ToggleGroup.getToggles()

一个人可以访问ToggleGroup的所有Toggles.但是，从切换到链接到的RadioButton是否有任何引用?

推荐答案

如果我正确理解了您要查找的问题:

If I understood the question correctly you're looking for:

RadioButton button = (RadioButton) toggleGroup.getSelectedToggle();

不幸的是，ToggleGroup尚未通用化"，因此您需要演员表.

Unfortunatly, the ToggleGroup isn't "generified" yet, so you need the cast.

但是从Toggle到RadioButton是否有任何引用， 链接到?

But is there any reference from a Toggle to the RadioButton that is linked to?

或者换句话说:RadioButton是一个(实现)切换，没有任何引用.

Or in other words: RadioButton is a (implements) Toggle, there isn't any reference.
