Hello, while discussing a question on StackOverflow, I learned that a ToggleGroup actually does not manage its toggles, but the toggles are responsible to ensure that only one of them is selected at a time.
This topic came up because I want to apply exactly the same behavior of RadioMenuItems in a ToggleGroup to a group of TitledPanes, which cannot be placed in the same parent and therefore cannot reside in an Accordion (as far as I understand it.) To solve my problem I implemented an Adapter that basically maps the corresponding properties of the TitledPane to the one required by the Toggle interface - and this did not work as expected. Now, being a curious person, I would like to understand, why it is that the ToggleGroup actually does not handle manage the selected state of its toggles. Does anyone know the background story behind this or is it something very obvious I just don't see yet?
