I don't think the existing documentation stresses the point enough that if you use individual TRadioButtons you won't be able to use ItemIndex to find out which one is checked. Creating a TRadioGroup as a container then adding TRadioButtons to it does nothing useful, ItemIndex is always -1. Change Parent doesn't seem to fix it. It seems like that worked in Delphi, I rarely used string lists.
To use ItemIndex you have to populate the TRadioGroup using strings. I haven't found out yet whether the strings can be changed under program control, but I was building a context-sensitive menu, planning on changing the captions on the buttons to suit the context New to the list, I've got a resume at http://devio.us/~ab1jx/files/resume.pdf I used mostly Delphi 3 from when it first fascinated me about 1998 through the end of my last job in 2009. Turbo Pascal before that, VAX and Apple II Pascal before that. Used to tinker with Oberon Native. I spend most of my time in OpenBSD lately so I've been writing C for the last 6-7 years. Delphi was the thing I missed most about Windows.
