I updated the example in git to show using a single handler and value
(On_Change for radios is only called when a radio is selected not
deselected, which makes checking for Radio.Checked unnecessary):
procedure Radio_Select (Element : in out Gnoga.Gui.Base.Base_Type'Class)
is
Radio : Form.Radio_Button_Type renames Form.Radio_Button_Type
(Element);
begin
Gnoga.Log ("Radio Group #" & Radio.Value & " is now the checked
radio");
end Radio_Select;
for i in Radio_Group'Range loop
Radio_Group (i).Create (F, Name => "Group1", Value => i'Img);
Radio_Group (i).On_Change_Handler (Radio_Select'Unrestricted_Access);
F.Put ("Radio Group #" & i'Img);
F.New_Line;
end loop;
