31.     --  A Gtk_Radio_Button is a simple button that has two states, like a

32.     --  Gtk_Toggle_Button. However, Gtk_Radio_Buttons can be grouped together to

33.     --  get a special behavior: only one button in the group can be active at any

34.     --  given time. Thus, when the user selects one of the buttons from the group,

35.     --  the button that was previously selected is disabled.

36.     --

37.     --  The radio buttons always belongs to a group, even if there is only one in

38.     --  this group.
