public class ButtonGroupTag
extends ComponentTag

Implements a ButtonGroup. This tag acts like a Swing component except that adding a component other than an AbstractButton, will be passed through to the parent tag. This is meant to make the buttonGroup easier to use like this:

 <panel>
  <buttonGroup>
      <panel>
          <radioButton/>
      </panel>
      <panel>
          <radioButton/>
      </panel>
  </buttonGroup>
 </panel>
 

Note that the following construct will silently fail, and shame on s/he who even tried it:

 <panel>
  <buttonGroup>
      <font .../>
      <panel>
          <radioButton/>
      </panel>
      <panel>
          <radioButton/>
      </panel>
  </buttonGroup>
 </panel>
