performs the same basic function as a
as it's 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
is used to give the user a choice of one of many options.
Radio button widgets are created with gtk.RadioButton() passing
None as the
group (first) argument
if this is the first radio button in a group. In subsequent calls, pass a
reference to a
as the first argument to specify the group. The second (optional) argument
to gtk.RadioButton() is a
label that is used to specify the text of the button. The label text is
parsed for mnemonic characters (preceded by an underscore) to specify an
accelerator for the radiobutton. See
for more information on mnemonic accelerators.
