IMPLEMENT_DYNAMIC_CLASS(wxRadioBox, wxControl)

// there are two possible ways to create the radio buttons: either as children
// of the radiobox or as siblings of it - allow playing with both variants for
// now, eventually we will choose the best one for our purposes
//
// two main problems are the keyboard navigation inside the radiobox (arrows
// should switch between buttons, not pass focus to the next control) and the
// tooltips - a tooltip is associated with the radiobox itself, not the
// children...
//
// the problems with setting this to 1:
// a) Alt-<mnemonic of radiobox> isn't handled properly by IsDialogMessage()
//    because it sets focus to the next control accepting it which is not a
//    radio button but a radiobox sibling in this case - the only solution to
//    this would be to handle Alt-<mnemonic> ourselves
// b) the problems with setting radiobox colours under Win98/2K were reported
//    but I couldn't reproduce it so I have no idea about what causes it
//
// the problems with setting this to 0:
// a) the tooltips are not shown for the radiobox - possible solution: make
//    TTM_WINDOWFROMPOS handling code in msw/tooltip.cpp work (easier said than
//    done because I don't know why it doesn't work)
