我正在查看 3 个传感器。传感器 1-3 都需要为 !=0，直到启用生成按钮才能将代码（由用户在传感器中选择）放入层次结构视图中。
我确实有这个工作，但只有当你选择一个又一个的顶部太底部时。
（例如：如果您选择中间传感器 (2)，然后选择顶部 (1)，然后选择底部 (3) - 生成按钮保持灰色且无法生成。）
是否有技巧可以让用户可以以无序方式选择这个？
我立即想到了 and/or 运算符，但 Java 没有。

I have 3 sensors I am looking at. Sensors 1-3, all need to be !=0 until the generate button is enabled to throw the code (that was selected in the sensors by the user) into a hierarchy view.
I do have this working, but only when you select one after another top too bottom.
(example: If you select the middle sensor (2), then the top (1), and then the bottom (3) - generate button stays greyed out and unable to generate.)
Is there a trick to make it so the user can select this in an unordered fashion?
I immediately thought of and/or operators, but Java does not have that.

从需求的描述来看，听起来好像是 3 x JRadioButton rel="nofollow">
ButtonGroup就可以了。From the description of the requirement, it sounds as though 3 x
JRadioButtonin aButtonGroupwould do the trick.
