radio buttons in the same group are dese‐
37       lected.  A Gtk2::RadioButton is one way of giving the user a choice
38       from many options; Gtk2::OptionMenu and Gtk2::ComboBox (added in gtk+
39       2.4) are alternatives.
40
41       Each constructor can take either a group or widget from that group
42       where the group is wanted; this is an enhancement over the C API.  Nev‐
43       ertheless, the _from_widget forms are provided for completeness.

METHODS

61       widget = Gtk2::RadioButton->new ($member_or_listref=undef,
62       $label=undef)
63
64           * $member_or_listref (scalar) reference to radiobutton group or a
65           Gtk2::RadioButton belonging to that group.
66           * $label (string)
67
68           Create a radio button.  If $label is provided, it will be inter‐
69           preted as a mnemonic.  If $member_or_listref is undef, the radio
70           button will be created in a new group.
71
72       widget = Gtk2::RadioButton->new_from_widget ($group, $label=undef)
73
74           * $group (Gtk2::RadioButton or undef)
75           * $label (string)
76
77       widget = Gtk2::RadioButton->new_with_label ($member_or_listref=undef,
78       $label=undef)
79
80           * $member_or_listref (scalar) reference to radiobutton group or a
81           Gtk2::RadioButton belonging to that group.
82           * $label (string)
83
84           Create a radio button with a plain text label, which will not be
85           interpreted as a mnemonic.
86
87       widget = Gtk2::RadioButton->new_with_label_from_widget ($group,
88       $label=undef)
89
90           * $group (Gtk2::RadioButton or undef)
91           * $label (string)
92
93       widget = Gtk2::RadioButton->new_with_mnemonic ($mem‐
94       ber_or_listref=undef, $label=undef)
95
96           * $member_or_listref (scalar) reference to radiobutton group or a
97           Gtk2::RadioButton belonging to that group.
98           * $label (string)
99
100           Create a radio button with a mnemonic; this is an alias for "new".
101
102       widget = Gtk2::RadioButton->new_with_mnemonic_from_widget ($group,
103       $label=undef)
104
105           * $group (Gtk2::RadioButton or undef)
106           * $label (string)
107
108       $group = $radio_button->get_group
109
110           Return a reference to the radio group to which $radio_button
111           belongs.  The group is a reference to an array of widget refer‐
112           ences; the array is not magical, that is, it will not be updated
113           automatically if the group changes; call "get_group" each time you
114           want to use the group.
115
116       $radio_button->set_group ($member_or_listref)
117
118           * $member_or_listref (scalar) reference to the group or a
119           Gtk2::RadioButton belonging to that group.
120
121           Assign $radio_button to a new group.
