ComboRadioSelector
This is compound widget for selecting categorized choices. The
categories are presented in a combo box, and the choices are shown below
as a set of radio buttons that is dynamically generated every time the
category is changed.
When a category is selected, the previous choice for that category is
remembered and re-selected.
The choiceChanged signal is emitted any time the current choice is
changed. This includes when the category combo is changed by the user and
when the current choice is changed programmatically via the
setCurrentChoice() method.
