RadioButtons activity

["Arthur Maciel" <arthurmaciel gmail com>]

Hi there.

I´m building a  RadioButton::Group and creating RadioButtons with that
group. I really want to set all radiobuttons DEactivated, but one of
them (the first) is always active.
I´ve already tried radio_button->set_active(false); to all of them,
but it did not worked. Could anyone help me, please?

Thanks.
Arthur
